# Deliverability Score per verified domain, and the worst

`GET /v1/deliverability`

- Authentication: required (Bearer token)
- Required scope: `api.reports.view`

One row per adopted, verified sending domain from its latest nightly
snapshot (05:40 UTC), plus `org_summary`: the org as its **worst**
assessed domain — worst band, then lowest score — never a mean.

A score is the weighted share of DECIDED checks that pass. `unknown`
checks are **excluded from the denominator** and reported in
`coverage`; they never count as zero or as a pass. Bands: `healthy`
≥ 90, `at_risk` 70–89, `failing` < 70 — **except that any `blocking`
task forces `failing`**, whatever the number. A domain with no snapshot
yet is `not_yet_assessed`, with null `score`, `coverage` and
`taken_at` — never zeros.

Cursor-paginated over the domains; `org_summary` always covers every
domain, not just the page. Available on every plan. Read-only.

## Query parameters

- `limit` (integer, optional) — Page size (1–200). Default 50.
- `cursor` (string, optional) — Opaque cursor returned from the previous page.

## Example request

```bash
curl 'https://api.sendops.dev/v1/deliverability' \
  -H "Authorization: Bearer $SENDOPS_API_KEY"
```

### 422 — A query parameter, path value or body field failed validation.

The body is a `validation_failed` Problem. When the refusal is about a
reference — a segment key, template slug, topic or attribute name the
organization does not have — it additionally carries `validation_code`,
`field`, `line`/`column`, `missing`, `candidates` and `next_step`, so a
client can correct the call without a second round of guessing. See
`ValidationProblem`.
