How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 on Base.
Output
Returns a signed attestation record containing a timestamp, the captured page text, and (if enabled) a cryptographic hash of a screenshot — usable as verifiable, point-in-time evidence of the page's content for disputes, compliance, or archival.
Example use cases
Locking in a competitor's price claim
“Attest to this product page at https://competitor.com/product/widget-pro with a screenshot — I need a timestamped, tamper-evident record of the price they're advertising right now in case they change it.”
Preserving a terms-of-service snapshot
“Can you create an attestation of https://saas-vendor.com/legal/terms with a screenshot included? I need verifiable proof of what their ToS says today before we sign the contract.”
Recording a published policy for compliance
“Capture and attest to https://supplier.com/shipping-policy — I need the text and a hashed screenshot so we have evidence of their stated policy if a dispute comes up later.”
Technical details
Endpoint
POSThttps://extract.tollkit.dev/attest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically verifiable, timestamped proof of what a specific web page contained at a given moment — especially for dispute resolution, legal evidence, compliance archiving, or preserving competitor claims and pricing. Prefer it over simple screenshots or scraping when the integrity and non-repudiation of the record matters. Its x402 pay-per-call model means no account setup is needed, making it ideal for ad-hoc, automated, or agent-driven evidence capture.
Side effects
- Non-https or invalid URL returns a validation error
- Page behind authentication or bot-blocking may return incomplete or empty content
- Screenshot capture failure may return a weaker text-only attestation
- Payment failure via x402 results in no attestation being created
- Timeout on slow-loading pages may yield partial content
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| url | string | Absolute https:// URL of the page to attest to. Anything a dispute could turn on: terms of service, a price, a published policy, a competitor's claim, a listing that may be edited later. |
| screenshot | boolean | Capture and hash a screenshot. On by default — an attestation without one is much weaker evidence. Turn it off for a faster, text-only record. |
