How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
A JSON object with ok: true, an items array containing the created watcher record, total count, and a source object describing the upstream provider URL, license, and provider name.
Example use cases
Example prompt
“Set up a watcher on npm for the 'react' package — send a POST to https://myapp.example.com/hooks/releases with my payload {"project":"frontend"} whenever a new version drops, stop after 5 releases, and keep the watcher active for 30 days.”
Technical details
Endpoint
POSThttps://2s.io/api/watchers/package-releaseWhen to prefer
Use this endpoint when you need event-driven notifications for new package releases on npm or PyPI without polling — especially when building CI/CD pipelines, dependency update bots, or security monitoring systems that need to react immediately when a library version changes. Prefer this over manual polling or GitHub Action triggers when the package source is PyPI or npm specifically.
