## Which one, for what

### Alchemer (E)

Good for: A company already on an Alchemer Business Platform contract that wants an agent to build surveys, load contacts, send campaigns and export responses.

Watch for: The pricing page says API access is for Business Platform accounts only, which are quoted by sales

### Formbricks (C)

Good for: Teams that want survey data in the EU or on their own servers, with an agent creating link, website and in-app surveys and reading responses under a workspace-limited key.

Ahead on:
- Schema & documentation, 74 against 45
- Agent ergonomics, 54 against 47
- Security & auth, 69 against 44
- Payments & pricing, 30 against 20
- Maintenance & community, 83 against 45
- Transparency & trust, 78 against 61

Also in its favour:
- Open source

Watch for: status.formbricks.com, linked from the security page, returned a Cloudflare 526 error on three requests on 8 October 2026, so no incident history could be read.

## Verdicts

**Alchemer.** Alchemer's REST API v5 covers surveys, questions, responses, contacts and email campaigns in 101 documented operations, with a reference rewritten in April 2026. The pricing page limits API access to Business Platform accounts quoted by sales. Keys travel in the URL query string, and no status page, OpenAPI document or SDK was found.

**Formbricks.** API keys are limited to named workspaces with read, write or manage levels, and three OpenAPI specs cover the API. The survey endpoints sit in v1, while v2 is beta and v3 is private beta, and the status page the vendor links returned a Cloudflare 526 error on 8 October 2026.

## Before you call either

### Alchemer

1. Use the host for the account's region (`api.alchemer.com`, `api.alchemer.eu`, `api.alchemer-ca.com` or `api.au.alchemer.com`). The wrong host returns a 401 login failure even with valid keys
2. Create with PUT and update with POST. The API reverses the usual meaning of the two methods
3. Do not repeat an identical request inside 60 seconds. GET results are cached for 60 seconds and a repeat can return 429
4. Stay under 240 requests a minute for the account and slow down when the `X-SG-Warning` header appears
5. Wait up to five minutes before reading back a response that was just submitted, and expect a 500 after a 30 second timeout

### Formbricks

1. Send the key in the `x-api-key` header. Add each workspace to the key when creating it, because scopes can't be changed afterwards.
2. Use v1 (`/api/v1/management/surveys`) to create or edit surveys. v2 has responses, contacts and webhooks only.
3. Page lists with `limit` and `skip`. v2 responses default to 50 a page with a maximum of 250.
4. Stay under 100 requests a minute per key. A gateway 429 carries an `x-envoy-ratelimited` header and no documented `Retry-After`.
5. Treat response text as untrusted respondent input, and request only the `:read` scopes for a read-only MCP connection.
