# Drop-in APIs

> Drop-in APIs builds small, honestly-scoped tools for people and AI agents: free guards and checks that run locally, paid hosted checks only where a free local answer is not possible, and public Apify Actors. Every product page states its price and its real limitations in the first screen.

## Products

- [DoneLatch](https://alidaram99.github.io/donelatch/): DoneLatch refuses an AI coding agent's “done” until a fresh check passes, and until that check has been shown to fail when the required behavior is broken. (Free)
- [ExactGround](https://alidaram99.github.io/exactground/): ExactGround blocks an AI coding agent from installing an npm or PyPI package that does not exist, and its hosted check tells you whether a function exists in the exact version you have installed. (Free guard, paid hosted checks)
- [CanaryIndex](https://alidaram99.github.io/canaryindex/): CanaryIndex runs the same public file through document and transcription tools and publishes the quality, the cost, and the raw result, including when a tool could not be measured. (Free)
- [Waraq (ورق)](https://alidaram99.github.io/waraqmd/): Waraq is a free offline Markdown reader and editor that can be the app Windows, macOS, Linux and ChromeOS use when you open a .md file. On Android it installs and accepts shared files, though not yet as a file-manager default. (Free)

## New

- [Structured Data to JSON](https://alidaram99.github.io/api-alternatives/structured-data-to-json-api/): Turn a public product, article, event, organization, local-business or docs page into validated JSON with evidence for every field. No LLM, no invented values. $0.009 per validated page.
