Quick start

Call Bulk Email Checker from your generated app's worker code via the OverSkill composio client. The toolkit slug below maps to Bulk Email Checker's public Composio identifier — your app references it by name and OverSkill handles the OAuth round-trip.

// In your generated app's worker handler:
const composio = composioClient(env);

const result = await composio.execute(
  "BULK_EMAIL_CHECKER_ACTION_NAME",
  { /* action parameters — see Actions section below */ }
);

return new Response(JSON.stringify(result), {
  headers: { "Content-Type": "application/json" }
});

Replace ACTION_NAME with one of the slugs listed in the Actions section below. The composio client handles auth + rate limits automatically — no API key is exposed to user code.

Setup

Bulk Email Checker is newly synced from Composio — our background bootstrap job hasn't created the auth config row yet. This usually takes a few minutes; if it's still pending after an hour, please reach out.
