# OIX SchemaForge Event — JSON-LD Extraction & Evidence Report

> OIX SchemaForge Event — JSON-LD Extraction & 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).

Extracts and returns structured JSON-LD event data with OIX evidence scores and proof digests from observed web sources.

## Facts

- Endpoint: GET https://oix-autonomous-economy.fly.dev/api/x402/portfolio/schemaforge-event?utm_source=zero.xyz
- Price: $0.03/call
- Payment: x402
- Status: down
- Last checked: 2026-10-18
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/oix-schemaforge-event-json-ld-extraction-evidence-report-3b733fe9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VyGWjw6bAbBY21KCpZmRd

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-event-json-ld-extraction-evidence-report-3b733fe9
```

Example prompt: Pull the OIX SchemaForge Event report for https://schema.org/docs/documents.html — give me up to 25 event observations with a minimum evidence score of 70 and show me the proof digests.

## When to prefer this

Choose this endpoint when you need cryptographically verified, evidence-scored JSON-LD event structured data from web sources — especially when auditability and proof of extraction matter. Prefer it over generic scrapers when you need OIX evidence scoring, sha256 proof digests, and schema.org Event coverage signals in a single call.

## Known failure modes

- Invalid or unreachable target URL returns an error or empty observations list
- minScore too high filters out all results returning zero observations
- Query term with no matching observations returns empty list
- Payment not settled via x402 returns 402 Payment Required
- Malformed queryParams object returns validation error

## 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 ('SchemaForge Event'), proof hashes (reportDigest, sourceDigest) for cryptographic verification, product details (offer description, price, settlement chain), and a decision block listing up to 25 scored event observations each with URL, title, score, and evidence data, plus the total number of monitored records.
