About mintfax

mintfax is an outbound fax API for engineering teams building B2B SaaS in regulated industries. We provide a modern API surface (REST, JSON, OpenAPI 3.1, signed webhooks, idempotency keys) and healthcare-grade compliance posture (BAA on every paid tier, AES-256 at rest, TLS 1.2+ in transit, per-workspace immutable audit log) - without the enterprise plans, seat licensing, or procurement cycles that competing fax APIs make customers absorb.

The product runs on an always-on AWS-shaped transaction path: API Gateway, an ingest Lambda, DynamoDB for hot state, SQS for queueing, and S3 for fax document staging. The application layer (control panel, billing, carrier orchestration) is a Laravel application that submits faxes to upstream carriers - InterFax (Upland) at first, with a second carrier active/active in evaluation. Customer integrations talk to one stable mintfax API surface; the carrier abstraction is internal.

Operating commitments

mintfax is the same API and the same compliance posture across every paid tier. There are no premium-tier features. There are no enterprise-only capabilities. The commitments below apply to every customer, on the free sandbox and on every paid tier.

• BAA on every paid tier. Free, self-serve, signed via DocuSign in your dashboard.
• Encryption. AES-256 at rest. TLS 1.2 minimum in transit, with TLS 1.3 on customer-facing endpoints.
• Per-workspace immutable audit log. Retained for the lifetime of the workspace; exportable as JSON or CSV.
• Signed webhooks. HMAC-SHA256 with timestamp replay protection on every callback.
• Idempotency keys. On all POST endpoints, with 24-hour key TTL.
• Built-in retries. Default 3 attempts with exponential backoff; configurable up to 8 per submission.
• Stable error taxonomy. Mintfax-owned error codes with actionable next-step hints; raw carrier codes retained for support.
• OpenAPI 3.1 spec and llms.txt discoverable at predictable URLs.
• Email response within one business day, faster on real outages.
• No seat licensing, no monthly minimums, no API gating. Per-page pricing applies on every paid tier.

Compliance

mintfax is HIPAA-aligned by design and operates against the 2026 HIPAA Security Rule requirements. Free BAA on every paid tier. AES-256 at rest, TLS 1.2+ in transit. SOC 2 Type II audit kickoff scheduled for Q3 2026. Full posture, including subprocessors, retention modes, and the BAA template, is on our compliance page.
