llmapi.aiAbout LLMAPI
LLMAPI is an LLM gateway that fronts every major provider behind one OpenAI-compatible endpoint, and its commercial argument is arithmetic rather than architecture: the same Claude, GPT, Gemini and DeepSeek calls, routed through a single account, at a lower bill. The compatibility choice does most of the integration work — a codebase already speaking the OpenAI API format changes a base URL rather than a client library — and from there the gateway adds the operational layer that raw provider keys never provide. Keys for every downstream provider live in one managed place instead of scattered across environment files, teams can be synced in a click with a unique API key issued per member, and per-key IAM and shared budgets stop a single runaway script from consuming a month of spend. The observability side reports requests, tokens, total spend and average cost per thousand tokens over seven- or thirty-day windows, broken down by provider and model so expensive outliers surface without a query, plus error rate, cache-hit rate and reliability trends. Because every provider sits behind the same interface, vendor lock-in disappears at the routing layer: switching models is a parameter change, not a migration. Over four hundred models are available. Enterprise commitments above $100K a month move to wholesale rates, BYOK, private VPC or on-premises deployment and custom SLAs, but the self-serve path is a credit top-up with the tier discount applied automatically and no contract to negotiate.
