Humanform API

Terms of Service

Last updated: July 5, 2026

These Terms of Service ("Terms") govern your access to and use of Humanform, a product of Fieldwork ("we," "us," "our"), including humanform.app, dashboard.humanform.app, api.humanform.app, and the Humanform MCP server (together, the "Service"). By creating an account or using the Service, you agree to these Terms.

1. The Service

Humanform provides an API that returns statistically modeled anthropometric (body measurement) predictions based on parameters you supply (measurement type, gender, age, percentile, and country). Predictions are population-level statistical estimates derived from reference datasets, not measurements of any specific individual.

2. Accounts

You must create an account to use the Service. You are responsible for maintaining the confidentiality of your account credentials and API keys, and for all activity that occurs under your account. Notify us immediately if you suspect unauthorized use of your account or API key.

3. Credits and Billing

  • Access to /v1/predict beyond the free tier requires purchasing credits via Stripe.
  • A free tier of 10 predictions per rolling 24-hour period is available once purchased credits are exhausted, or for accounts that have not purchased credits.
  • Credits are consumed only on successful predictions; validation errors, unrecognized parameters, and failed requests do not consume credits.
  • Credits are non-refundable except where required by applicable law, or at our discretion.
  • We reserve the right to change pricing for future credit purchases at any time; changes do not affect credits already purchased.

4. Acceptable Use

You agree not to:

  • Use the Service to violate any applicable law or regulation
  • Attempt to circumvent rate limits, free tier limits, or credit-based access controls
  • Reverse engineer, scrape, or systematically extract the underlying prediction models or reference datasets for the purpose of building a competing dataset or service
  • Share, resell, or sublicense API keys to third parties outside your own organization without our consent
  • Use the Service in any safety-critical context (e.g., medical devices, life safety equipment, or regulatory certification) without independent validation; predictions are statistical estimates and are not a substitute for direct measurement or professional judgment

We reserve the right to suspend or terminate accounts that violate these Terms.

5. Intellectual Property

We retain all rights, title, and interest in the Service, including the underlying prediction models, reference datasets, and software. You retain ownership of any content or products you create using predictions returned by the Service, subject to the accuracy disclaimers in Section 6.

6. Disclaimers

THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. Predictions are statistical estimates based on population-level reference data and are provided for design and engineering guidance only. We do not warrant that predictions are accurate for any specific individual or use case. You are solely responsible for independently validating predictions before relying on them in any context where accuracy is critical.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, FIELDWORK SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUE, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE 12 MONTHS PRECEDING THE CLAIM.

8. Service Availability

We aim to keep the Service available and reliable but do not guarantee uninterrupted access. We may modify, suspend, or discontinue any part of the Service at any time, with reasonable notice where practicable.

9. Termination

You may stop using the Service and delete your account at any time via your dashboard settings. We may suspend or terminate your access for violation of these Terms, non-payment, or extended inactivity, with notice where practicable.

10. Changes to These Terms

We may update these Terms from time to time. We will post the updated version on this page with a revised "Last updated" date. Continued use of the Service after changes constitutes acceptance of the updated Terms.

11. Governing Law

These Terms are governed by the laws of England and Wales, without regard to conflict of law principles.
