# AgentShelf Profile JSON-LD Extractor

> AgentShelf Profile JSON-LD Extractor is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Extracts all JSON-LD blocks from a public webpage or raw HTML and returns them as parsed JSON text, with SSRF protection.

## 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-profile-json-ld-extractor-84e4be6a -d '<json body>'
```

Example prompt: Can you pull all the JSON-LD structured data blocks from https://example.com/product/widget and give me the raw JSON?

## When to prefer this

Use this endpoint when you need ALL JSON-LD blocks from a page regardless of their @type, rather than a type-specific extractor (e.g. use the Product, Event, or Person sibling endpoints when you know the target type). Prefer this over the free sandbox /v1/sandbox/profile-jsonld endpoint when you need production reliability and paid-tier SLA. Choose this when your input is either a URL or raw HTML and you want SSRF-safe fetching handled server-side.

## Known failure modes

- URL is not publicly reachable or times out — returns error response
- URL targets a private/internal network address (SSRF protection blocks it) — returns 403 or error
- HTML input exceeds 200,000 character limit — validation error
- No JSON-LD blocks found on the page — returns empty array
- Malformed HTML that cannot be parsed — may return empty result or partial extraction
- URL is missing or too short (minLength 8) — validation error

## How this service works

Call when an agent needs every JSON-LD block as JSON text extracted from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld first.

## Output

Returns an array of JSON objects, each representing one JSON-LD block found in the page's <script type='application/ld+json'> tags, parsed from their raw JSON text form. Multiple blocks may be returned if the page contains several.
