Gates

Require proof before an action happens. You decide what must already be proven, the person verifies, and you keep the result. A single check needs no gate. For one proof-of-human requirement, send the person to Hosted Verify and read the returned proof ID. Verify covers that path. Use a gate when the decision needs several checks, a price, or a schedule. Publish it as a listing when you want a persisted gateId, price, schedule, or marketplace offer.

What a gate holds

Part	What it sets
Checks	What must already be proven, with optional match rows such as a provider or minimum age
Price	Optional. Free unless you publish a charge
Schedule	Optional start and end times, enforced on the server when published
Reward	Optional. What people receive after they pass a published listing

Enforce it

Where	How
Your server	`defineGate` + `gateCheck`. `satisfied === true` means ready
A React page	`VerifyGate` with the `gate` policy
A published listing	`VerifyGate` with a `gateId`, or a hosted checkout link
An API	Pay per call with a proof check
An agent action	The agent’s permission check before the tool runs. Control agent actions

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

const proofable = new ProofableClient();
const gate = defineGate([
  { verifierId: 'proof-of-human' },
  { verifierId: 'ownership-dns-txt', match: [{ path: 'domain', value: 'acme.com' }] },
]);
const result = await proofable.gateCheck({ gate, subject });
if (result.satisfied) {
  // grant access
}

import { defineGate } from '@proofable/sdk';
import { VerifyGate } from '@proofable/sdk/widgets';

const gate = defineGate([
  { verifierId: 'proof-of-human' },
  { verifierId: 'ownership-dns-txt', match: [{ path: 'domain', value: 'acme.com' }] },
]);

<VerifyGate gate={gate} onVerified={grantAccess} />;

How a check runs

Define the policy. Verifier IDs plus optional match, freshness, and count rows.
Check existing proofs. gateCheck evaluates the subject’s current proofs against that policy.
Verify what’s missing. Hosted Verify or your own verify call covers only the gaps.
Decide. satisfied is the decision, and your server grants the access, so the final call stays yours.

Who pays

Checks on a published listing use your credits by default. Turn on visitor checkout to charge a price instead. Inline defineGate checks and other API calls can be sponsored by your app or paid per call with x402. Pricing
