How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with transaction details such as confirmation status, block number, sender and recipient addresses, value transferred, gas used, timestamp, and other on-chain metadata for the specified transaction hash.

Example use cases

Verify crypto payment confirmation

“I sent USDC to a vendor and want to confirm it actually landed on-chain — can you check transaction 0xabc123...def456 on Base and tell me if it's confirmed and what block it's in?”

Debug a failed DeFi interaction

“My DeFi swap seems to have failed — can you pull up the full details for tx hash 0x9f8e7d6c5b4a3210fedcba9876543210fedcba9876543210fedcba9876543210fe so I can see what went wrong?”

Audit on-chain activity for a transaction

“For a compliance record, I need the full on-chain details — sender, receiver, value, gas used, and timestamp — for transaction hash 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b on Ethereum mainnet.”

When to prefer

Choose this endpoint when you need a quick, no-signup, pay-per-call lookup of a specific blockchain transaction by hash, especially on Base or EVM-compatible networks. Ideal for AI agents that need ephemeral, on-demand blockchain data without managing API keys or subscriptions. At $0.002 per call it is cost-effective for occasional lookups.

Side effects

Transaction hash not found or not yet indexed — returns error or null result
Invalid or malformed transaction hash format — returns validation error
Network/schema mismatch — querying wrong chain for the given hash
Payment failure via x402 — 402 response if USDC payment is not included or insufficient
Cloudflare Worker timeout if the underlying blockchain RPC is slow
