How this service works
Ask about any company or Québec contractor and get a verdict grounded in official registries, not guesses. Plus web search that reads the pages for you. Pay per call, no account.
Output
A JSON object with a top-level verdict (ok, review, blocking, or not_found), a list of human-readable reasons, a sanctions block (status, matched list entries, data freshness timestamp), a legal_entity block (GLEIF LEI record with entity status, jurisdiction, and registration status), and a contractor_licences array if a region was provided. All checks are timestamped.
Example use cases
Pre-payment sanctions screening
“We're about to pay a vendor called Global Tech Supplies Ltd in the UK — can you screen them against US restricted-party lists and check their legal entity status before we send the wire?”
Onboarding a Québec subcontractor
“We're about to onboard a Québec-based contractor called Construction Moreau Inc. — can you verify they're not on any sanctions lists and that they hold an active RBQ contractor licence?”
Compliance check before signing a contract
“We're finalizing a contract with Pacific Northwest Builders based in Oregon — can you do a full KYB check to make sure they're not on any restricted-party lists and are properly licensed as a contractor in OR?”
Technical details
Endpoint
POSThttps://tolca.tonbot.ca/v1/verify-business?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single consolidated KYB verdict before paying, onboarding, or contracting a business — especially when you need to cross-check US sanctions (OFAC SDN, Entity List, Denied Persons), legal entity status via GLEIF, and regional contractor licences (WA, OR, QC) in one call without managing multiple API integrations. Prefer it over standalone OFAC screeners when you also need registry and licence verification, and over manual lookups when you need a machine-readable verdict with structured reasons for audit trails.
Side effects
- Business name not found in any checked registry — verdict returns not_found with reasons
- Ambiguous name matches multiple entities — may return review verdict requiring manual inspection
- Region code outside supported values (WA, OR, QC) causes contractor licence check to be skipped silently
- Invalid ISO-2 country code results in a validation error
- Payment not received (x402 protocol) — request rejected before processing
- External registry or sanctions list temporarily unavailable — partial results or error response
