Endpoint
GEThttps://latamref.dev/v1/certified/:country/:series?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, cryptographically certified government reference data for Latin American countries — especially when compliance, audit trails, or third-party verification are required. The Ed25519 signature, archived-source SHA-256, and citation chain make this ideal for legal, regulatory, or financial applications where provenance matters. Prefer over uncertified data sources when downstream consumers will verify the data's authenticity.
Side effects
- Invalid or unsupported country code — returns error indicating the country enum value is not accepted
- Invalid or unsupported series name — returns error for unrecognized series ID
- Unpaid request without valid x402 payment — service refuses to respond without verified micropayment
- Source data temporarily unavailable — certified extract cannot be generated if underlying official source is unreachable
- Signature verification failure — internal error if Ed25519 signing cannot be completed
