Terms of Service

Last updated: August 2026

Acceptance of Terms

By accessing or using the NMFC Classification API you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use the service.

API Access

Access to the API is granted via API keys issued upon registration. Each API key is associated with one account. You are responsible for keeping your API key confidential and for all activity that occurs under your account. One account per legal entity is permitted.

Acceptable Use

You may not resell or redistribute raw NMFC data obtained through the API. You may not attempt to exceed rate limits through automated retries, multiple accounts, or other means. You may not reverse engineer the API or attempt to access data outside the documented endpoints.

Subscription Plans & Billing

We offer Free, Starter, Pro, and Enterprise subscription tiers, available on either a monthly or annual billing cycle. Annual plans are charged once, in advance, for the full 12-month term. Additional API call capacity may be purchased as one-time top-up packs. All billing is handled through Stripe. Subscription fees are charged in advance at the start of each billing cycle and renew automatically until canceled.

No Refunds

All payments are final and non-refundable. This applies to monthly subscription fees, annual subscription fees, and one-time top-up pack purchases, in each case whether or not the purchased API capacity has been used.

  • We do not issue refunds or credits for partial billing periods, unused API calls, unused top-up balances, or accounts that are canceled mid-term.
  • Canceling an annual plan stops future renewals; it does not refund the current 12-month term, and access continues until the end of that term.
  • Downgrading a plan takes effect at the end of the current billing period. No refund or cash credit is issued for the difference.
  • We do not issue refunds for service interruptions, changes to the API, or changes to third-party source data.

A Free tier is available so you can evaluate the API before purchasing, and we encourage you to do so. This section applies to the maximum extent permitted by applicable law; where mandatory consumer-protection law grants you a non-waivable refund right, that law prevails.

Chargebacks

If you dispute a charge with your card issuer, we may suspend or terminate your account and revoke API access immediately. Please contact support@freightapis.dev first — most billing questions can be resolved directly.

Rate Limits & Quotas

Each plan includes a monthly API call quota. Annual plans receive the same monthly quota, refreshed each month of the annual term — they are not a single pooled yearly allowance. Unused calls do not carry over from one month to the next. When your quota is exhausted the API will return 429 Too Many Requests responses until the next monthly refresh or until you purchase a top-up pack. Top-up pack balances never expire and are consumed after the monthly quota is depleted.

Data Accuracy

NMFC classification data is sourced from official NMFC publications. We make best-effort attempts to keep the data current and accurate. However, the API data is provided for informational purposes only and does not constitute legal or regulatory advice. Always verify classifications with the official NMFC publication for compliance-critical decisions.

Intellectual Property

The NMFC classification data is owned by the National Motor Freight Traffic Association (NMFTA). The API service, including its software, design, and documentation, is owned by us. Nothing in these terms grants you ownership rights over either.

Termination

We reserve the right to suspend or terminate API access for violations of these terms, abuse of the service, or non-payment. You may cancel your account at any time from your account settings; access continues until the end of the current billing period. Cancellation stops future charges; fees already paid are not refunded (see No Refunds above).

Limitation of Liability

The service is provided "as is" without warranty of any kind, express or implied. To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, or consequential damages arising from your use of the API.

Changes to Terms

We may update these Terms of Service at any time. Continued use of the API after changes are posted constitutes acceptance of the updated terms. We will notify registered users by email for material changes.
