Endpoint
POSThttps://x402deploy.vercel.app/api/marketsWhen to prefer
Choose this endpoint when you need a ranked list of multiple cryptocurrency prices and 24h changes in a single call, especially when operating in a pay-per-request agent context with no API key setup. Prefer over full exchange APIs when you want lightweight market overview data without authentication overhead.
Side effects
- Invalid or unsupported quote currency (vs) returns empty or error response
- Payment not included or insufficient USDC causes 402 Payment Required response
- Limit value too high may return partial results or timeout
- Upstream price feed unavailable causes stale or missing data
