Dependabot for third-party APIs
When vendor APIs break,
open a fix PR — not an incident.
Apimend watches provider OpenAPI specs and changelogs. When something breaks, it finds the call sites in your codebase and opens a verified PR that already passes tests.
No spam. Built for API providers and eng teams.
Starting with
The problem
Changelogs don’t page you. Production does.
Before
Changelog email → ignored → prod 500s → war room → manual grep → rushed PR → hope CI passes
After Apimend
Spec diff → call-site map → verified PR in review queue → you merge when ready
How it works
Three steps. No silent breakage.
01
Detect
Track provider OpenAPI + changelogs. Emit a machine-readable breaking-change delta. Stripe first — pinned SDKs make this reliable.
oasdiff · OpenAPI · changelogs
02
Map + fix
Scan the repo. Deterministic codemods handle the mechanical 80%. An agent handles the semantic 20% — renames, shape shifts, auth tweaks.
codemod · AST · agent
03
Gate
Typecheck + tests must pass before anything opens. Verification-before-PR is the product. You review. You merge.
tsc · tests · never auto-merge
Product
A PR factory, not another dashboard.
Install the GitHub App. Point it at the vendors you depend on. When a break lands, Apimend opens a reviewable PR with a clear diff and passing checks.
-
Always on Watches specs continuously — not a one-shot agent chat
-
Deterministic first Codemods before LLMs. Lower false positives.
-
Human in the loop Nothing merges itself. Your CI is the gate.

FAQ
Straight answers
Does it auto-merge?
No. Apimend only opens PRs after checks pass. Your team reviews and merges.
What does it need access to?
A GitHub App with read on contents and write on pull requests. It does not need deploy keys or production secrets.
Why Stripe first?
Pinned SDKs + public OpenAPI make breaks machine-readable. That is the highest-confidence wedge before wider providers.
Who is this for right now?
Design partners: API provider DevX teams, and eng teams deep on Stripe + TypeScript.
Is this just “wrap Claude in a bot”?
No. Detection is deterministic (spec diff). Most fixes are codemods. The agent only handles the semantic remainder, and nothing opens without CI green.
