How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

Output

Returns transaction status (pending, success, failed), block number, confirmation count, from and to addresses, transferred value, method ID (for contract interactions), gas fee, and the Base L1 data fee where applicable — all in a single read-only response.

Example use cases

Confirm incoming crypto payment

“I just received a payment — can you check if transaction 0xabc123...def456 on Ethereum is confirmed and show me the sender address and value transferred?”

Audit gas fees on Base transaction

“What was the total fee paid for transaction 0x9f8e7d...6c5b4a on Base, including the L1 data fee? I want to reconcile my gas costs.”

Identify contract method called

“Can you inspect transaction 0x1a2b3c...4d5e6f on Ethereum and tell me what method ID was called, which block it landed in, and its current confirmation count?”

When to prefer

Choose this endpoint when you need comprehensive transaction details — status, addresses, value, method ID, and fees (especially Base L1 data fees) — in a single call on Ethereum or Base. Prefer it over raw RPC calls when you want a clean, structured response without managing node infrastructure. Ideal for agents that need to verify payments, audit fees, or inspect contract interactions on these two chains specifically.

Side effects

Invalid or malformed transaction hash returns a validation error
Transaction hash not found on the specified chain returns a not-found error
Wrong chain specified (e.g. hash exists on Ethereum but Base was requested) returns no result
Network or RPC issues may cause transient failures
Payment failure (x402 protocol) prevents the request from being processed
