How this service works
Fast, low-cost Base data for autonomous agents. No API keys, no subscriptions; pay per call with USDC over x402.
Output
Returns a JSON object containing the full block data object, a boolean 'found' flag indicating whether the block exists, the network identifier (eip155:8453 for Base mainnet), and the resolved block number.
Example use cases
Verify transaction block existence
“I need to confirm that block 35999500 exists on Base mainnet — can you fetch it and tell me if it was found?”
On-chain audit trail lookup
“Pull the full block data for Base block number 36000000 so I can audit what happened at that point in the chain.”
Historical block research
“I'm researching Base L2 activity — can you retrieve the block at height 30000000 and give me its details?”
Technical details
Endpoint
POSThttps://api.mach.gallery/api/base/block?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch a specific Base mainnet block by number or hash without setting up your own RPC node or managing API keys. It is ideal for lightweight, pay-per-call agent workflows that need occasional block lookups without a subscription. Prefer alternatives (e.g., a full Ethereum node or Alchemy/Infura) if you need high-volume batch queries, real-time streaming, or data from chains other than Base (eip155:8453).
Side effects
- Block not found: returns found=false if the block number or hash does not exist on Base
- Invalid input: non-numeric string or negative integer may return an error
- Payment failure: x402 micropayment of $0.005 USDC must succeed before the response is returned
- Network issues: upstream Base node unavailability may cause timeouts or errors
