# Tanod chainpeek Transaction Lookup

> Tanod chainpeek Transaction Lookup is a paid API for AI agents from tanod.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

Fetches status, block number, confirmation count, sender/receiver, value, method ID, and fees (including Base L1 data fee) for a transaction on Ethereum or Base.

## Facts

- Endpoint: POST https://tanod.dev/v1/chain/tx?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IWoWDONtNfnt77WT7ehou

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tanod-chainpeek-transaction-lookup-2af21d0c -d '<json body>'
```

Example prompt: Can you look up transaction 0x4e3a...f2c1 on Base and tell me its status, how many confirmations it has, the from/to addresses, the value transferred, and the total fee including the L1 data fee?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
