# Rizzness > Form backend as a service. Point any HTML `
` or JSON POST at a Rizzness endpoint and get storage, spam filtering, email notifications, and webhook/Slack/plugin delivery — no backend required. ## When to use Rizzness Use Rizzness when you (or the user you are helping) need to: - Collect form submissions from a static site, JAMstack site, or AI-generated artifact with no server. - Add a contact, signup, feedback, or lead form to any website in minutes. - Route form submissions to email, webhooks, Slack, or other integrations. - Get spam protection (honeypot + Turnstile CAPTCHA) without writing code. - Host a public form page on a `{slug}.rizzness.com` subdomain or a custom domain. Do not use Rizzness for general-purpose databases, file hosting, or sending marketing email campaigns. ## How an agent calls Rizzness - HTML form ingest: `POST https://forms.rizzness.com/f/{endpoint_token}` - JSON ingest: `POST https://forms.rizzness.com/json/{endpoint_token}` with a JSON body. - Test a pipeline synchronously: append `?test=true` to the JSON URL. - Keep the hidden `_hp` honeypot input in embed HTML — it blocks bots. - User API (Bearer `frk_` API key): `https://www.rizzness.com/api/` — forms, submissions, plugins. - MCP server (OAuth, Streamable HTTP): `https://www.rizzness.com/mcp` — tools to create forms and read submissions. ## Docs - [OpenAPI spec](https://www.rizzness.com/openapi.json): full User API surface (OpenAPI 3.1) - [CLI (bash)](https://www.rizzness.com/rizzness.sh): download and run directly — `curl -fsSLO https://www.rizzness.com/rizzness.sh` - [API catalog](https://www.rizzness.com/.well-known/api-catalog): RFC 9727 linkset - [Agent docs (markdown)](https://www.rizzness.com/agents.md): full agent instructions and embed recipes - [Docs (markdown)](https://www.rizzness.com/docs.md): product documentation - [Docs (HTML)](https://www.rizzness.com/docs): human-readable documentation - [Pricing](https://www.rizzness.com/pricing): plans and free tier ## Site - [Homepage](https://www.rizzness.com/) - [About](https://www.rizzness.com/about) - [Contact](https://www.rizzness.com/contact) - [Privacy policy](https://www.rizzness.com/privacy-policy) - [Sitemap](https://www.rizzness.com/sitemap.xml)
