Tolca: pay-per-call checks and tools, for people and AI agents

Tolca is an automated service that answers precise questions from official sources and public registries. Each call costs a few cents, paid automatically. A person can use it inside Claude or ChatGPT; software or an AI agent can call it directly.

Québec contractor check

Before signing with a construction or renovation contractor in Québec, one question: is everything in order?

In one call, Tolca cross-checks three official Québec registries and returns a clear verdict:

Verdict: OK, review or blocking, with reasons, sources and extraction date. Official open data (Données Québec, CC-BY), refreshed daily. 54,000 active licences covered.

For: quote comparison platforms, insurers, property managers, notaries, general contractors vetting subcontractors, careful homeowners.

$0.50 $0.50 per full check, or $0.02 for the RBQ licence only (qc-licence, built for bulk). 10 free checks per day through Claude or ChatGPT (see below). Monthly plans for platforms: get in touch.

Homeowners and managers: check here, pay by card

For developers and agents: pay per call (x402)

Each service is an HTTP address. Without payment you get a 402 with the price; an x402 client pays in USDC on Base and gets the answer. No account, no API key.
