Bazaar Metadata Check

Offline validator for a Mexican RFC (Registro Federal de Contribuyentes). Checks the format for persona física (4 letters + 6-digit date + 3-char homoclave) or persona moral (3 letters + 6-digit date + 3-char homoclave), verifies the embedded date is a real calendar date, and returns the parsed birth/incorporation date. Pure string/date logic, no network calls.

Offline validator for a Guatemalan CUI (Código Único de Identificación), the 13-digit national ID number. Parses the 13 digits into an 8-digit correlative, a 1-digit check digit, a 2-digit department code and a 2-digit municipality code, recomputes the check digit using the published weighted mod-11 formula (weights 2-9 over the 8 correlative digits, mod 11, 10→0) and compares it, returning validity plus the parsed components.

AI sound effect generation (ElevenLabs) — pay per call with USDC on Base

Pay-per-Attestation: an AI agent pays to seal its own decision (input hash, output, model, timestamp) in FractalAI's post-quantum L1 — Dilithium-3 (NIST FIPS 204) signed, Black-Box chained; on-chain anchoring (VAID-1) is attempted per call and reported in the response. Returns a re-verifiable receipt. Built for EU AI Act Art.12 record-keeping. x402-native.

Returns Markdown body, title, word count, and a quality grade. Web reader for article and main content. For JS-rendered or bot-walled pages a plain fetch can't read, use /exa/contents.

Pay-per-Training-Provenance: an agent pays to seal the provenance of a dataset or training run — a C2PA-compatible manifest binding the dataset/artifact hash to a declared origin, served with a post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over the same canonical claim (manifest anchor: Dilithium-3). Built for EU AI Act Art. 10/53 training-data provenance. Privacy-preserving (only the hash is bound). x402-native.

Pay-per-KYA: an agent pays to verify another agent's post-quantum identity + scope credential (Dilithium-2, NIST FIPS 204), with a live FRC-55 on-chain reputation read. ERC-8004-aligned Know Your Agent for autonomous agent-to-agent commerce. x402-native.
