Technical details
Endpoint
GEThttps://x402tap.com/api/crypto-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, lightweight price check with 24h change and market cap for one or more cryptocurrencies and cost-per-call efficiency matters. Prefer this over the sibling 'x402 Crypto Market Data' endpoint when you don't need extended data like ATH, 24h high/low, or trading volume — this endpoint is simpler and cheaper for basic price lookups.
Side effects
- Invalid or unrecognized CoinGecko coin ID returns an error or empty result
- Unsupported quote currency may return an error or fall back to USD
- Payment failure (insufficient USDC) results in a 402 response
- Rate limiting or upstream CoinGecko unavailability may cause transient errors
- Missing required 'ids' query parameter results in a validation error
