## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call real-time spot price for one or more cryptocurrency pairs without a subscription. Especially useful for AI agents that need occasional price checks (not high-frequency streaming), support batch lookups of up to 25 pairs in a single call, and operate in x402 micropayment environments. Prefer this over subscription-based market data APIs when cost-per-call economics favor low-volume or on-demand pricing.

## Known failure modes

- Invalid or unsupported pair symbol returns an error or empty result
- Exceeding 25 pairs in a batch request may result in an error
- Missing required query parameters (pair, pairs, or symbol) may return a validation error
- Network or upstream data source outage may cause stale or failed responses
- Payment failure (x402 protocol) blocks the request entirely
