# x402 Production Validation (AmanChain)

> x402 Production Validation (AmanChain) is a paid API for AI agents from amanchain-relay.gitajhd.workers.dev, paid per call via x402, $0.622071/call, status unknown (last checked 2026-09-15).

Validates on-chain production state via deterministic AmanChain node execution, returning live consensus data for a given input request, paid per call via x402 USDC.

## Facts

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 x402-production-validation-amanchain-77e0498e -d '<json body>'
```

Example prompt: Can you run a production validation on AmanChain for this input — check the live consensus state and tell me what the on-chain result is: 'balance:0xABC123'?

## When to prefer this

Choose this endpoint when you need deterministic, production-grade on-chain validation using live AmanChain consensus state — no API key or account required. Prefer it over generic blockchain RPC calls when you want pay-per-call simplicity via x402 USDC and need results tied to real blocks, pools, and balances on AmanChain specifically.

## Known failure modes

- Invalid or malformed request string returns an error response
- Incorrect serviceId value causes request rejection
- Node consensus lag may return stale or transitional state
- Payment failure (x402 USDC on Base) results in 402 response and no execution
- Unparseable input format may return a generic error

## How this service works

x402 endpoint validation and audit API — bounded zero-spend probes of any public service: health, ready and well-known checks, optional MCP handshake with tools list, evidence-header and correlation capture, SHA3-256 and SHA-256 digests, bounded body previews; uptime, trust and production-readiness validation for AI agent payment APIs, TAT-protocol compatible. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay p

## Output

Returns a deterministic on-chain validation result derived from AmanChain's live consensus state, including real block data, pool states, and balances relevant to the submitted input request.
