AI that reads your APIs and tells you what's wrong.
Centralizing docs is the start. Endrel's reviewer continuously checks your specs against each other and against your live endpoints, then surfaces the gaps before a customer ever hits them.
How it works
Four steps, then it keeps going on its own.
Set it up once. After that, the reviewer runs continuously so your docs stay honest without anyone babysitting them.
Connect
Point Endrel at your imported specs and, optionally, your live endpoints.
Scan
The reviewer reads every endpoint, schema, parameter, and response shape.
Surface
Drift, gaps, and inconsistencies show up as a clear, prioritized list.
Resolve
Fix in place or assign to the owning team — then it re-checks automatically.
What it catches
The mistakes that usually surface in production.
Each check targets a specific way docs and code drift apart — the kind of gap a human reviewer misses on a busy week.
// drift
Schema drift
Response shapes that quietly moved away from the published schema — new fields, changed types, dropped properties.
// gap
Coverage gaps
Endpoints documented in one place but missing in another, or live routes that never made it into the docs at all.
// inconsistent
Mixed conventions
Naming, auth, and error handling that disagree from one service to the next — the kind of friction that slows every integration.
// unclear
Missing examples
Endpoints with no example response or a description too thin to act on. The reviewer suggests clearer ones as you go.
// breaking
Breaking changes
Fields removed or types changed that downstream consumers still depend on — flagged before they reach a release.
// auth
Auth & error mismatches
Endpoints that document one auth scheme or error format but behave differently in practice.
In practice
A review reads like a clear to-do list.
No wall of warnings. The reviewer scans the service, separates what's fine from what isn't, and hands you a short, specific list — each issue tied to the exact endpoint and the exact thing that changed.
- ›Every issue points to a real endpoint and field
- ›Healthy endpoints are confirmed, not just ignored
- ›You leave with a count of what's left to review
You stay in control
AI flags. Your team decides.
The reviewer is a second set of eyes, not an autopilot. It points at what looks wrong and explains why — every change is yours to accept, reassign, or dismiss.
Nothing changes silently
The reviewer never rewrites a spec on its own. It proposes; you approve. Your docs only move when you say so.
Every flag has a reason
Each issue spells out what it found and where, so you can judge it in seconds instead of reverse-engineering a vague warning.
Owners, not blame
Issues route to the team that owns the endpoint, so the right people see the right gaps — without a status meeting.
AI review, explained
What the reviewer does—and does not do
Clear boundaries around automation, supported formats, data handling, and private APIs.
01Will the AI ever change my documentation or specification automatically?
No silent rewrites. The reviewer surfaces an issue, explains what it found, and leaves the decision with your team. A suggested change only moves forward when someone reviews and approves it.
02Can it detect breaking changes before they reach production?
It can flag changes such as removed fields, changed types, missing endpoints, and inconsistent contracts when those differences are visible in the specifications or connected review sources. It is a review aid, not a guarantee or a replacement for tests and release checks.
03What API formats does the reviewer support?
OpenAPI, Swagger, and imported Postman collections are the supported starting points. The depth of a review depends on the schema, examples, and response detail available in the source.
04Is my API data used to train AI models?
Endrel uses submitted API documentation to provide and improve the review service, and does not sell personal information. We have not published a blanket no-training commitment or final model-provider policy yet. During Founding Access, do not include secrets or production credentials, and contact us before submitting highly sensitive specifications.
05Can the reviewer safely work with private or internal APIs?
Endrel supports controlled workspaces and uses encryption in transit, but no hosted service can promise absolute security. Remove credentials and secrets from specifications before importing them. If an API is highly sensitive or regulated, speak with us about the current safeguards before connecting a live endpoint.
