About Poly
Poly is an integration reliability platform that protects your application from third-party API breaking changes — without ever proxying your traffic.
When external APIs change their response schemas (renamed fields, removed fields, type changes), your code breaks. Poly detects these changes in real-time, generates safe AI-powered mappings, and patches responses locally before your code sees them.
Unlike API gateways or proxies, Poly never sees your data. Only schema metadata (field names and types) is sent to the cloud for analysis. Your payloads, user data, and business logic stay on your machine.
How It Works
- Install the Poly SDK and wrap your HTTP client (Axios or Fetch)
- Poly learns your API schemas by observing responses
- When drift is detected, schema metadata is sent to Poly Cloud
- AI analyzes the change and generates safe field mappings
- Patches are applied in-memory — your code never notices the change
