## 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 x402-hub-ton-fragment-api-b2a726db -d '<json body>'
```

Example prompt: Can you look up the username 'crypto' on TON Fragment and tell me its current price and auction status?

## When to prefer this

Use this endpoint when you need programmatic access to TON Fragment marketplace data — particularly Telegram username listings, auction statuses, or NFT ownership — without building a direct integration with the TON blockchain or Fragment platform. Ideal for agents operating in the TON/Telegram ecosystem that need lightweight per-query access paid via USDC micropayments on Base.

## Known failure modes

- Query returns no results if the username does not exist on Fragment
- Payment of ~$0.052 USDC required per call via x402 protocol; missing payment returns 402 error
- Upstream TON Fragment API downtime results in error response
- Malformed or empty query string may return error or empty data object
- Rate limiting or quota exceeded on upstream provider
