How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with package metadata from pub.dev, including package name, latest version, description, publisher, homepage, and potentially dependency and score information.

Example use cases

Check latest Flutter package version

“What's the latest version of the 'dio' package on pub.dev, and who maintains it?”

Inspect Dart library metadata

“Pull up the pub.dev details for 'freezed' — I want to know its description, current version, and whether it's still actively maintained.”

Research package before adding dependency

“Before I add 'get_it' to my Flutter project, can you grab its pub.dev info so I can see what it does and how popular it is?”
