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 metadata (name, slug, market), a cryptographic proof (report and source SHA-256 digests), product offer details (price, settlement), and a decision block listing scored observations for the target URL — each observation includes the URL, an OIX evidence score (0–100), a title, and evidence data — along with total monitored record count and number of returned observations.
Example use cases
Privacy policy change audit
“Has OpenAI's privacy policy changed recently? Use OIX PageWatch to check https://openai.com/policies/privacy-policy for any updates and give me the top 10 observations with a score above 60.”
Vendor terms compliance monitoring
“I need to verify whether Stripe's terms of service at https://stripe.com/legal/ssa have been modified — pull the latest PageWatch observations with cryptographic proof so I can log it for our compliance records.”
Regulatory document tracking
“Watch https://www.sec.gov/rules/final.shtml for any new rule changes — search for 'disclosure' and return up to 20 results with an evidence score of at least 40.”
Technical details
Endpoint
GEThttps://oix-autonomous-economy.fly.dev/api/x402/portfolio/pagewatch-policyWhen to prefer
Choose this endpoint when you need cryptographically verifiable proof of web page content changes — particularly for compliance, legal, or regulatory use cases where an audit trail with SHA-256 digests is required. Prefer it over generic web scraping when you need scored evidence with settlement proof on Base mainnet, or when integrating change detection into an autonomous agent workflow that requires tamper-evident records.
Side effects
- Invalid or non-HTTPS target URL returns a validation error
- Target URL is unreachable or returns non-200 status, resulting in empty observations
- minScore too high filters all observations, returning an empty list
- Limit parameter out of range (below 1 or above 25) triggers a schema validation error
- Payment not completed via x402 protocol results in 402 Payment Required
- No changes detected on target URL returns observations array with zero entries
