## How to call it through Zero

```sh
zero fetch --capability rotary-agency-blockchain-data-api-74d190d1
```

Example prompt: Can you look up the on-chain details for Ethereum wallet address 0xAbC123... using the Rotary Agency blockchain data API?

## When to prefer this

Choose this endpoint when you need quick, low-cost ($0.002/call) access to raw blockchain data without relying on a proxied or marked-up aggregator. It is well-suited for agents that need on-chain lookups (transactions, addresses, blocks) and want direct free-source data with no intermediary markup. Prefer alternatives if you need guaranteed SLAs, websocket streaming, or multi-chain batch queries.

## Known failure modes

- Missing or invalid query parameters return an error or empty response
- Unsupported blockchain network returns a 400 or null result
- Payment not received (x402 protocol failure) blocks the response
- Rate limiting or throttling if too many calls are made rapidly
- Stale or delayed on-chain data if the upstream free-source is lagging
