How this service works
Use when an agent needs browser. Returns Run one headless browser action and return a verified evidence record. $0.02.
Output
Returns an AEP-compatible verified evidence object containing the result of the browser action (e.g. extracted text, DOM snapshot, or page state) along with a cryptographic attestation proving the browser observed that content at the time of the call. The evidence package is structured for use in agent pipelines, smart contracts, or compliance workflows that require tamper-evident proof of web observations.
Example use cases
On-chain price claim verification
“Navigate to the Uniswap app and capture the current USDC/ETH pool price with AEP-compatible verified browser evidence so I can submit it as a verifiable attestation to a smart contract.”
Compliance screenshot with attestation
“Load the OFAC sanctions list page and capture verified browser evidence that a specific wallet address does NOT appear in the results — I need the AEP-compatible proof for a compliance audit.”
Verified sports result for prediction market
“Go to ESPN and grab the final score of the Lakers vs Celtics game from last night, and return AEP-compatible verified evidence of what the page showed so I can resolve a prediction market.”
Technical details
Endpoint
POSThttps://api.oblique.markets/api/v1/paid/evidence/browserWhen to prefer
Choose this endpoint when you need not just the raw content of a web page but cryptographically verifiable proof that a browser observed specific content — particularly for on-chain claims, prediction market resolution, agent-to-agent trust, or compliance workflows requiring AEP-compatible attestation. Prefer this over generic web scraping endpoints when the downstream consumer needs to verify the evidence independently rather than trust the caller.
Side effects
- Target URL is inaccessible or returns an error — evidence cannot be generated
- Browser action specification is malformed or unsupported — 400-level error returned
- Page content is dynamic/JavaScript-rendered and action times out before completion
- Target site blocks headless browsers or returns a bot-detection challenge
- x402 payment not satisfied — endpoint returns 402 before executing action
- AEP attestation generation fails due to internal signing error
