## When to prefer this

Choose this endpoint when you need cryptocurrency historical price data and prefer a pay-per-call model over subscription APIs, especially in agent workflows using x402 micropayments on Base. Suitable for lightweight, infrequent lookups where avoiding API key management matters. Not ideal for high-frequency or bulk data ingestion due to per-call pricing.

## Known failure modes

- Invalid or unrecognized cryptocurrency symbol returns an error
- Date range exceeds available historical data
- Missing required query parameters results in a 400-level error
- Payment failure via x402 returns a 402 Payment Required response
- Rate limiting or server overload returns a 429 or 503 error
