MoltSets uses API key authentication. Every request must include your API key as a Bearer token in the Authorization header. 
Authorization: Bearer YOUR_API_KEY
API keys follow the format ms_XXXXXXXXXXX.

​
Creating an API key

API keys are managed at app.moltsets.com.
  1. To create an API Key, choose “create an API key”
  2. Give it a name then click “create now”
Store your API key somewhere secure as soon as you create it!

​
Using your API key

Pass the key as a Bearer token on every request: 
curl -X POST https://api.moltsets.com/api/v1/tools/get_account \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

​
Multiple keys

You can create as many API keys as you need. The recommended pattern is one key per environment or agent — for example, separate keys for local development, staging, and production. This makes it easy to revoke access for a specific environment without affecting others.

​
Revoking a key

You can revoke credentials individually or all at once:
  1. To revoke a single API Key or Connector, click Revoke to the right of the credential you want to remove.
  2. To revoke all credentials at once, use the Revoke All option on the page.
Revocation is immediate and irreversible.

​
Key permissions

All API keys have the same permissions — there are no read-only or scoped keys. Any key can call any tool on your account.
