AI vision: describe any public image, including visible text (OCR-lite).

Is a date a public holiday in a country (2-letter ISO code)? Returns the holiday name, its types, and the next upcoming holiday that year.

Pick one or several options at random from a caller-supplied list (CSPRNG), optionally without replacement — a decision-maker for agents.

Word, sentence, and paragraph counts, reading time, and readability score for text.

Skip the maze — clean, honest, trap-free access.

Deep horse-form analysis with ratings and trainer stats. For horse-racing handicapping agents.

Cryptographically secure random picker for 2-100 JSON choices. Use for low-stakes one-off random or weighted selection, unbiased tie-breaking, and sampling. Returns the selected value and index, request ID, and weight totals for audit logs. $0.001 USDC per paid request. Not for stable assignments, gambling, security tokens, or consequential decisions; outcomes are not provably fair.

Returns a single random fact as JSON in exchange for a micropayment.

Get a random interesting joke. Secured with x402 payment protocol on Base mainnet.

Use when an agent needs numbers in a range that will stand up to inspection: uniform random integers between your own bounds, with or without repeats, drawn with rejection sampling so the ends of the range are not slightly less likely, which is what modulo does. Do not use to choose among items (/v1/random/pick) or for a secret (/v1/random/password).

Randomness for agents: flip coins, roll dice, draw numbers in a range, pick from a list or shuffle it. Cryptographically secure by default; with verifiable=true it is derived from the latest public NIST Randomness Beacon pulse and your seed, so anyone can verify the result.

Use when an agent has several options and no reason to prefer any, and the choice has to be defensible: picks one or more items from the list you send, with or without repeats, and tells you how many it had to choose from. Do not use to order the whole list (/v1/random/shuffle) or to draw a number in a range (/v1/random/number). No API key, no account.

Generate one or more uniformly-distributed random integers in an inclusive [min, max] range.

Draw a random sample from a provided array — without replacement by default (a fair shuffle), or with replacement when unique is false. count defaults to 1.

Generate a random string of a given length from a named charset (alphanumeric, alpha, lower, upper, numeric, hex, base58) or a custom alphabet. Unbiased character selection.
