Agent skill
Tolca answers three questions in one call each:
Answers are deterministic JSON (no LLM in the loop): a verdict ok / review / blocking / not_found, reasons, sources with extraction dates, and a proof block (sha256 of the answer). Registry data is refreshed daily from Données Québec (CC-BY 4.0) and the federal and international sources listed below.

Pay per call (x402, for agents)
No signup. Your agent gets a 402 Payment Required, pays in USDC on Base, and gets the JSON back. Zero results = HTTP 404 = not charged.
Current prices and schemas: https://tolca.tonbot.ca/openapi.json and https://tolca.tonbot.ca/.well-known/x402
See examples/check.mjs:
Without a payment, the endpoint answers 402 Payment Required with the price in the PAYMENT-REQUIRED header:

Who it is for
- General contractors bidding on public contracts: a business listed in the RENA cannot obtain a public contract or a public subcontract. Check your whole subcontractor list before you bid.
- Property and condo managers, insurers, quote platforms: vet every supplier at signup and re-check them over time, keep a dated PDF in the file.
- AI agents and developers building procurement, compliance, home-renovation or research assistants: one call, cited answer, no account to manage.
Limits
Public data as of the extraction date shown in each answer. Name matching can return homonyms: confirm with the NEQ or licence number. Not a substitute for checking directly with the RBQ or the AMP. Insurance and CNESST status are not covered. Web search reads public pages only; pages that block robots are reported in pages_skipped.
