# XRPL Payment Verifier (CoCo Launch Lab)

> XRPL Payment Verifier (CoCo Launch Lab) is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.0014/call, status unknown (last checked 2026-10-19).

Verifies that a specific XRP Ledger transaction exists and was successfully validated, optionally checking amount, currency, issuer, destination, and destination tag.

## 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 xrpl-payment-verifier-coco-launch-lab-fe59850a
```

Example prompt: Can you verify that XRPL transaction hash A1B2C3D4E5F6... was found and validated on the XRP Ledger, destined for rXXXXXXXXXXXXXXXXXXXXXXXXXXX?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call verification of an XRPL transaction by hash without running your own XRPL node. Ideal for confirming XRP or issued-currency payments in agent workflows, e-commerce gating, or access control before delivering a service. Prefer this over generic blockchain explorers when you need a structured, machine-readable boolean response suitable for automated decision-making.

## Known failure modes

- Transaction hash not found on ledger — returns found: false
- Invalid or malformed transaction hash (too long, wrong format) — validation error
- Amount or destination mismatch if optional params provided — may return found: true but validated: false
- XRPL node connectivity issues — potential timeout or server error
- Destination tag out of range (must be 0–4294967295) — input validation failure

## Output

A JSON object with boolean fields: 'found' (whether the transaction exists on the ledger), 'validated' (whether the transaction is in a validated ledger), and 'ok' (overall success of the API call). Returns found: false if the tx hash is not located.
