- URL: `https://api.counselorai.app/v1/tools/letterlens/quote`

Free pre-flight. Validates the input and returns the exact credit hold a real call would take at this account's price, without billing anything. An invalid input is still a 200: the body carries valid:false and the validation errors.

  - `purpose` 'rec_college' | 'rec_scholarship' | 'rec_transfer' | 'rec_professional' | 'rec_employment' | 'rec_program' | 'undergraduate' | 'graduate' | 'scholarship' | 'transfer' | 'internship' | 'other': What the letter is for. A scholarship letter is read differently from a transfer letter.
