# Soren Weather Oracle

> Soren Weather Oracle is a paid API for AI agents from soren.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Returns a signed, timestamped US National Weather Service station observation for a given coordinate, with SHA-256 and Ed25519 attestation of the exact NOAA data returned.

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 soren-weather-oracle-a4ff2fe3
```

Example prompt: Get me a signed, timestamped NOAA weather observation for Washington D.C. — lat 38.8894, lon -77.0352 — with the cryptographic attestation so I can prove what conditions were recorded right now.

## When to prefer this

Use this endpoint when you need not just the weather reading but cryptographic proof of what NOAA recorded — for insurance claims, smart contract triggers, legal disputes, compliance audits, or any scenario where a third party must independently verify conditions. Prefer it over a raw weather API when tamper-evidence, timestamping, and non-repudiation of the source data matter. It is US-only (NOAA coverage), so use an alternative for international locations.

## Known failure modes

- Coordinate outside US coverage area — NOAA does not provide data for non-US locations
- No nearby weather station — sparse coverage in remote US regions may return no observation
- NOAA upstream outage — if the National Weather Service is unavailable, the observation cannot be fetched
- Invalid lat/lon format — non-numeric or out-of-range coordinates return a validation error
- Payment failure — missing or insufficient x402 payment header results in a 402 response before data is returned

## How this service works

A signed, timestamped reading from the US National Weather Service for any US coordinate. Returns the latest station observation — temperature, dewpoint, humidity, wind, pressure, visibility — with a SHA-256 of the exact bytes NOAA returned and an Ed25519 signature over both. Use it to prove what the weather was recorded as at a moment. Verify with soren.com/oracle-key.json

## Output

A JSON object containing the latest NOAA station observation for the requested coordinate, including temperature, dewpoint, relative humidity, wind speed and direction, barometric pressure, and visibility. The response also includes a SHA-256 hash of the exact bytes returned by NOAA and an Ed25519 signature over the data and timestamp, enabling independent verification at soren.com/oracle-key.json.
