How this service works
Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents
Output
Returns a JSON object indicating the network name (e.g. 'base'), the observed timestamp of the transaction or block, and confirmation status details as of the observation time.
Example use cases
Verify payment finality before fulfillment
“I just sent a USDC payment on the Base network — can you check whether that transaction is fully confirmed on-chain before I ship the order?”
Monitor agent-initiated on-chain transaction
“My autonomous agent just submitted a transaction to Base. Can you keep checking its confirmation status and let me know once it's finalized?”
Debug a stuck or pending transaction
“I submitted a transaction on Base a while ago and I'm not sure if it went through. Can you look up its confirmation status and tell me when it was last observed on-chain?”
Technical details
Endpoint
GEThttps://cryptoshark.duckdns.org/chain/confirmation-status?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost ($0.001 USDC), real-time lookup of on-chain confirmation status specifically on the Base network, and you are operating within an x402-compatible agent payment workflow. Prefer it over heavier blockchain explorer APIs when you only need confirmation status rather than full transaction details.
Side effects
- Missing or invalid transaction/block identifier returns an error or empty result
- Transaction not yet indexed returns unconfirmed or null status
- Network unavailability or node lag may return stale observation timestamps
- Malformed properties input returns a 400-level error
- Rate limiting or payment failure via x402 returns a 402 Payment Required response
