Tolca: Québec contractor check (MCP + x402)

One call. Three official Québec public registries. A clear verdict.

Tolca checks a Québec construction contractor against:

The answer is deterministic JSON (no LLM in the loop): ok, review, blocking or not_found, with reasons, sources and extraction dates. Data is refreshed daily from Données Québec (CC-BY 4.0).

Pay per call from code (x402, for agents)

Separate from the free MCP server above. No signup. Your agent pays $0.50 USDC on Base per check and gets the JSON back.

See examples/check.mjs:

npm i @x402/fetch @x402/evm viem
PRIVATE_KEY=0x... node examples/check.mjs "Construction ABC inc."

Without a payment, the endpoint answers 402 Payment Required with the price in the PAYMENT-REQUIRED header:

curl -i -X POST https://tolca.tonbot.ca/v1/qc-contractor-check \
  -H "content-type: application/json" -d '{"name":"Neolect"}'

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: vet every supplier, keep a dated PDF in the file.

• Quote and renovation platforms: verify contractors at signup and re-check them over time.

• AI agents and developers building procurement, compliance or home-renovation assistants.

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.
