How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns structured JSON with official Spanish company registration data (legal name, CIF/NIF, registered address, company type, status, and other firmographic fields) plus a Strale audit record with a cryptographic chain hash for provenance verification.
Example use cases
Supplier due diligence for procurement
“I need to verify our new Spanish supplier — their VAT number is ESB86502601. Can you pull their official company data so I can confirm they're legitimately registered?”
KYC check on Spanish counterparty
“We're onboarding a client who says they're a Spanish company called Inditex. Can you look them up by company name and get me their official CIF and registration details?”
Enrich CRM with Spanish company firmographics
“I have a lead with Spanish NIF A28015865 — can you fetch their official company information including legal name, address, and company type so I can update our CRM?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/spanish-company-dataWhen to prefer
Choose this endpoint when you need authoritative, auditable Spanish company data tied to official registry records, especially in compliance, KYC, or supplier verification workflows. Prefer it over generic web searches when you need structured firmographic output with a cryptographic audit trail. Best when you have a CIF/NIF or an unambiguous company name; avoid when only a vague or partial name is available since the endpoint refuses ambiguous matches.
Side effects
- Ambiguous company name rejected rather than guessed — endpoint refuses to return results if name match is not confident
- Invalid or malformed CIF/NIF format returns an error (must be letter + 7 digits + check character)
- Company not found in registry returns empty or 404-equivalent response
- Missing required query parameter (no nif/cif/name/query provided) returns a 400-level error
- Rate limiting or payment failure via x402 protocol returns 402 Payment Required
