# A survey tool your AI agent can actually use

Most form builders were designed for a person clicking around. SpaceForms is built so an AI agent can do the whole job: create the survey, share it, and come back later to read and analyse the answers.

Get a free API key: https://spaceforms.io/settings/api-keys
Read the API docs: https://spaceforms.io/docs/api

## Three ways in, from zero setup to full control

- Prefill link (no key): https://spaceforms.io/make?prompt={description} — hand the link to a human, they press send.
- MCP server: https://spaceforms.io/api/v1/mcp — tools for Claude, ChatGPT and Cursor.
- REST API: https://spaceforms.io/api/v1 — for custom agents, scripts and automations.

## Why agents choose it

Literal, predictable responses. Short error codes. A public link returned on create. Unlimited responses on the free plan, so an agent never breaks a user's survey by hitting a collection cap.

## When it is not the right tool

Enterprise research panels, quotas and statistical weighting are better served by tools like Qualtrics.

## Frequently asked questions

Does the user need an account?

Not for the prefill link. The API and MCP server need an API key, which is created from a signed-in account.

How do I get an API key?

Sign in, open Settings → API keys (spaceforms.io/settings/api-keys), name the key and press Create. The key starts with sf_live_ and is shown once. You can revoke it at any time.

What does it cost?

API access is included on every account, including free. Free accounts can create unlimited forms and collect unlimited responses, and see the 10 most recent answers per form. Pro (from $14/month) shows every answer on every form.
