How this service works
Pay per call over x402. USDC on Base, no account, no API key. 28 government-sourced data products at $0.001–$0.05 per call, every response signed and provenance-chained.
Output
Returns a JSON object containing: one or more AQI data rows with field values and record IDs, the product name and version, a provenance chain with SHA-256 hash, authoritative agency name, source URL, and observation timestamp, a cryptographic attestation with signature, result digest, and signing key ID, and a payment receipt with USD amount and on-chain settlement reference.
Example use cases
Real-time air quality for site compliance
“Get me the latest AQI data for monitoring site '060371103' from Clink Forge — I need the signed provenance so I can confirm it came from an official government source before including it in our compliance report.”
Automated environmental health alert
“Look up the current air quality index for monitoring site '480290012' — if the AQI is above 100, flag it as unhealthy and include the cryptographic attestation in the alert so downstream systems can verify the data source.”
Verifiable AQI data for research pipeline
“Fetch the AQI readings for site '170310001' from Clink Forge and include the full provenance chain and hash — I'm building a dataset and need to be able to prove each record came from an official agency.”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/aqi-site-lookupWhen to prefer
Choose this endpoint when you need AQI data from a specific government monitoring station and require cryptographic provenance and attestation for trust, auditability, or compliance purposes. It is especially valuable for autonomous agents that must prove data authenticity without maintaining API accounts or keys, and when a per-call micropayment model in USDC is preferable to subscription billing. Prefer alternatives if you need broad geographic AQI search, real-time forecasting, or do not require provenance guarantees.
Side effects
- Missing or invalid 'id' query parameter returns a validation error
- Unknown or non-existent site ID returns empty data rows or a not-found error
- Insufficient USDC payment or failed x402 transaction results in a 402 Payment Required response
- Site ID exceeds 60-character maximum length causes a schema validation rejection
- Government data source temporarily unavailable may return stale or error response
- Network timeout during on-chain payment settlement
