Endpoint
POSThttps://api.fastapi.online/coin-details?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need detailed metadata for a single specific cryptocurrency identified by a known coin ID, and you want a pay-per-call model without signup. Prefer this over subscription APIs for low-frequency lookups or when crypto micropayment (USDC via x402) is the preferred billing method.
Side effects
- Invalid or unrecognized coin ID returns an error or empty result
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Network or server unavailability results in a timeout or 5xx error
- Coin ID format mismatch (e.g. wrong casing or slug style) may return no data
