How this service works
x402 pay-per-call data endpoints for AI agents: multi-chain reads (Base, Ethereum, Arbitrum, Polygon) and Nigerian reference data. Format/reference validation only — no personal data, no identity-database lookup.
Output
Returns structured block data for the requested block on the specified EVM chain, including block number, hash, timestamp, transaction count or list, and other standard block fields as provided by the chain's RPC.
Example use cases
Monitor latest block height on Base
“Can you grab the latest block from the Base network and tell me its number and timestamp?”
Verify specific Ethereum block data
“Fetch block number 19500000 from Ethereum and show me its details.”
Cross-chain block comparison
“What's the latest block on Arbitrum? I want to compare block times across chains.”
Technical details
Endpoint
GEThttps://api.postandshare.net/v1/chain/block?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call on-chain block reads across Base, Ethereum, Arbitrum, or Polygon without managing your own RPC infrastructure. Ideal for AI agents that need occasional block lookups billed per-use via USDC micropayment rather than subscribing to a node provider.
Side effects
- Invalid or non-existent block number returns an error or empty result
- Unsupported network value (not base/ethereum/arbitrum/polygon) returns a validation error
- Network congestion or RPC downtime may cause timeouts
- Payment failure via x402 protocol returns HTTP 402
