01 / Usage fingerprint
Know the exact API surface you depend on.
Contractive maps the endpoints, fields, types, and parameters present in your real codebase—not a generic inventory of an entire provider API.
API change intelligence
APIs change. You stay ahead.
Contractive detects upstream contract changes, pinpoints the real usage they affect, and opens a validated remediation PR before production feels the blast radius.

One continuous loop
From upstream drift to a reviewed patch.
A provider can change fifty things. You should hear only about the ones that touch the code you ship.
Built for precision, not alert volume.
Detection stays rule-based and conservative; code generation begins only after a genuine, affected break is confirmed.

02 / Deterministic diff
Separate a real risk from another noisy changelog entry.
Curated provider contracts are checked for renamed fields, changed types, newly required parameters, and removed enum values. Only affected usage moves forward.

03 / Validated remediation
Give your team a focused PR before production absorbs the change.
A narrow patch is generated only after a confirmed break, validated against your code structure, and opened through permissions your team controls.
Trust-first by design
The agent lives where your code already lives.
Contractive is designed to run in your repository and CI. It protects the integration surface without asking you to trust a third party with sweeping repo permissions.
Your environment
Repository scan, contract checks, and patch validation execute under controls your engineering team owns.
repository → CI → affected call site → validated PR
Design partner program
Help define the reliable way to stay ahead of API drift.
We’re working with teams that depend on fast-moving APIs and want precise change detection before silent failures reach customers.
