# ChainRead Transaction Status

> ChainRead Transaction Status is a paid API for AI agents from chainread.imac2014ville.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Looks up the status, gas used, confirmations, and fee of an EVM transaction by hash on Base or Ethereum mainnet

## Facts

- Endpoint: GET https://chainread.imac2014ville.workers.dev/tx-status?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/chainread-transaction-status-f0f4173e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ga_Aks5t8YyMADXJDqVrx

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 chainread-transaction-status-f0f4173e
```

Example prompt: Can you check whether this Base transaction went through and how many confirmations it has: 0x3a1b2c4d5e6f7890abcdef1234567890abcdef1234567890abcdef1234567890ab?

## When to prefer this

Use this endpoint when you need a fast, cheap, no-API-key way to check the status, confirmation count, or gas cost of a specific EVM transaction on Base or Ethereum. Ideal for AI agents that need to verify transaction finality or fee reporting without setting up a full node connection or managing RPC API keys. Pay-per-call USDC pricing via x402 makes it suitable for lightweight or infrequent lookups.

## Known failure modes

- Invalid or malformed transaction hash returns an error response
- Transaction not found on the specified chain (e.g. looking up a Base tx on Ethereum)
- Network or RPC node timeout causing a failed lookup
- Missing required hash query parameter returns a 400-level error
- Payment failure via x402 if USDC balance on Base is insufficient

## How this service works

Cheap EVM read utilities for AI agents on Base and Ethereum mainnet: gas and fees, blocks, balances, ERC-20 metadata, contract inspection, transaction status, ENS/Basename resolution, bulk balances. No API key: pay USDC on Base per call via x402.

## Output

Returns a JSON object with: ok (boolean), chain (base or ethereum), status (success/failed/pending), gasUsed (integer), confirmations (integer), feeEth (ETH amount), and feeUsd (USD equivalent of the transaction fee).
