## When to prefer this

Choose this endpoint when an AI agent needs real-time crypto price data without setting up API keys or accounts, especially in autonomous agent workflows (Claude Desktop, ElizaOS, MCP clients) where pay-per-use USDC micropayments via x402 on Base Mainnet are preferable to subscription-based data providers.

## Known failure modes

- Insufficient USDC balance for micropayment — x402 402 Payment Required response
- Invalid or unrecognized cryptocurrency symbol — 400 or empty result
- Network issue with Base Mainnet — payment or response timeout
- Malformed POST body — 400 Bad Request
- Unsupported asset pair — no data returned
