The Vext Labs docs landing covers everything you need to add verifiable AI-action receipts to your app, and to check anyone else's. Install with npm i @vextlabs/stoa, then verify with npx @vextlabs/stoa-verifier. Six sections organize the material: Quickstart, The verifier, Receipt format, SDK reference, Concepts, and the Changelog.
Quickstart takes you from zero to your first signed receipt in about five minutes. The verifier runs in the browser or the CLI: it is Apache-2.0, has zero dependencies, and works fully offline, so you check a receipt without trusting the vendor that issued it. The Receipt format section walks the envelope, the ES256 signature, and the daily Merkle anchoring field by field. The SDK reference documents issueReceipt(), the eval track, and wrapping your existing agent calls. Concepts explains receipts, anchoring, and what verify without trusting the vendor actually means.
The Changelog records what shipped and when, and every entry links to the receipts that prove it. This is the proof layer Theron is built on: receipts are ES256-signed, anchored to a daily Merkle root, and checkable with the open-source offline verifier, no account required. You can also subscribe to the dispatch to get new guides and changelog entries by email as they ship, receipts attached.
Run npx @vextlabs/stoa-verifier from the CLI, or use the verifier in the browser. It is Apache-2.0, has zero dependencies, and works fully offline, so you can check any receipt without trusting the vendor that issued it. No account is needed.
The Receipt format section documents the envelope, the ES256 signature, and the daily Merkle anchoring, field by field. Receipts are ES256-signed and anchored to a daily Merkle root so they can be checked independently.
Quickstart takes you from zero to your first signed receipt in about five minutes. Install with npm i @vextlabs/stoa, then follow the Quickstart and SDK reference, which cover issueReceipt() and wrapping your existing agent calls.
Yes. The Changelog records what shipped and when, and every entry links to the receipts that prove it, so each claim is backed by a verifiable receipt rather than a release note alone.
