Put the same check in your product

Define requirements in your product and enforce the result on your server. Proofable reuses existing proof before asking the user to verify again.

import { ProofableClient, defineGate } from '@proofable/sdk';

const client = new ProofableClient();
const gate = defineGate([{ verifierId: 'proof-of-human' }]);
const result = await client.gateCheck({
  gate,
  subject: { accountId: user.accountAddress },
});

if (!result.satisfied) throw new Error('Verification required');
await submitReview();

No dashboard or published listing is required. Your application owns the final allow or deny decision.

Missing verification
SDK
API

Use Hosted Verify only when the server check reports a missing verifier.

import { getHostedCheckoutUrl } from '@proofable/sdk';

window.location.assign(
  getHostedCheckoutUrl({
    verifiers: ['proof-of-human'],
    returnUrl: 'https://app.example.com/callback',
  }),
);

Re-run the server check after the user returns. Pass mode: 'popup' and origin to keep people on your page. Hosted verification

HTTP API and OpenAPI

What your users get

Your product needs	Proofable provides
Sign-in	Hosted passkey, wallet, and Google or Microsoft sign-in
Verified users	Checks that save reusable proofs
Agents for your users	An owner, identity, and permission proof for each agent
Access control	Verification UX in the browser; final decisions on your server
Payments	Visitor checkout and pay per call

Users keep their proofs. When they reach another product that accepts them, they don’t start over.

Who pays

Your app can sponsor usage, users can pay through a Listing, and agents or APIs can use x402. Payer-resolution details are in Pricing.

Keep credentials on the server

Access keys and other secrets never belong in browser code. Call Proofable from your backend when you need more than the SDK exposes in the browser.

Server integrations

Create proofs from your backend.

Hosted verification

Every parameter for the hosted flow.

Agents in the SDK

Create agents for your users with owner approval.

HTTP API

Endpoints, paging, and raw requests.
