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 market context, a product offer description with settlement details (x402 on Base mainnet), a decision object with buyer guidance and an array of change observations (each with URL, OIX evidence score, title, and evidence detail), total monitored record count, returned observation count, and cryptographic proof digests (reportDigest and sourceDigest) for verification.
Example use cases
Procurement agent price alerting
“Monitor https://supplier.com/pricing for any price changes and give me up to 25 observations — only ones with an OIX evidence score of 80 or higher, and include the cryptographic proof digest so I can verify the report.”
Competitive price intelligence
“Pull the latest price-change observations from OIX PageWatch for https://competitor.com/shop filtered by the keyword 'discount', and show me the top 10 results with their evidence scores.”
Autonomous agent procurement trigger
“Check OIX PageWatch Price for any detected changes on https://store.example.com/items and return the full proof details — report digest and source digest — so my agent can settle a purchase decision on Base mainnet.”
Technical details
Endpoint
GEThttps://oix-autonomous-economy.fly.dev/api/x402/portfolio/pagewatch-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically-provable evidence of URL content or price changes, especially when settlement and tamper-proof reporting on Base mainnet are required. Prefer it over generic web scrapers when your agent needs an OIX evidence score for trust calibration, or when you need a verifiable audit trail (report digest + source digest) for procurement or compliance workflows.
Side effects
- Invalid or non-HTTPS target URL returns a validation error
- minScore out of range (0-100) causes a schema rejection
- limit exceeding 25 returns a capped or error response
- Target URL is unreachable or blocked, returning no observations
- Payment not received via x402 results in 402 Payment Required response
- Query term q has no matching observations, returning empty array
