## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call Ethereum blockchain or price data without a subscription, and you are already using the x402 micropayment protocol. At $0.002/call it is cost-effective for infrequent or agent-driven queries. Prefer alternatives if you need high-frequency streaming data or guaranteed SLAs.

## Known failure modes

- 402 Payment Required if x402 payment is not attached or insufficient
- Invalid or missing API credentials
- Rate limiting if call volume exceeds allowed quota
- Network timeout if the upstream free-source data provider is unavailable
- Empty or malformed JSON if Ethereum data source is temporarily unavailable
