235 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Breached password check: is this password in known data breaches, and how often? Send only the SHA-1 hash (never the password); just the first 5 characters reach Have I Been Pwned (k-anonymity). Up to 50 hashes per call.
DNS check for a domain: does it resolve, plus A, MX and NS records. Input: d.
Conservatively repair common JSON syntax errors (unquoted keys, single-quoted strings, trailing commas) and parse the result; input is never evaluated as code.
Compare two texts line by line: unified diff, list of added, removed and changed lines, line and character similarity, optionally ignoring whitespace and case. Use to compare documents, configs or model outputs.
Convert a value between units of length, area, volume, mass, energy (kWh, MWh, BTU, GJ), power, pressure, temperature, speed, data size, time and compound units like kg/m^3 or mpg. Exact, no lookup tables to maintain.
The smallest paid call: returns the server's UTC time and echoes your message. Use to test an x402 client, wallet and payment flow end to end before calling bigger tools.
IANA timezone lookup for agents: offset, abbreviation, DST and local time for $0.002 USDC—stdlib zoneinfo, no API key. Call when you need this bounded result without an API key or subscription. Returns machine-readable J...
List observed US federal holidays for a year for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover...
Business-day counter for agents: weekdays or US federal holidays for $0.002 USDC—first-party calendar, no third-party API. Call when you need this bounded result without an API key or subscription. Returns machine-readab...
Unit conversion API for agents: length, mass, volume, time, data and temperature (up to 100 conversions per call) for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machin...
Detect a file's real format from its first bytes (magic numbers), given as base64 or hex: MIME type, extension and a warning when it does not match the file name. Use to validate uploads.
MD5, SHA-1, SHA-256, SHA-512, SHA3-256, Keccak-256, BLAKE2b and CRC32 of a text or hex/base64 bytes, plus base64 and hex encodings, in one call. Use for integrity checks, IDs, signatures and Ethereum selectors.
Validate JSON (with line and column of errors), pretty-print, minify, sort keys, list all paths, show its shape, or extract a value by path like $.items[0].name or $.items[*].
Cryptographically secure random values: UUID v4 or v7, strong passwords, hex or URL-safe tokens, integers in a range, dice rolls or coin flips, up to 100 at once.
