Email OTP in two calls: send and verify.

// Send: we make the code, hash it and email it.
const { otp_id } = await signops.otp.send({
  email: "ananya@example.in",
  app_name: "Kirana Express",
});

// Check: true once, then the code is gone.
const { valid } = await signops.otp.verify({
  otp_id,
  code: req.body.code,
});

$otp = $signops->otp->send([
    'email'    => 'ananya@example.in',
    'app_name' => 'Kirana Express',
]);

$result = $signops->otp->verify(
    $otp['otp_id'],
    $request->input('code'),
);
$ok = $result['valid'];

otp = signops.otp.send(
    email="ananya@example.in",
    app_name="Kirana Express",
)

result = signops.otp.verify(
    otp_id=otp.otp_id,
    code=request.form["code"],
)
valid = result.valid
