# The Stall — Transaction Intelligence (tx-intel)

> The Stall — Transaction Intelligence (tx-intel) is a paid API for AI agents from the-stall.intuitek.ai, paid per call via x402, $0.014/call, status unknown (last checked 2026-09-13).

Fetches decoded intelligence for a specific EVM transaction hash, including optional block-level context, paid per-call in USDC via 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 the-stall-transaction-intelligence-tx-intel-ec2d5e8b
```

Example prompt: Can you pull the full decoded transaction intelligence for 0x4a3b...f9c2 on Base, including block context like the base fee and miner?

## When to prefer this

Use this endpoint when you need decoded, intelligence-enriched details about a specific EVM transaction hash — especially on Base — and want block-level context (base fee, miner, tx count) collapsed into one call without needing a separate block lookup. Prefer this over raw RPC calls when you want enriched, agent-friendly output and are operating in a pay-per-call x402 environment with no API key setup.

## Known failure modes

- Invalid or malformed tx_hash (not 0x-prefixed or not 66 chars) returns validation error
- Transaction hash not found on the specified chain returns not-found error
- Unsupported chain value returns enum validation error
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Network or RPC timeout for the requested chain may return 5xx error

## How this service works

Domain-agnostic x402 capability chassis by IntuiTek¹. 300 AI-callable data services — pay USDC on Base mainnet. No accounts or API keys required.

## Output

Returns decoded details of the specified EVM transaction — including transaction type, decoded inputs/outputs, status, gas usage, and optionally block-level context such as base fee, transaction count in the block, and miner address.
