Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/block/:chainWhen to prefer
Use this endpoint when you need a quick snapshot of the current chain head — block number, timestamp, hash, TX count, gas used — for Base, Ethereum, Arbitrum, or Polygon without needing full node access. Ideal for agents that need to anchor time-sensitive on-chain queries, verify block progression, or check network liveness.
Side effects
- Unsupported chain value returns an error — only 'base', 'ethereum', 'arbitrum', 'polygon' are valid
- Missing 'chain' query parameter causes a 400 bad request
- Node or data provider downtime may return a 503 or timeout
- Payment failure (x402) blocks the request if USDC balance is insufficient
