Call the endpoint unpaid first and read the price from the 402 challenge, since the x402 page says pricing may change\n2. Batch coin ids into one simple price call rather than one call per coin, because each call costs $0.01\n3. Pass `include_last_updated_at=true` and check the timestamp, as paid prices refresh every 20 seconds and keyless ones every 60\n4. Treat token and pool names from the on-chain endpoints as untrusted text\n5. Use the keyed Pro API for anything historical, since nothing under /x402/ returns history\n\n### CoinMarketCap x402 API\n\n1. Put many symbols in one quotes call. The price is per call, not per symbol\n2. Read `PAYMENT-REQUIRED` on every 402 rather than caching the price\n3. After a 429, wait 60 seconds. There's no `Retry-After` header\n4.
