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: an array of AQI category summary data rows sourced from government agencies, a provenance chain with SHA-256 hashes, authority name, source government URL, and observation timestamp, a cryptographic attestation with a base64 signature and result digest signed by a Clink Forge key, a payment receipt confirming the $0.02 USDC settlement, the product name and version, and a row count.
Example use cases
Air quality compliance dashboard
“Fetch the AQI category summary from Clink Forge so I can update our environmental compliance dashboard with the latest government-sourced air quality categories and their provenance signatures.”
Verifiable AQI data for research pipeline
“I need the AQI category summary data from Clink Forge for my research pipeline — make sure to include the provenance chain and attestation so I can prove the data came from an authoritative government source.”
Autonomous agent air quality monitoring
“Every hour, grab the AQI category summary from Clink Forge and flag any category changes — I want the cryptographic attestation included so the records are tamper-evident.”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/aqi-category-summaryWhen to prefer
Choose this endpoint when you need government-sourced AQI category summary data with verifiable, tamper-evident cryptographic provenance — ideal for autonomous agents, compliance workflows, or research pipelines where data authenticity must be proven. Prefer over generic weather/AQI APIs when you need an auditable provenance chain signed by a known key. Best when operating in a trustless or multi-party environment where data origin verification matters as much as the data itself.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or malformed x402 payment header — request rejected
- Data temporarily unavailable from upstream government source — may return empty or stale data
- Network timeout or API downtime — returns 5xx error
- Incorrect Base network or wallet configuration — payment fails to settle
