• errorMessage (string) – in case of error; otherwise null

• proof (string): proof-of-humanity (a hex string); null in case of error

Usage with poh-react

import hCaptchaValidator from 'poh-validator-hcaptcha';
import { useProofOfHumanity } from 'poh-react';

const validator = (
  <HCaptchaValidator
    validatorApiUrl="http://localhost:3000/api/v1/proof"
    sitekey="10000000-ffff-ffff-ffff-000000000001"
  />
);

const { getProofOfHumanity } = useProofOfHumanity(validator);
