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
A JSON report conforming to oix.machine-report/v1 containing: asset metadata (name, slug, market), cryptographic proof digests (reportDigest, sourceDigest), product details (offer description, price, settlement chain), and a decision object listing the requesting buyer context, up to 25 scored URL observations (each with URL, OIX evidence score 0-100, title, and evidence), plus total monitored record count and returned observation count.
Example use cases
E-commerce stock availability monitoring
“Check the OIX PageWatch Inventory for https://shop.example.com/product/widget and show me all observations with a score above 70 — I need to know if that page is still live and what's changed.”
Competitor website change detection
“Search the PageWatch Inventory for observations matching 'pricing' on https://competitor.io/pricing, limit to 5 results, and give me the report digest so I can prove what the page said.”
Automated availability proof for compliance
“Get me a full PageWatch Inventory report for https://docs.example.com/terms — I need the cryptographic source and report digests to prove the page was available and unchanged as of this check.”
Technical details
Endpoint
GEThttps://oix-autonomous-economy.fly.dev/api/x402/portfolio/pagewatch-inventoryWhen to prefer
Choose this endpoint when you need cryptographically-provable, scored observations about URL availability or content changes — especially when you need on-chain settlement proof (Base mainnet via x402) or when integrating with autonomous agent pipelines that require tamper-evident evidence of page state. Prefer over generic web scrapers when auditability and proof-of-observation matter.
Side effects
- Invalid or unreachable target URL returns empty observations or error
- minScore too high filters all results, returning empty observations array
- limit exceeds maximum of 25, rejected by schema validation
- Payment not settled via x402 on Base mainnet results in 402 response
- Target URL not in monitored inventory returns zero observations
- Query term matches no observations, returns empty list
