Technical details
Endpoint
GEThttps://skills.onesource.io/api/chain/block-numberWhen to prefer
Use this endpoint when you need the current Ethereum (or EVM-compatible) block height in real time — for example, to check chain sync status, compute block lag, anchor timestamps, or verify if a transaction has been mined. Prefer this over general blockchain explorers when you need a lightweight, programmatic, pay-per-call RPC-backed result without API key management.
Side effects
- Unsupported network value returns validation error
- RPC node temporarily unavailable returns 5xx error
- Rate limiting or payment failure returns 402/429
- Malformed query parameter returns 400 bad request
