# Vextorium Transaction Status Lookup

> Vextorium Transaction Status Lookup is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-01).

Returns the status (pending/confirmed/failed), block number, confirmations, gas used, fee paid, created contract, and explorer link for a transaction hash on Base or Ethereum.

## Facts

- Endpoint: POST https://api.vextorium.com/estado-tx-pago?utm_source=zero.xyz
- Price: $0.004/call
- Payment: x402

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 vextorium-transaction-status-lookup-abbe5207 -d '<json body>'
```

Example prompt: Can you check the status of this Ethereum transaction — 0x4a3b...f9c2 — and tell me whether it's confirmed, how many confirmations it has, and how much gas was used?

## When to prefer this

Choose this endpoint when you need on-chain transaction status and metadata (confirmations, gas, fee, block) for a specific hash on Base or Ethereum, especially in an automated or agentic context where you also need the explorer link and contract creation details in a single structured response. Prefer it over manual block explorer lookups when building automated payment verification or transaction monitoring pipelines.

## Known failure modes

- Invalid or malformed transaction hash (not 0x + 64 hex) returns an error
- Hash not found on the specified network returns null fields or error
- Network not specified defaults or may error if required
- Rate limiting or payment failure returns HTTP 402 or 429
- RPC node latency may cause stale or slow results for very recent transactions

## How this service works

Transaction status by hash on Base or Ethereum: pending / confirmed / failed, block, confirmations, gas used, fee paid, created contract and explorer link.

## Output

Returns a JSON object with: network (red), transaction hash, sender (desde), recipient (hacia), block number (bloque), status string (estado: pending/confirmed/failed), gas used, ETH value transferred, commission in ETH, number of confirmations, created contract address (if any), number of emitted events, and a block explorer URL.
