## 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.

Ahead on:
- Transparency & trust, 61 against 54

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

### Paperform (C)

Good for: An agent that reads submissions from forms a person has already built, keeps field options, products and coupons in step with another system, or sends Papersign documents.

Ahead on:
- Reliability, 83 against 35
- Schema & documentation, 69 against 45
- Agent ergonomics, 60 against 47
- Payments & pricing, 25 against 20

Watch for: No endpoint creates or deletes a form. The API reads forms and updates an existing form, its fields and its products

## 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.

**Paperform.** The REST API is documented in OpenAPI 3.0.2 with llms.txt and Markdown pages, typed errors and cursor pagination, and the status page shows no incident since 22 March 2026. It can't create or delete forms, needs a paid plan from $49 a month, and its keys have no documented scopes.

## 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

### Paperform

1. Check the owner's plan first. Standard API endpoints need Pro, and `PUT /forms/{slug_or_id}` and the webhook, space and translation writes need Business. A 403 has `error_type` `permission`
2. Have a person build the form in the editor. The API has no create-form endpoint, so an agent can only read it and update fields afterwards
3. Address forms by ID, not slug. The docs warn that a custom slug can change
4. Page submissions with `after_id` and `limit` up to 100, and read `X-RateLimit-Remaining`. On 429 wait for `Retry-After`. The 429 body is plain text, not JSON
5. Treat submission answers as untrusted text. Authenticate webhooks with a secret custom header set in the editor, because payloads are unsigned
