# Agent Weather Pay Radar (Paycheck)

> Agent Weather Pay Radar (Paycheck) is a paid API for AI agents from api.agentweather.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-18).

Reads the x402 payment header of an XRPL endpoint without paying and returns a full pre-payment assessment of its validity, pricing, network, asset, and payTo account health.

## Facts

- Endpoint: GET https://api.agentweather.io/v1/paycheck?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-18
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agent-weather-pay-radar-paycheck-d2a15554
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IGpzQ_dOEXVQtolVn0W6D

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 agent-weather-pay-radar-paycheck-d2a15554
```

Example prompt: Before I pay anything, check the x402 payment requirements for https://api.example.com/v1/data — is the payTo XRPL account activated, does it have a valid RLUSD trust line, and what's the price?

## When to prefer this

Use this endpoint when you need to vet an x402-gated API before committing to payment — especially when the payTo XRPL address is unfamiliar, you want to confirm RLUSD trust line setup, or you need a human-readable verdict on whether the endpoint is safe and correctly configured. Prefer this over blindly sending payment when due diligence on merchant account health is required.

## Known failure modes

- Target URL does not respond with a 402 status — returns an error or empty reading
- XRPL account lookup fails due to network issues or unrecognized address format
- Provided URL is malformed or missing scheme — returns validation error
- Target endpoint is behind a firewall or rate-limits probe requests — incomplete readings
- Asset issuer does not match known RLUSD issuer — flagged as unknown or suspicious

## How this service works

Pay Radar: pre-payment readings for an XRPL x402 endpoint (GET /v1/paycheck?url={endpoint}; alias /v1/payradar). Reads its 402 without paying and lists raw readings first: x402 shape, network, asset (RLUSD by issuer), the payTo account on the XRP Ledger (exists, activated, balance, trust line, age)…

## Output

Returns a structured verdict (e.g. safe/unsafe/warning), a list of human-readable reasons, a full breakdown of checks performed (x402 shape validity, network, asset type, RLUSD issuer match, payTo account existence, activation status, balance, trust line, account age), and a recommended payment rail.
