Collateral Score Batch (submit)

Existing customers on legacy plans: Score up to 500 vehicles asynchronously, e.g. to re-score a loan book. Returns 202 with a batch_id; poll GET with it, or pass webhook_url to receive collateral_score.batch.completed. The example VIN 3TMKB5FNXRM012539 is free and never counted. Usage is checked up front for every other vehicle, so a 429 means the remaining quota is smaller than that count. Plans that allow overage are billed one Collateral Score call per vehicle that scores, when the batch completes. Hard-capped and prepaid plans are charged for every vehicle except the example VIN at submit, before the 202. One batch runs per account at a time.
