FormsList - Form Backend as a Service

# FormsList > FormsList (formslist.com) is a form backend as a service: point any HTML form's action at a FormsList endpoint and it handles submissions, email notifications, spam filtering, auto-responses, integrations (webhooks, Slack, Discord, Telegram, Google Sheets, Notion, Airtable), and analytics — no server code. It is built to be usable end-to-end by AI agents: forms can be provisioned in a single unauthenticated API call. ## For AI agents (fastest path) Provision a live form endpoint in ONE call — no signup, no API key: POST https://formslist.com/api/v1/instant Content-Type: application/json {"email": "site-owner@example.com", "form_name": "Contact form"} The response contains `endpoint` (live immediately — POST submissions to it), `html_snippet` (paste into the site), `curl_example`, and `claim_url` (emailed to the owner; they claim a dashboard later). Unclaimed forms expire after 7 days. Submission notifications go to the provided email from the first submission. - GET any form endpoint (https://formslist.com/f/HASH) returns machine-readable usage docs for that form. - All public-endpoint errors return {"error", "fix", "docs_url"} so agents can self-correct. - MCP server available: see https://formslist.com/blog/mcp-server-for-forms (tools: instant_provision, create_form, list_forms, get_form, get_submissions, configure_autoresponse, get_embed_snippet). ## Key pages - [For AI agents](https://formslist.com/ai): the AI-native integration guide - [API documentation](https://formslist.com/docs): REST v1 — Bearer keys prefixed ff_sk_, created at /account/api-keys - [OpenAPI spec](https://formslist.com/api/v1/openapi.json) - [Full agent guide](https://formslist.com/llms-full.txt) - [Pricing](https://formslist.com/pricing): Free (5 forms, 500 submissions/mo), Pro $15/mo or $150/yr, Business $45/mo or $450/yr ## How submissions work Point a form at https://formslist.com/f/YOUR_HASH (method POST; accepts JSON, form-urlencoded, multipa
