# OIX SchemaForge Product — JSON-LD Evidence Report

> OIX SchemaForge Product — JSON-LD Evidence Report is a paid API for AI agents from oix-autonomous-economy.fly.dev, paid per call via x402, $0.03/call, status down (last checked 2026-10-18).

Fetches an evidence-backed JSON-LD extraction and scoring report for the SchemaForge Product asset, including market signals, proof digests, and observations from monitored sources.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 oix-schemaforge-product-json-ld-evidence-report-1920b3de
```

Example prompt: Pull the OIX SchemaForge evidence report for https://example.com/product — I want to see JSON-LD extraction observations with a minimum score of 70, up to 10 results, filtered by the term 'offer'.

## When to prefer this

Choose this endpoint when you need cryptographically provable, evidence-scored JSON-LD extraction from a product or offer URL — especially when shopping or pricing agents need verifiable schema.org structured data with audit trails. Prefer this over generic scraping tools when proof digests and OIX evidence scores are required for downstream trust or compliance workflows.

## Known failure modes

- Invalid or unreachable target URL returns an error or empty observations
- minScore too high filters out all results, returning empty observation list
- Query term finds no matching observations against monitored sources
- Payment of 0.03 USDC not fulfilled — endpoint returns 402 Payment Required
- limit parameter outside 1-25 range causes validation error
- Non-GET/HEAD/DELETE HTTP method rejected by schema validation

## How this service works

Package any earning logic as an autonomous asset. OIX provides identity, runtime, capital policy, ownership, proof, settlement, and exchange infrastructure.

## Output

Returns a JSON object containing: the asset name and slug, cryptographic proof digests (report and source SHA-256), product offer details and settlement info, a buyer recommendation label, a list of scored observations (each with URL, title, evidence score, and evidence object), total monitored record count, and returned observation count — all under the oix.machine-report/v1 protocol.
