Why MantAPI

One vendor for every model your teams use

A managed gateway that unifies access, guarantees reliability, and takes the multi-vendor burden off your platform team.

One integration, every model

Connect to MantAPI once and reach Claude, GPT, Gemini, Grok, and every major model through a single OpenAI-compatible endpoint. No per-vendor contracts, no per-vendor maintenance.

Reliability built for procurement, legal & DevOps

High-availability architecture with automatic failover and redundancy across providers. When one provider has an incident, your traffic routes around it — before your on-call team wakes up.

Built for enterprise security & compliance

SSO, role-based access control, and full request-level audit logs — with a compliance program built for security review, not just the sign-up flow.

Intelligent routing & automatic failover

Traffic is distributed across providers by latency, cost, and availability in real time. Define fallback chains and model-level policies, and let MantAPI own the complexity your platform team shouldn't.

Full observability & consolidated billing

Per-team usage dashboards, request-level audit logs, cost attribution by model and project, and a single invoice. One vendor relationship instead of twelve.

Dedicated support, day one to production

Every enterprise account gets a dedicated solutions engineer for onboarding, integration review, and escalation. Reachable — not just a ticket queue.

Security & compliance

Security and data practices built for enterprise review

MantAPI is designed for organizations where procurement, legal, and security teams are part of every vendor decision.

You own your data

We never use your requests or outputs to train models. Your traffic stays yours.

Full audit logging

Request-level logs and usage attribution by model, project, and team — ready for your security and finance reviews.

SSO and role-based access

Sign in through your identity provider, with role-based controls across teams, projects, and model tiers.
