## 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 agentshelf-json-ld-recipe-extractor-165f02fb -d '<json body>'
```

Example prompt: Can you extract the structured recipe data from this page — https://www.seriouseats.com/the-best-slow-cooked-bolognese-sauce-recipe — and give me the ingredients, instructions, and cook time as JSON?

## When to prefer this

Use this endpoint when you need to extract machine-readable, structured recipe data (schema.org JSON-LD @type Recipe) from a public food or recipe webpage, either by providing the URL for server-side fetching or by supplying raw HTML directly. Prefer the free sandbox endpoint (/v1/sandbox/profile-jsonld-recipe) for testing. Choose this paid endpoint for production use when the sandbox is unavailable or rate-limited.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status, resulting in an error
- Page contains no JSON-LD @type Recipe markup, returning an empty or null result
- HTML input exceeds 200,000 character limit, causing a validation error
- URL or HTML contains malformed or incomplete JSON-LD, resulting in partial extraction
- SSRF-blocked URL (private IP ranges, localhost) rejected for security reasons
- Malformed URL input shorter than 8 characters rejected by schema validation

## How this service works

Call when an agent needs JSON-LD @type Recipe extracted from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-recipe first.

## Output

Returns a JSON-LD object conforming to schema.org @type Recipe, including fields such as recipe name, ingredients list, step-by-step instructions, cook time, prep time, serving size, and any other structured metadata embedded in the page's JSON-LD markup.
