## 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 kiteendpoints-ai-chain-check-beb49131 -d '<json body>'
```

Example prompt: Can you check whether this transaction hash 0xabc123... is confirmed on the Base chain and tell me its current status?

## When to prefer this

Use this endpoint when you need a quick, pay-per-use on-chain check without setting up your own blockchain node or RPC connection. It is well-suited for agents that only occasionally need to verify blockchain data and want to pay per query in USDC rather than subscribe to a dedicated blockchain data provider.

## Known failure modes

- Invalid or malformed address/hash returns an error result
- Unsupported chain identifier returns no data
- Network congestion may delay or fail real-time lookups
- Insufficient USDC balance for the $0.14 per-call fee blocks execution
- Rate limiting if too many requests are made in quick succession

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.

## Output

Returns a result object containing chain status data, validation outcome, or on-chain lookup information for the queried address or transaction hash. The response wraps the chain data in a result.data field.
