An early-warning system for the third-party APIs your AI agents depend on, with the fix as a pull request. · tiltmeter.dev

Tiltmeter learns the shape of the APIs your code calls, notices when a provider renames a field, starts sending null or removes an endpoint, and hands the change to an agent that adapts your code and opens the pull request. In provider mode, API providers publish signed change notices and every affected repository gets its fix.

Each fork carries a fix that Tiltmeter generated for a public project after its API provider changed something, and its pull request is open in the original repository. The first was Stripe's own subscription sample, which no longer type-checks against Stripe's SDK since API version 2025-03-31. All the pull requests are public. We delete a fork once its pull request is merged or closed.
