## 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 toolvet-api-recommender-579c59dc
```

Example prompt: Search ToolVet for the best x402 API to get the current price of ETH — I want something with a high trust score and no more than $0.005 per call on Base mainnet.

## When to prefer this

Use this endpoint when an AI agent needs to dynamically discover the best-fit paid API or MCP server for a task at runtime, especially when you want trust signals, uptime data, and pricing context before committing to a call. Prefer this over hardcoding an API choice when reliability, cost, and vetting matter, or when the optimal tool for a task may change over time.

## Known failure modes

- No matching APIs found for the given task — returns empty picks array
- Invalid or unsupported CAIP-2 network identifier — may return no results or an error
- max_price too restrictive — filters out all candidates, returning empty list
- Malformed task string — vague or extremely short queries may yield irrelevant recommendations
- Rate limiting or payment failure if x402 payment is not processed correctly

## Output

A JSON object containing a ranked list of picks, each with the API name, URL, trust score, pricing (USD, asset, atomic units, network), 30-day uptime and latency stats, call volume, category, provider name, and a ready-to-use how_to_call block with method and example input. An alternatives array is also returned for secondary options.
