# Clink Forge Station Monthly Temperature

> Clink Forge Station Monthly Temperature is a paid API for AI agents from api.clinkforge.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns government-sourced monthly temperature data for a weather station, signed with cryptographic provenance, paid per-call via x402/USDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability clink-forge-station-monthly-temperature-f6accc5f
```

Example prompt: Pull the monthly temperature records for weather station USC00010008 from January 2020 to December 2022 — I need the data with its cryptographic provenance so I can verify it came from an official government source.

## When to prefer this

Choose this endpoint when you need government-sourced monthly temperature data for a specific weather station with cryptographic provenance and attestation — particularly when data integrity verification, audit trails, or citation of official sources is required. Prefer this over generic weather APIs when the authenticity and chain-of-custody of the data must be machine-verifiable, and when you want pay-per-call access without API key registration.

## Known failure modes

- Payment failure or insufficient USDC balance returns 402 Payment Required
- Invalid or unknown station entity ID returns empty data array or 400 error
- Date range outside available data returns empty rows
- Malformed start/end date strings exceeding 12 characters return validation error
- Network timeout for government data source returns 503 or delayed response

## 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 an array of monthly temperature data rows keyed by record ID, the product name and version, a provenance chain including SHA-256 hash, source government URL, observing authority, and observation timestamp, a cryptographic attestation with signature and result digest, and a payment receipt showing USDC amount and on-chain settlement reference.
