API Reference
Hexcovery exposes a small, deliberate programmatic surface. Everything an automation or integration needs is reachable with a tenant-scoped API key over HTTPS — there is no raw-SQL endpoint, no page-scraping API, and no way to reach ClickHouse directly. You query with OQL, mark events with annotations, and report scheduled-job runs with heartbeats. Bulk telemetry (traces, logs, metrics) arrives over OTLP on gRPC — see Sending Data.
The programmatic surface
These are the only HTTP endpoints an API key can touch. Authenticate every request with the X-API-Key header.
| Endpoint | Method | Purpose | Reference |
|---|---|---|---|
/api/v1/dsl |
POST |
Execute an OQL query and get back columns + rows | Query API |
/api/v1/annotations |
GET |
List annotations (filter by time range, name prefix) | Annotations API |
/api/v1/annotations |
POST |
Create an annotation (e.g. a CI/CD deploy marker) | Annotations API |
/api/v1/annotations/:id |
PUT |
Update an annotation | Annotations API |
/api/v1/annotations/:id |
DELETE |
Delete an annotation | Annotations API |
/api/v1/heartbeat/* |
POST |
Report a cron-job run (start / log / end / ping) | Heartbeat API |
Plus OTLP ingest on :4317 (gRPC) for traces, logs, and metrics — covered under Sending Data, not here.
That is the complete list. Anything else under /api/v1/* (overview, hosts, logs, traces, schema, dashboards, …) backs the dashboard UI and requires an authenticated user session (a JWT), not an API key.
Authentication in one line
curl -X POST https://server/api/v1/dsl \
-H "X-API-Key: $HEXCOVERY_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query":"SELECT avg(cpu_user_pct) FROM host LAST 1h"}'
The X-API-Key header is the only credential automation uses. The Authorization: Bearer slot is reserved for dashboard JWTs and will not accept an API key. See Authentication for the full model, and API keys for creating and rotating keys.

- Authentication — API keys vs JWTs, and which slot each one uses.
- Query API —
POST /api/v1/dsl: run OQL, read the JSON result. - Annotations API — create and manage event markers from CI/CD.
- Heartbeat API — report scheduled-job runs.
