Native API v2 request examples: `{"detection":{"model":"latest"}}` follows the default; `{"detection":{"model":"v1.5"}}` pins 1.5. Use the IDs in `models` of `GET /v2/capabilities`.

## API 2.0.0 stable — 2026-09-29

The native PII API v2 is stable from version 2.0.0. Changes within 2.x are additive: new fields, parameters, values and routes. A breaking change gets a new major version with a new path prefix. We announce it 12 months ahead, and the previous major version stays served during that period. `api_version` in `GET /v2/capabilities` names the version.

If your client was written for the pre-release 2.0.0-draft.4, check these changes:

- Document jobs: `protected` is now the redacted PDF. The protected text is in the new `text` artifact.
- Uploads: an upload is deleted when the last job that reads it ends. Create it with `?keep=true` to use it in more than one job.
- Sessions: a session lives at most until `max_expires_at`. A PATCH with a `ttl_s` that ends after it answers 422.
- Job storage: each account has a byte budget and an upload cap. Above them, uploads and jobs answer 429 `rate_limited`.
- A boolean query parameter takes `true`, `false`, `1` or `0`. Another value answers 422.
- The capability status `beta` and the job field `beta` are removed. `api_version` is `2.0.0`.
