## When to prefer this

Choose this endpoint when you need on-chain Solana block data by block ID via the Blockchain.com Explorer Gateway, especially in x402 payment-enabled agent workflows. Prefer this over general RPC endpoints when you want a simple REST interface with pay-per-call pricing rather than managing a full Solana JSON-RPC connection.

## Known failure modes

- Block ID not found or not yet finalized — returns error or empty response
- Invalid block ID format (non-integer or out-of-range) — returns validation error
- Network parameter mismatch (e.g. wrong chain specified) — may return incorrect or no data
- Service unavailable or rate-limited — returns HTTP 402 or 5xx error
- Block too recent and not yet indexed — may return empty result
