| Endpoint | What it does | Price | Health |
|---|---|---|---|
| datemath add /datemath_add | Adds years/months/days to date. years/months are applied together with end-of-month clamping — e.g. 2026-01-31 + 1 month = 2026-02-28, not an overflowed 2026-03 | $0.0020 per call | unknown |
| datemath age /datemath_age | Age in whole years as of asOf (optional, defaults to the current UTC date). A Feb-29 birthDate is treated as falling on March 1 in a non-leap asOf year. | $0.0020 per call | unknown |

| datemath diff /datemath_diff | Day difference between two YYYY-MM-DD dates: to minus from, in whole days. Negative if to is before from. | $0.0020 per call | unknown |

| email validate /email_validate | Checks value is a single, bare RFC 5322 email address — syntax only, not a deliverability check. user@localhost is valid (no TLD required). "Name <email>" displ | $0.0020 per call | unknown |
| hash digest /hash_digest | Computes a hash digest of input (decoded per encoding: "text" default, "base64", or "hex") using algo: md5, sha1, sha256, sha512, or crc32. Returns the digest a | $0.0020 per call | unknown |

| pesel validate /pesel_validate | Validates the checksum of an 11-digit Polish national identification number (PESEL). Checksum uses weights 1 3 7 9 1 3 7 9 1 3 over the first 10 digits; control | $0.0020 per call | unknown |
| regex match /regex_match | Tests input against pattern (Go's regexp package: RE2 syntax, not PCRE — no backreferences or lookaround; use inline flags like (?i) for case-insensitive matchi | $0.0020 per call | unknown |
| regon validate /regon_validate | Validates the checksum of a 9- or 14-digit Polish business registry number (REGON). 9-digit: weights 8 9 2 3 4 5 6 7 over the first 8 digits, sum mod 11 (10 map | $0.0020 per call | unknown |
