• age_calculator≈ 252 tokens

  An age calculator: your exact age in years, months and days, from a date of birth. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (2)

  Paramètres

  • asOf · string · optionnel
    The date to measure the age at, YYYY-MM-DD. Omitted, the server's own UTC date is used, which can be a day out for the caller near midnight, so pass it when the exact day matters. Must not be before the birth date. The response echoes the date it used.
  • birth · string · requis
    Date of birth as YYYY-MM-DD. Read as a calendar date with no time zone, so the answer is the same wherever it is asked from.

• app_background_preview≈ 752 tokens

  Find the app background image size that survives on every phone and tablet. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (7)

  Paramètres

  • mode · string · optionnel · fill | fit | stretch | center
    How the platform scales the image onto the screen. fill scales until both axes are covered and crops the overflow, centred; fit shows the whole image with empty bars (letterboxed); stretch shows the whole image distorted to the screen's shape; center shows a screen-sized window at native scale from the middle of the image.
  • kinds · array · optionnel
    Narrow the check to phones, tablets or foldables. Omitted or empty, all three are included. Applied on top of devices, so the two filters compose. Leaving foldables in when you do not ship to one shrinks the safe area, because a foldable opened out is nearly square.
  • width · integer · requis
    Width of the artwork in pixels. Only the width-to-height ratio affects the crop, so any resolution with the same shape gives the same answer; the rectangles in the response are in these pixels.
  • height · integer · requis
    Height of the artwork in pixels, paired with width.
  • devices · array · optionnel
    Which device shapes to check. Omitted or empty, every device is checked. Each id is one aspect ratio standing for all the models that share it; the response names those models. The safe area is the intersection across everything checked, so fewer devices means a larger safe area.
  • orientations · array · optionnel
    Which orientations to check each device in. Omitted or empty, both portrait and landscape are checked, and both feed the safe-area intersection.
  • respectInsets · boolean · optionnel
    When true, the safe area is taken over the part of each screen not covered by the status bar, notch or home indicator, so it is safe from being covered as well as from being cropped. False (the default) considers cropping only.

• ascii_table≈ 282 tokens

  The full ASCII table, with the control codes explained rather than left blank. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (2)

  Paramètres

  • search · string · optionnel
    What to look up: a single character ("A"), a decimal code ("65"), hex ("0x41", "U+0041", "\x41"), binary ("0b01000001"), octal ("0o101"), an HTML entity ("&"), an abbreviation ("LF") or part of a name ("line feed", "sep"). Numbers return one entry; names return every match, best first. Plain digits are always decimal. Empty (the default) returns the whole table.
  • includeExtended · boolean · optionnel
    Also include codes 128 to 255, read as ISO-8859-1 (Latin-1). ASCII proper stops at 127, so a search for a higher code finds nothing unless this is true.

  Paramètres, retour & exemple (2)

  Paramètres

  • text · string · requis
    The document's plain text, as extracted from the PDF, not the file itself. It is sent to a language model, which returns the personal names and postal addresses found in it, each exactly as written; the caller maps them back to positions. Emails, phone and card numbers are not returned, since patterns catch those locally. At least 40 characters and at most 120000.
  • language · string · optionnel
    The language the document is most likely in, such as "Danish", passed to the model as a hint because it changes what a name looks like. A hint only: a wrong guess does not stop the text being read, and omitting it is fine.

• average_calculator≈ 224 tokens

  A mean median mode calculator, with standard deviation and the spread. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (1)

  Paramètres

  • numbers · string · requis
    The list of numbers as one string, separated by commas, spaces, line breaks or anything else that is not a digit, sign or decimal point. Use a decimal point, never a decimal comma: "1,5" is read as two numbers. Anything unparseable is skipped, and at least one number must remain. Returns mean, median, mode, range and both standard deviations.

• avif_converter≈ 516 tokens

  AVIF to JPG, and JPG to AVIF — the format that halves a photograph. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (6)

  Paramètres

  • data · string · requis
    The image file's bytes, base64-encoded: JPEG, PNG, WebP, GIF or AVIF. At most 30 MB decoded. An animated GIF is converted to a still of its first frame, and the response says so with note: "animation-dropped".
  • name · string · optionnel
    The original filename. Only used to name the result: its extension is swapped for the output format's, so photo.jpg comes back as photo.avif.
  • type · string · optionnel · image/jpeg | image/png | image/webp | image/gif | image/avif
    The MIME type of the bytes in data. The image pipeline reads all of these; the actual format is taken from the bytes, so a wrong value here is not fatal.
  • format · string · optionnel · image/avif | image/webp | image/jpeg | image/png
    The format to produce. AVIF is what the tool is for; WebP, JPEG and PNG exist so an AVIF can be converted back to something older software opens.
  • quality · integer · optionnel
    Encoder quality, 1 (smallest, roughest) to 100 (largest). Ignored for PNG, which is lossless. The default of 60 is deliberate: AVIF at 100 is often larger than the JPEG it replaces.
  • maxWidth · integer · optionnel
    Scale the image down so its width is at most this many pixels, keeping the aspect ratio. Never enlarges. Omit to keep the original dimensions.

• background_remover≈ 566 tokens

  Remove the background from an image — solid backgrounds go transparent, in your browser. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (7)

  Paramètres

  • data · string · requis
    The image file's bytes, base64-encoded. This removes a flat, single-colour background such as a white product shot or a scan; it is not a subject cutout for photos with busy backgrounds.
  • name · string · optionnel
    The original filename. Used only to name the result, whose extension becomes .png because the output is always a PNG with transparency.
  • type · string · requis · image/jpeg | image/png | image/webp
    The MIME type of the bytes in data: JPEG, PNG or WebP.
  • reach · string · optionnel · edges | everywhere
    edges (the default) removes only background connected to the image border, so enclosed areas like the hole in a letter or a window behind someone stay. everywhere removes every pixel within tolerance wherever it is.
  • colour · string · optionnel
    The background colour to remove, as #rrggbb hex. Omit to sample it from the four corners of the image; the response reports the colour used and whether the corners agreed on it.
  • feather · number · optionnel
    How soft the edge is, 0 to 100. It widens the band of partly transparent pixels around the tolerance threshold, as a percentage of tolerance; 0 gives a hard jagged cut.
  • tolerance · number · optionnel
    How far a pixel's colour may be from the background colour and still be removed, 0 to 100 as a share of the largest possible RGB distance. Raise it for uneven lighting or JPEG noise; too high eats into the subject.

• barcode_generator≈ 447 tokens

  A barcode generator for EAN-13, UPC-A, EAN-8 and Code 128 — check digit included. A HelpySelf tool (helpyself.com).

  Paramètres, retour & exemple (5)

  Paramètres

  • text · string · requis
    What to encode. For ean13, upca and ean8 this is digits only: 12, 11 or 7 of them and the check digit is worked out, or one more and it is verified (a wrong one is refused rather than drawn). For code128 it is any printable ASCII up to 80 characters.
  • scale · integer · optionnel
    Width of the narrowest bar in pixels; every other width and the quiet zones are multiples of it, so this sets the overall size. 3 is about right for a screen.
  • height · integer · optionnel
    Height of the bars in pixels. The printed number and the longer guard bars add to the total height of the SVG when showText is true.
  • showText · boolean · optionnel
    Print the encoded value underneath the bars, as a retail barcode always does. False gives bars only.
  • symbology · string · optionnel · ean13 | upca | ean8 | code128
    Which barcode standard to draw. ean13 (13 digits, the retail default worldwide), upca (12 digits, North American retail), ean8 (8 digits, small packaging), code128 (letters, digits and punctuation, for labels and logistics).

  Paramètres, retour & exemple (3)

  Paramètres

  • text · string · requis
    The text to encode, or the Base64 to decode, depending on action. Encoding goes through UTF-8 first, so accents, emoji and CJK survive. Decoding accepts standard or URL-safe Base64, with or without padding, and ignores whitespace.
  • action · string · optionnel · encode | decode
    encode turns text into Base64; decode turns Base64 back into UTF-8 text. Defaults to encode.
  • urlSafe · boolean · optionnel
    When encoding, use the URL-safe alphabet (RFC 4648 section 5): + and / become - and _, and the = padding is dropped, as in JWTs. Ignored when decoding, which detects either alphabet.

  Paramètres, retour & exemple (2)

  Paramètres

  • input · string · requis
    Plain text, or bytes written as binary, hex, decimal or octal. Groups may be separated by spaces or commas; hex also accepts 0x prefixes and unspaced pairs. Every other representation of the same bytes comes back at once, so there is no direction to choose. Text is treated as UTF-8, so "é" is two bytes.
  • readAs · string · optionnel · auto | text | binary | hex | decimal | octal
    How to read input. auto (the default) works it out: only 0s and 1s in whole bytes is binary, hex digits with a letter or 0x is hex, several zero-padded pairs is hex, several numbers up to 255 is decimal, anything else is text. Octal is never guessed, since "17" is valid octal and decimal, so name it explicitly. Byte values over 255 are refused.

  • draw · string · optionnel · seeded | shuffled
    `seeded` treats the order given as the rankings: the first two can only meet in the final and byes go to the top. `shuffled` draws at random, which is what an office sweepstake wants. Either way the order is fixed once the bracket exists.
  • title · string · requis
    The tournament's name, shown as the page heading. Up to 80 characters.
  • players · array · requis
    Everybody in the draw, 4 to 64. Any number works — one that is not a power of two gets byes in the first round, placed against the top seeds so no bye faces another and both halves play the same number of rounds.

  Paramètres

  • data · string · requis
    The image file as base64, in the format given by type.

    How the new size is given: 'dimensions' uses width and height in pixels, 'percentage' scales both sides by percentage and ignores width and height.
  • name · string · optionnel
    The source filename. The result is named after its stem with the new size appended, e.g. 'photo-800x600.jpg'.

    The MIME type of the source image: image/jpeg, image/png or image/webp.
  • width · integer · optionnel
    The target width in pixels, for the 'dimensions' mode. With keepAspect on, giving a width sets the height from it and any height given is ignored. Omitted with keepAspect off, the source width is kept.
  • format · string · optionnel · image/jpeg | image/png | image/webp
    The output format: image/jpeg, image/png or image/webp. Omit it to keep the source format.
  • height · integer · optionnel
    The target height in pixels, for the 'dimensions' mode. With keepAspect on it only applies when width is omitted, and then sets the width from it.
  • quality · number · optionnel
    Encoder quality from 0.1 to 1 for JPEG and WebP output; lower is smaller and softer. PNG is lossless and ignores it.
  • keepAspect · boolean · optionnel
    Keep the source proportions in 'dimensions' mode, so one of width or height drives the other. Set false to stretch to an exact width and height.
  • percentage · number · optionnel
    The scale for the 'percentage' mode, as a percentage of the source size per side: 50 halves both edges, 100 leaves it as is. Over 100 needs allowUpscale.
  • allowUpscale · boolean · optionnel
    Allow a result larger than the source on either side, up to 10000 pixels. Off by default, so enlarging is refused with an explanation rather than adding blur.

  Paramètres, retour & exemple (4)

  Paramètres

  • data · string · requis
    The PDF to read, base64-encoded (a data: URL prefix is accepted). It needs a text layer: a scan with no text is refused with `no_text` rather than returning an empty workbook. Refused above 25 MB decoded.
  • joinPages · boolean · optionnel
    Treat a table that carries on over a page break as one table, dropping the repeated heading row. On by default, because a statement split across twelve pages is one table; turn it off to get one sheet per page.
  • sheetName · string · optionnel
    What to call a tab the document did not name — `Table` gives Table 1, Table 2. A table the document headed keeps its own heading instead, trimmed to what Excel allows and made unique if it has to be.
  • includeText · boolean · optionnel
    Also keep everything that was not in a table — headings and paragraphs, in reading order, with the page each came from — as a sheet of its own. On by default: on an invoice the total being charged is a line of prose above the tables rather than a row inside one, so a workbook of only the grids has lost the number the document is about.

  • errorCorrection · string · optionnel · L | M | Q | H
    How much of the code may be damaged or covered and still scan: L about 7%, M 15%, Q 25%, H 30%. Higher levels make a denser code for the same text.

  • smooth · boolean · optionnel
    Draw quadratic curves through the points instead of straight segments between them, which stops a signature looking ruler-drawn.

    Space left around the ink when trimming, measured in stroke widths rather than points units, so 2 at a strokeWidth of 3 is 6 units on every side.
  • strokes · array · requis
    The drawing as a list of strokes, each a list of points in the order the pen visited them, in any consistent unit. At most 20000 points in total. The result is an SVG path, so the units only matter relative to strokeWidth.

  • method · string · optionnel · area | income | equal
    How to divide it. `area` charges each person for their own room and splits `sharedArea` equally between everybody, which is the fair-rent answer. `income` is straight proportion to each person's income. `equal` ignores both.
  • people · array · requis
    Everybody splitting it, 1 to 20.
  • currency · string · optionnel
    ISO 4217 code, which decides how the rent is rounded: most currencies to two decimal places, the Gulf dinars to three, JPY and KRW to none. It does not convert anything — the shares come back in the currency the rent was given in.
  • sharedArea · number · optionnel
    Floor area nobody has to themselves — kitchen, hallway, sitting room — in the same unit as the rooms, split equally. Only used when method is `area`. Zero gives the simpler split where the whole rent follows bedroom size alone.

    A line shown under the title on the booking page: doors open, where to park, what not to bring.
  • price · integer · optionnel

  • stalls · integer · optionnel
    How many stalls to lay out in the rectangle. Required when no venueId is given. If fewer fit at the given stall size, fewer are made rather than the stalls being shrunk, and the response says how many. A free account is limited to a smaller market than Pro.

  • hallDepth · integer · optionnel
    Depth of the hall in centimetres. Required when no venueId is given.

  • holdHours · integer · optionnel
    How many hours a booked stall is held while the vendor pays, at most a week. If the organiser has not marked it paid by then, the stall is released for someone else to book.
  • backToBack · boolean · optionnel
    Lay rows out in pairs with their backs together and the aisle only between pairs, so the public cannot walk behind a seller. Fits more stalls in the same hall than a plain grid.
  • stallDepth · integer · optionnel
    Depth of one stall in centimetres, front to back.
  • stallWidth · integer · optionnel
    Width of one stall in centimetres, along the row. 180 is a standard trestle table.

  Paramètres

  • draws · integer · optionnel
    How many winners to draw. Without removeWinner each draw is from the full list, so the same name can win more than once. Defaults to 1.
  • names · string · requis
    The entries to draw from, one per line. Blank lines and surrounding spaces are ignored; a name listed twice has two chances.
  • removeWinner · boolean · optionnel
    Take each winner out of the list before the next draw, so no name wins twice. Drawing stops early if the list runs out; remaining in the response lists who is left.
