# Orbit Chain Reads: EVM Transaction Status

> Orbit Chain Reads: EVM Transaction Status is a paid API for AI agents from orbit-chain.orbit-builder.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

Looks up the status and details of an EVM transaction hash on Base, Ethereum, Arbitrum, Optimism, or Polygon

## Facts

- Endpoint: GET https://orbit-chain.orbit-builder.workers.dev/v1/tx?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/orbit-chain-reads-evm-transaction-status-f6228183
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_gqh-BRw-qF5wCr851DMxa

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 orbit-chain-reads-evm-transaction-status-f6228183
```

Example prompt: Can you check whether transaction 0x0b31... on Base went through successfully, and tell me the block, confirmations, gas used, and fee paid?

## When to prefer this

Use this endpoint when you need to quickly look up the status and on-chain details of a specific EVM transaction hash across Base, Ethereum, Arbitrum, Optimism, or Polygon. It is ideal for confirming payment settlement, debugging failed transactions, or verifying smart contract deployments. Prefer this over block explorer UIs or full node queries when you need a structured, programmatic response in an agent workflow at low cost ($0.001 USDC per call).

## Known failure modes

- Unknown or invalid transaction hash returns 404 with no charge
- Unsupported chain name returns an error
- Malformed hash (wrong length or missing 0x prefix) causes a validation error
- Transaction may show as pending if not yet mined
- Network connectivity issues to the target chain RPC may cause timeouts

## How this service works

Live EVM chain reads for agents across Base, Ethereum, Arbitrum, Optimism and Polygon: gas fees, wallet balances (native + USDC), transaction status, ERC-20 metadata and ENS resolution. Every answer is read from public RPC nodes at call time. $0.001 per call. By orbit-builder.

## Output

Returns a JSON object with the transaction's status (success/failed/pending), block number, confirmation count, sender address (from), recipient address (to), value transferred in native coin, nonce, gas used, effective gas price in gwei, fee paid in native coin, number of logs emitted, and any contract address created. Returns 404 (not charged) if the hash is unknown.
