## 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 mekong-trade-intel-request-metadata-echo-api-a60d9792 -d '<json body>'
```

Example prompt: Can you call the Mekong Trade Intel metadata echo endpoint and tell me what IP address and user-agent you're sending requests from, along with the current server timestamp?

## When to prefer this

Choose this endpoint when you need to introspect the actual HTTP metadata your AI agent transmits during outbound calls — particularly useful for determining egress IP for whitelisting, verifying user-agent strings, or checking server-side timestamps. Prefer this over a standalone IP lookup endpoint when you also need user-agent and timestamp data in one call.

## Known failure modes

- Payment failure if USDC balance on Base is insufficient — returns 402 Payment Required
- Malformed POST body not matching required schema returns 400 Bad Request
- Network timeout if the agent's HTTP stack is misconfigured
- Server unavailability returns 503

## How this service works

Request metadata echo API for AI agents — returns your IP, user-agent, timestamp and server time, $0.001 USDC on Base. Debug agent HTTP stacks.

## Output

A JSON object containing the caller's egress IP address, the HTTP user-agent string sent with the request, the request arrival timestamp, and the server's current time — useful for diagnosing agent network configuration and HTTP stack behavior.
