filtoor logo is a service that provides a performant API for cNFT spam detection on Solana, created by the maintainers of cnft-spam-filter.

We currently offer a free rate-limited public API and can work with projects to offer higher rate limits. Get in touch with us to discuss.

Feel free to read our documentation and play with our API in our playground.

We are open source and rely on community support to keep going. If you would like to contribute, please send any SOL assets to:




We very much appreciate your support in fighting spam on Solana ❤️
