## 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 agenttoll-openrouter-models-lookup-11f53ae9 -d '<json body>'
```

Example prompt: Can you pull the current list of AI models available on OpenRouter so I can see which ones I can route requests to?

## When to prefer this

Use this endpoint when an AI agent needs a programmatic, pay-per-call lookup of the OpenRouter model catalog without managing OpenRouter API credentials directly, or when operating in an x402-enabled payment environment on Base and wanting to consolidate data tool access through a single provider.

## Known failure modes

- Empty data array returned if OpenRouter API is unavailable or returns no models
- Payment failure if USDC balance on Base is insufficient
- HTTP 402 if x402 payment protocol handshake fails
- Stale or incomplete model list if upstream OpenRouter data is cached or delayed

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns a JSON object with a 'data' array containing the list of AI models available on OpenRouter, and a 'success' boolean indicating whether the request succeeded.
