Commerce API & MCP › Usage
Commerce API Usage
Project request counts, REST API keys, Commerce MCP credentials, and quota details live in Developer Console. Sign in to review each project.
Signup credit
Registration attempts the one-time signup grant once for every new developer account.
If the grant is absent, contact support for manual remediation. It is not retried or backfilled automatically. No credit card is required, and you can purchase additional credits whenever you need them.
Operation costs
Each of the four Commerce operations costs a fixed number of Commerce Credits per call.
| Operation | REST | Commerce Credits |
|---|---|---|
| Resolve product | POST /api/v1/commerce/resolve-product | 3 |
| Search products | POST /api/v1/commerce/search-products | 5 |
| Find offers | POST /api/v1/commerce/find-offers | 5 |
| Deep search | POST /api/v1/commerce/deep-search | 10 |
Billing behavior
- Successful, billable responses consume Commerce Credits.
- Non-billable failures do not consume any credits.
- Replaying the same idempotent request is never billed twice.
- Your remaining balance is always visible in the Developer Console.
- Additional Commerce Credits can be purchased at any time.
