Certificates as an input to your product.

Everything this site shows, as JSON, read from the contract. Writes go to the contract itself, signed by your own wallet.

Read

method	path	returns
GET	/api/v1/certificates	The newest certificates, newest first.
GET	/api/v1/certificates/:id	One certificate, as the chain holds it.
GET	/api/v1/certificates?url=	The newest captures of one url, newest first.
GET	/api/v1/certificates?digest=	The first certificate carrying a claims digest, or a 404.
GET	/api/v1/watches/:id	A watch, with its page's history and the change between captures.
GET	/api/v1/assessments?from=&to=	The judgment of the change between two captures, or a 404.
GET	/api/contract-source	The contract's source, byte for byte, as text.

Responses are cached for five seconds. Every field name mirrors the contract's own views, so the same record can be read off the chain with no part of this site.

Write

Call the contract with any GenLayer client. Each payable call takes exactly the price its stats() view reports at that moment, and refuses anything else with a sentence saying so.

method	price	does
notarize(url)	4 wei GEN	Certify what a page states now.
notarize_contracts(targets, method_sets)	1 wei GEN each	Record other contracts' zero-argument views, up to ten per call.
watch(url, cadence_hours)	4 wei GEN per capture	Prepay captures of a page on a cadence.
capture_watch(watch_id)	free	Take a watch's due capture. Any account may.
assess(cert_a, cert_b)	2 wei GEN	Put one question about two captures of a page.

Judgments, not just diffs

A diff between two captures reports the same thing whether a fee moved from one percent to five or a sentence was reworded. The judgment separates them, answered material, immaterial or unclear, and the verify page sets out how each is reached. A 404 from the assessments endpoint means nobody has put that question yet, which is a different fact from any verdict.
