Agent Vetting Bureau — Static security dossier of an MCP server / agent endpoint: endpoints, data flows, network calls, exfil signals, permissions requested, deterministic reputation score. Params: url (http/https).

Provably-fair draw from the drand beacon with the full verifiable receipt + nonce-binding (the free draw is at GET /random).

Curated reading list on American wit and humor for tutoring agents, quiz generators, and reading apps — 133 public-domain books (e.g. Comic History of the United States, Jokes For All Occasions Selected and Edited by One of America's Foremost Public Speakers, Fables in Slang). Full-text retrieval with drill-down routes for chapters, quotes, and citations. No license, no API key required.

Balances for up to 500 Animica accounts in ONE batched call, head-pinned, amounts in nANM as exact decimal strings. Single-address balance lookups stay free on the public API — this sells the batch.

Exact structured diff. mode=text -> unified diff + line counts; mode=json -> an RFC 6902 JSON Patch (RFC 6901 pointers) that round-trips a->b; mode=words -> inline word-level opcodes. For large inputs use POST. Every answer signed. Free sample, no payment required: GET /play/diff

Validate payment card numbers: Luhn checksum plus network detection (Visa, Mastercard, Amex, Discover, Diners, JCB, UnionPay, Maestro) with per-network length rules. Returns the network, Luhn result, and last four digits. Structure only — never that the card exists or has funds. No card data is stored or logged. POST a JSON body like: {"card":"4111 1111 1111 1111"}

Parse any CSS color (hex, rgb(), hsl()) and emit all three formats plus relative luminance. Compute WCAG contrast ratios against a background with AA/AAA pass-fail for normal and large text, and lighten, darken, or mix colors. Built for agents generating accessible UI themes. POST a JSON body like: {"color":"#3498db","background":"#ffffff"}

Validate and parse phone numbers in international E.164 form: extract the country calling code and region, the national number, and the canonical +E.164 string. Single number or a batch of up to 50. Format validation, not a line-in-service check. POST a JSON body like: {"phone":"+14155552671"}

Validate a JSON value against a JSON Schema and coerce common LLM-output mistakes (numbers as strings, stringified booleans, scalars where arrays are expected, missing defaults, extra properties). Returns the coerced value plus a structured error report. Built for cleaning up LLM tool-call arguments and structured outputs. POST a JSON body like: {"schema":{"type":"object","required":["name","age"],"properties":{"name":{"type":"string"},"age":{"type":"integer"}}},"data":{"name":"Ada","age":"36"}}

IPv4 and IPv6 address inspection and subnet math. Inspect an address (version, normalized form, classification: private/loopback/link-local/multicast/global, integer), compute a CIDR block (network, netmask, broadcast, host range, counts), or test whether an address falls inside a range. Deterministic, no lookups. POST a JSON body like: {"cidr":"192.168.1.0/24"}

Generate cryptographic secrets with CSPRNG randomness and honest entropy accounting: random bytes (hex/base64/base64url), passwords with character-class guarantees, pronounceable strings, UUIDs, prefixed API keys, TOTP seeds (base32), and asymmetric keypairs (Ed25519, ECDSA P-256, RSA-2048) as PEM + JWK. Unbiased rejection sampling. Secrets are never stored or logged. POST a JSON body like: {"type":"password","length":24,"symbols":true,"count":2}

Exact computation LLMs cannot do reliably: evaluate arithmetic expressions (trig, logs, powers, factorials, constants), convert between 80+ units across 11 dimensions (length, mass, temperature, data, speed, energy, pressure...), and compute descriptive statistics (mean, median, stdev, percentiles) over up to 100k numbers. Deterministic, no hallucinated arithmetic.
