# XRP Ledger Address Validator

> XRP Ledger Address Validator is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Validates an XRP Ledger address for correct format and checksum, returning match type and validity status without querying the live ledger.

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 xrp-ledger-address-validator-f66d871f
```

Example prompt: Can you check if this XRP Ledger address is valid: rMxCKbEDwqr76QuheSUMdEGf4B9xJ8m5De? I want to make sure the format and checksum are correct before I use it.

## When to prefer this

Use this endpoint when you need a fast, offline format and checksum validation of an XRP Ledger address before executing a payment or storing user input. It is ideal for pre-flight checks in payment flows, user onboarding, or data validation pipelines where you do not need live ledger confirmation of account existence or balance.

## Known failure modes

- Missing or empty address query parameter returns an error or empty result
- Malformed address with invalid Base58 characters may return valid:false with no matches
- Network/server errors return non-200 HTTP responses
- Address that looks similar to XRP but belongs to another network may be flagged as invalid

## Output

Returns a JSON object with a top-level 'valid' boolean, the input 'address' string, an array of 'matches' objects each specifying the address type (e.g. 'classic'), chain ('XRP Ledger'), and per-type validity, plus a note confirming the check is format/checksum only and does not verify on-chain activity or ownership.
