# Pre-flight up to 100 numbers in one call

`POST /v1/compliance/check/batch`
Each number runs the full gate and is metered as its own verdict, so a batch of 100 costs 100 verdicts. A campaign-sized list belongs in a campaign, which has a pre-flight built for that scale.

Requires the `write` scope.

## Request body

| Field | Type | | Meaning |
|---|---|---|---|
| `e164s` | string[] | required | The numbers to pre-flight, 1-100. Each one runs the full gate and is metered as its own verdict. A campaign-sized list belongs in a campaign, which has a pre-flight built for that scale. |
| `purpose` | string | optional | The sender classification this call falls under, which decides the legal calling window and whether consent is required. Omit to use your organisation's declared `defaultCallPurpose`. It may only ever narrow — you cannot declare a stricter default and then send a looser purpose per request. Applies to every number in the batch. Open set — handle an unrecognised value rather than throwing. Today: `promotional`, `service`, `transactional`, `collections`. |
