# Generate
Canonical URL: https://mbretrofit.it/guides/api/seed/generate


Generates through the same engine, funding rules and history used by the workspace.
Send `definitionId` from `/seed/definitions` and `seedValue` as compact or
space-separated hexadecimal bytes. The existing `originId` and `level` fields
are accepted when they identify exactly one definition. Ambiguous selections
return HTTP 409 and require an exact `definitionId`.

Call `POST /seed/quote` with the same body to validate the seed and see your
account's `creditCost`, `balance`, `unlimited` and `canAfford` values without
charging or generating. Generation checks pricing and balance again in its
transaction; a quote does not reserve credits.

Aston Martin EZS213 Rel\_21 defaults to 5 seed credits. Regular EZS213 defaults
to 1. Zero-cost definitions and account-specific zero-cost overrides work with
an empty balance. A Professional subscription does not automatically waive
seed-key charges.

Successful generation returns `seedKey` and `created`. Retrieve the saved result
using `GET /seed/get?id=<created>`. Each new generation request is charged
separately; use the saved ID to retrieve an existing result.
