Self-maintaining API integrations

APIs shift.
Code follows.

Tektonik watches every third-party API you depend on. When an API changes, it finds the code the change affects, writes the fix, tests it, and opens a draft pull request for your team to review.

    A new era of integrations.
    Your codebase, self-maintaining.

    Every API you call can change: endpoints are removed, fields change type, new auth is required. Today someone learns about it from a production error. With Tektonik, the fix arrives as a pull request before anything breaks.

    The API

    “items[].id is now returned as a string. Integer IDs will be removed on Nov 15.”

    How it works

    API migrations,
    done automatically.

    01

    Detected.

    Tektonik polls official specs, changelogs and deprecation notices, diffs each new version against the last, and records every change with a link to its source.

    ChangeCard · confidence 0.95
    02

    Mapped.

    Each change is matched against an index of your code to find the exact endpoints, files and functions it affects, then rated high, low or unknown impact.

    Fixed.

    Claude writes the smallest safe fix on an isolated branch. Tektonik runs your tests, linter and type checks, then opens a draft pull request with the evidence and a rollback plan.

    Seven agents.
    One auditable pipeline.

    Each stage hands off a schema-validated record, so every decision is stored with the evidence behind it. If a check fails, Tektonik retries a limited number of times and then hands the change to a person.

    1. changeWatcher Watch

      Polls specs and feeds, snapshots each version.

    2. normalizer Normalize

      Diffs specs field by field and deduplicates announcements.

    3. impact Assess

      Matches each change to your code and rates its severity.

    5. fix Fix

      Claude edits only the files that need it, on an isolated branch.

    6. test Test

      Runs lint, types, unit and contract tests against mocks.

      A person reviews it and decides whether to merge.

    Why Tektonik

    What makes Tektonik different from a dependency bot?

    Dependency bots bump version numbers. Tektonik reads what changed in the API, finds the code that uses it, and makes the edit.

    Start a pilot
    1. 01

      Reads the API, not just the version number.

      It diffs endpoints, parameters, request and response schemas, and auth. Plain-language changelogs are parsed too, and anything inferred from them is labeled as inferred.

    2. 02

      Knows exactly where you call each endpoint.

      A usage index links each method and path to the files and functions that call it, and updates with every push.

      "stripe/payments": {
  "GET /v1/invoices": {
    files: ["src/billing/client.py"],
    symbols: ["fetch_invoices"]
  }
}
    3. 03

      Triages by impact.

      Breaking changes go to migration planning. Compatible improvements are adopted only if they clearly pay off. When the evidence is unclear, Tektonik asks a person instead of assuming it's safe.

    4. 04

      Every claim links to its source.

      Each change is tied to an official URL or a location in the spec. Tektonik never invents API behavior, benchmarks or passing tests.

    5. 05

      Tested before you see it.

      Lint, type checks, unit, contract and security tests all run against mocks or vendor sandboxes. A failed or missing critical check keeps the PR in draft.

    6. 06

      People merge. Always.

      Tektonik never merges or deploys on its own. Changes that touch credentials, billing or authorization, or that could lose data, need explicit sign-off.
