# GET /api/v1/diagnostics

> Symptom-driven triage for one target

- Group: diagnostics
- Tier: R
- Required scope: read:hosting
- Docs: https://api.inleed.com/reference/diagnostics/diagnose

## Description

Give a `symptom` (`slow|down|email|ssl|dns|disk|billing`) and the resolved target; returns `{target, symptom, verdict, summary, findings:[{severity, title, evidence, recommendation}], notes[]}`. `verdict` is the most severe finding (`critical|warning|info|ok`), each finding carrying a plain-language `recommendation`. It composes the existing domain reads; it writes nothing.

## Query parameters

- `input` — string (required). A domain, email address, website URL, or Inleed service id — for example example.se, info@example.se or 42976. Resolved to the owning account automatically, and the resolved target is echoed back in the response.
- `symptom` — enum (required). What the customer reports: slow, down, email failing, ssl certificate issue, dns misconfiguration, disk full, or billing problem. One of slow, down, email, ssl, dns, disk, billing.

## Request

```bash
curl -X GET "https://mcp.inleed.com/api/v1/diagnostics?input=example.se&symptom=slow" \
  -H "Authorization: Bearer inl_live_…"
