# Ren API - Seed-Oil-Free Restaurant List

> Ren API - Seed-Oil-Free Restaurant List is a paid API for AI agents from ren-api-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

## 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 ren-api-seed-oil-free-restaurant-list-80ed90a8
```

Example prompt: Can you show me a list of seed-oil-free restaurants in Montrose / Heights with a clean verdict?

## When to prefer this

Use this endpoint when you need a quick, filtered list of seed-oil-free or health-conscious restaurants without detailed data. Prefer this over a full detail endpoint when you only need names, verdicts, and neighborhoods for browsing or routing purposes. Best for agents answering questions like 'which restaurants near me avoid seed oils?'

## Known failure modes

- No restaurants match the given verdict/neighborhood combination — returns empty array
- Invalid query parameter values may be ignored or return unfiltered results
- Payment failure (x402) if USDC is not available or transaction fails
- Service unavailable if Railway.app hosting is down

## How this service works

Returns a lightweight restaurant list with name, verdict, and neighborhood.

## Output

An array of restaurant objects, each containing a name (string), verdict (string, e.g. 'clean'), and neighborhood (string). The list is lightweight and pre-filtered based on the query parameters provided.
