## When to prefer this

Choose this endpoint when you need global crypto market summary data without managing API keys or subscriptions — ideal for agents that run infrequently and want pay-as-you-go access. Prefer it over key-based alternatives when operating in a keyless or wallet-native environment using the x402 micropayment protocol on Base.

## Known failure modes

- Payment rejected or insufficient USDC balance — x402 payment failure, request blocked
- Upstream data source unavailable — fallback sources exhausted, stale or missing data returned
- Rate limit on upstream provider — potential delay or degraded data quality
- Malformed x402 payment header — 402 response with no data
- Network timeout at edge — retry recommended
