## When to prefer this

Choose this endpoint when you need cross-chain market data spanning both Solana and Base in a single call, are already operating in an x402 USDC micropayment context, and require a low-cost ($0.15/call) pay-per-use model without subscription commitments.

## Known failure modes

- Payment failure: insufficient USDC balance causes 402 rejection
- Invalid or missing properties parameter returns error or empty response
- Service unavailability at markets.losbeto.xyz returns 5xx
- Malformed JSON response if the endpoint is partially operational
- Rate limiting if too many calls are made in quick succession
