Agent fortune API: a fortune cookie written specifically for AI agents ('A cached response is worth two upstream calls'), plus a lucky number and lucky HTTP status code. The cheapest, most delightful way to make your first x402 payment and verify your wallet stack works end to end. New fortune every call.

Computes a SHA-256 digest of any input text and returns it as a hex string, computed locally with no network round-trip to a third party. Also supports SHA-512, SHA-1, and MD5 on request. Useful for content fingerprints, cache keys, and deduplication logic where the same input must always produce the exact same output.

Produces an MD5 hash, or SHA-1, SHA-256, SHA-512 on request, of any text input as a hex digest, computed instantly with nothing stored. Useful for legacy checksum compatibility, quick fingerprinting, and integrity checks in pipelines that still expect an MD5 value alongside newer algorithms.

Temperature conversion API: any of Celsius, Fahrenheit, Kelvin, or Rankine to all four at once. Science-grade, exact.

Converts a given local time between IANA timezones with daylight-saving transitions applied correctly, so a meeting scheduled across the DST changeover lands on the right hour instead of one off. Returns local time, UTC ISO, and unix epoch for downstream calendar and reminder systems.

Timezone converter API: convert a wall-clock time from one IANA timezone to another with daylight-saving applied correctly — returns converted local time, UTC ISO, and unix epoch. 'What is 3pm Tokyo for Chicago?' deterministically. For scheduling and calendar agents.

Token and word counting API: characters, words, sentences, estimated LLM tokens, Flesch reading ease, and reading time for any text. Budgeting context windows and readability in one call.

Percentage API: X% of Y, X is what percent of Y, percent change, percent increase/decrease — all five, exact, one call.

Secure token generator API: cryptographically random UUIDs (batch up to 20), hex tokens, or unambiguous alphanumeric secrets (length 8-128) from OS-grade entropy. For request ids, nonces, temporary passwords, and API-key material. Generated locally, never logged.

Grant narrative writer for grant-writer and nonprofit agents. Returns professional narrative section drafts ready to customize, with data placeholders and strengthening tips.

Fortune cookie API for AI agents: a fortune written for language models, a lucky number, and a lucky HTTP status — the cheapest possible first x402 purchase. Come for the novelty, stay for the utility grid.
