P0 Agent Economy Index – EVM Transaction Receipt Lookup
x402
P0 Agent Economy Index – EVM Transaction Receipt Lookup is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).
Fetches live on-chain transaction details (status, logs, gas, confirmations) for a given EVM transaction hash from a public node, returning a signed snapshot receipt.

How this service works
An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 listings are not covered.
Output
A JSON object containing the transaction's status (success/reverted/null), sender and recipient addresses, block number and hash, gas used, cumulative gas used, effective gas price, number of confirmations, decoded log events (up to 50), the public node that answered, an ISO 8601 timestamp of the reply, the latest block at query time, and an array of any fields the node did not return.
Example use cases
Verify a crypto payment on-chain
“I just sent a USDC payment and the tx hash is 0xa0dbae3236a486c4f7285206f416694bba403f95969dfa3d94a28e8f2538d9fd on Base — can you confirm it went through and how many confirmations it has?”
Debug a reverted smart contract call
“My transaction 0x3f9c1a2b4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f0a1b2c3d4e5f6a7b8c9d0e1f2a on Arbitrum seems to have failed — can you check its status and pull any logs so I can see what went wrong?”
Extract token transfer events from a tx
“Can you fetch all the logs from transaction 0xb1c2d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2 on Polygon and show me the token transfer topics and amounts?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/evm/receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, uncached EVM transaction data read directly from a public node — particularly for verifying payment receipts, checking confirmation counts, or extracting raw log events on Base, Ethereum, Arbitrum, Polygon, or Optimism. Prefer it over block explorer APIs when you want a machine-readable receipt with a snapshot hash and revision marker for auditability in agent-to-agent payment flows.
Side effects
- Invalid or malformed tx hash (must be 0x + 64 hex chars) returns a validation error
- Transaction not found on the specified chain returns null fields with errors array populated
- Unsupported chain name returns a schema validation error
- Public node unavailability may return partial nulls with the errors array listing missing fields
- Tx hash exists on a different chain than specified, causing not-found or wrong result
