# Weather Consensus Endpoint (x402-seller)

> Weather Consensus Endpoint (x402-seller) is a paid API for AI agents from x402-seller-m8nx.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns a blended consensus temperature at a lat/lon point by fusing multiple weather sources (Open-Meteo, NOAA-NWS, 7timer) with agreement scoring, paid per-call via x402 USDC microtransaction.

## 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 weather-consensus-endpoint-x402-seller-32b8fe5d
```

Example prompt: What's the consensus temperature right now at latitude 40.71, longitude -74.01 — blended from multiple weather sources with an agreement score?

## When to prefer this

Choose this endpoint when you need a single, reliable temperature reading at a specific coordinate and want automatic multi-source fusion with an agreement quality signal — rather than calling Open-Meteo, NOAA-NWS, and 7timer separately and reconciling them yourself. Useful when agent reliability matters more than raw cost, since one call replaces three API integrations.

## Known failure modes

- One or more upstream sources may timeout, reducing sourceCount and widening stdevC
- Payment failure via x402 returns 402 with no data
- Invalid or out-of-range lat/lon may return a validation error
- Low agreementScore indicates sources diverge significantly — blendedTempC may be unreliable
- All sources failing returns no consensus data

## How this service works

Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).

## Output

A JSON object containing the query coordinates, an array of per-source temperature readings (each with source name and tempC, or an error/timeout flag), and a consensus object with blendedTempC, stdevC, sourceCount, and agreementScore (0-100).
