# Saylor Innovations Data Desk – Stellar Address Validator

> Saylor Innovations Data Desk – Stellar Address Validator is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Validates a Stellar (XLM) address for safe sending: checks format, checksum, secret-seed exposure, funding status, memo requirements, live balance, OFAC sanctions screening, and returns a send verdict.

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 saylor-innovations-data-desk-stellar-address-validator-80ae99cd
```

Example prompt: Before I send XLM, can you validate the Stellar address GBYD7GVDQ4EBI3NZH2MHFVN6XJKBXN4KRQMFZKL5BWQH2XFZD6QT5Y — check the checksum, whether it's funded, if it needs a memo, and whether it passes OFAC sanctions screening?

## When to prefer this

Use this endpoint when you need a comprehensive pre-send safety check for Stellar (XLM) payments, combining format validation, on-chain status, live balance lookup, memo-required detection, secret-seed detection, and OFAC sanctions screening in a single call. Prefer this over generic address format checkers when compliance screening and live network data are required before executing a Stellar payment.

## Known failure modes

- Missing or malformed address parameter returns a validation error
- Submitting an empty string or non-Stellar address format returns format_valid: false
- OFAC or on-chain data source temporarily unavailable may result in partial results or error
- Network timeout when querying Stellar ledger for live balance
- Rate limiting or payment failure (x402) if USDC payment not processed correctly

## How this service works

Validate a Stellar address before sending: checksum, secret-seed detection, unfunded accounts, memo-required flag, live XLM balance, OFAC screening and a send verdict.

## Output

A JSON object containing: chain and chain_name (Stellar), the validated address, format_valid boolean, checksum result, network_match boolean, on_chain object with funding and balance data, sanctions screening result, a warnings array, overall verdict string, short summary, contextual note, and data source attribution.
