Attest Capture vs generic screenshot APIs.
Choose a renderer for the artifact alone, or add a scoped public receipt, timestamp and digest when an agent needs evidence it can hand to a reviewer.
The practical difference
Capture plus a verifiable receipt.
Attest returns a private artifact, a 24-hour signed retrieval link, a UTC capture time, a SHA-256 digest and an optional public evidence page. It also includes an MCP server package in this repository for agent clients. Generic screenshot APIs are a broad provider class: their formats, metadata, storage, integrations and evidence features vary, so this page does not assign claims to any named competitor.
Capability shape
Compare the delivered record.
| Question | Attest Capture | Generic screenshot API class |
|---|---|---|
| What can the request return? | PNG, PDF or rendered HTML. | Usually a rendered artifact; supported formats vary by provider. |
| Is there a public evidence receipt? | Optional public page with source URL, timestamp, digest and scoped claim. | Receipt or public verification features vary by provider. |
| How are artifact bytes identified? | SHA-256 digest returned with every successful capture. | Integrity metadata varies by provider and integration. |
| How do agents call it? | HTTP API, plus a repository-included MCP server package that is not yet published to npm. | HTTP is common; agent-protocol adapters vary by provider. |
| How is usage purchased? | 100 free credits, then one-time credit packs. PNG and HTML cost 1 credit; PDF costs 2. | Pricing models and metering units vary by provider. |
| What does the record prove? | What the Attest renderer saw at the recorded time, bound to the stored bytes by a digest. | The claim depends on the provider's own response and documentation. |

}Honest scope
Evidence receipt, not forensic custody.
Attest Capture proves what its renderer saw at the recorded time and binds the stored artifact bytes to the displayed SHA-256 digest. It does not prove authorship, truth, legal validity or a forensic chain of custody.
