Example prompt: I need to buy the MV3 Declared Access Diff tool from Speedbot to audit permission changes in my Chrome extension between releases — use my email dev@example.com, generate a fresh checkout key and request ID, and confirm I consent to immediate digital delivery.

## When to prefer this

Choose this endpoint when you need a self-contained, offline Python tool to audit Chrome extension MV3 manifest permission changes between releases without runtime dependencies. Prefer it over manual manifest inspection when you need a repeatable, scriptable diff of host patterns, required permissions, and optional API access across extension versions, especially in a CI/CD or code-review workflow.

## Known failure modes

- Missing or invalid email format causes rejection of purchase request
- checkout_key not exactly 64 hex characters returns validation error
- request_id shorter than 16 characters or longer than 100 characters is rejected
- digital_delivery_consent not set to true blocks purchase completion
- Duplicate request_id on a new purchase (not a retry) may cause conflicts
- Payment of 1 USDC not available or wallet insufficient funds causes transaction failure
- First-time purchase at 0.01 USDC discount only applies if maker terms permit; subsequent calls billed at full 1 USDC
