Cap the clearing cheque. Keep the provider key.

Isolate the clearing-cheque traffic, not the provider account.

1. 01
   Issue a disposable Till key for the clearing-cheque job

   Set the request ceiling from expected MICR, serial, clearing-house, and settlement-date fields and retries, then add optional token, estimated-spend, expiry, and IP bounds when the clearing worker needs a tighter envelope.

2. 02
   The provider credential stays behind Till

   The clearing-cheque job uses a Till key, not an unconstrained provider secret in the worker process. When the job is retired, revoke or let expiry stop that key without rotating every connection.

3. 03
   This is not a bank or clearing house

   Till does not clear cheques, settle them through a clearing house, or replace a paying bank. It is a hosted control layer in front of 12 AI providers: a required request ceiling and optional token, spend, expiry, and IP controls.

4. 04
   Pro: $59/month, 25 scoped keys, 25,000 monthly activations

   Those are plan limits. Public signup is closed; request Pro beta access. Provider inference is billed by the provider. Till charges a platform subscription.
