# AgentForge Payment Flow Verification Ping

> AgentForge Payment Flow Verification Ping is a paid API for AI agents from agentforge-taupe.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Confirms that an agent's wallet and x402 payment channel are working correctly by executing a real $0.001 USDC microtransaction against a test endpoint before the agent calls production services.

## Facts

- Endpoint: GET https://agentforge-taupe.vercel.app/v1/ping?utm_source=zero.xyz
- Price: $0.001/call

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 agentforge-payment-flow-verification-ping-4426f3a9
```

Example prompt: Before I start calling paid AgentForge endpoints, can you ping the AgentForge payment verification endpoint to confirm my wallet and x402 payment channel are working correctly?

## When to prefer this

Use this endpoint as a first step whenever setting up a new agent wallet or x402 payment integration, or when debugging payment failures before calling more expensive production endpoints. At $0.001 USDC it is the cheapest possible real-money confirmation that the full payment pipeline — wallet, signing, x402 protocol, and endpoint delivery — is functioning end-to-end. Prefer this over manual wallet checks or unit tests because it exercises the actual live payment flow.

## Known failure modes

- Insufficient USDC balance in agent wallet — payment rejected before endpoint is reached
- Misconfigured x402 payment header — 402 Payment Required error returned without processing
- Invalid or missing wallet credentials — authentication or signing failure
- Network or Vercel cold-start latency causing timeout on first call
- Malformed request method (non-GET) returning 405 Method Not Allowed

## How this service works

Payment flow verification for agents integrating x402: confirms your wallet and payment channel work before you spend on a real endpoint. Category: infra.

## Output

Returns a JSON object with a status string (e.g. 'ok'), a human-readable message confirming the payment and ping succeeded, and an ISO 8601 timestamp of when the response was generated. A successful response confirms the agent's wallet signed and broadcast the $0.001 USDC payment correctly through the x402 protocol.
