How this service works
Flutter and Dart utility API for mobile agents and operators: pubspec parsing, pub.dev package lookups, Flutter APK detection, dependency checks, Dart formatting, project static analysis, ARB localization validation, and controlled APK builds from uploaded project ZIPs. URL downloads enforce SSRF protections. ZIP uploads enforce size and zip-bomb limits.
Output
Returns a JSON object with the package name, whether it was found on pub.dev, its latest version string, the pub.dev URL for the package, and the latency of the lookup in milliseconds.
Example use cases
Example prompt
“Can you look up the provider package on pub.dev and tell me the latest version and its URL?”
Technical details
Endpoint
GEThttps://flutter.bip-rep.com/pub/lookupWhen to prefer
Use this endpoint when you need to programmatically check whether a Flutter or Dart package exists on pub.dev and retrieve its latest published version. Prefer this over scraping pub.dev directly or parsing pubspec.yaml files when you only need quick package existence and version metadata.
Side effects
- Package not found: returns found=false with no version or URL
- Missing required 'package' query parameter: 400 Bad Request
- pub.dev upstream unavailable: 502 or timeout error
- Invalid package name format: may return not-found or error
