APIPark
APIPark is an open-source LLM gateway and API developer portal for enterprises that need one place to call, govern, and bill AI models and internal APIs. It routes traffic to 200+ large language models through a single OpenAI-compatible endpoint, so teams stop wiring separate vendor SDKs for every model they add.
Where most API gateways only forward requests, APIPark also treats models and APIs as tradable assets. It bundles unified authentication, approval workflows, recharge billing, multi-level distribution, and profit reporting so platform teams can sell surplus model capacity or package business APIs without building a separate marketplace stack.
Platform engineers and AI teams use it to set per-tenant quotas, rate limits, and masking rules before production traffic hits upstream models. API managers get portals for publishing APIs, tracking usage, and approving access requests. The Community Edition covers core gateway and portal features; the Enterprise Edition adds advanced governance, runtime statistics, and premium support.
Routes 200+ LLMs through one OpenAI-compatible API signature so existing client code needs no vendor-specific rewrites
Deploy the gateway and developer portal in about 5 minutes with a single command-line install
Load balancing distributes requests across LLM instances to keep failover and throughput predictable under load
Built-in API billing tracks per-user consumption so teams can meter and monetize internal or partner API access
Fine-grained quotas cap daily or monthly spend by amount, tokens, or call counts to block runaway model usage
Data masking engine flags and masks sensitive fields in request and response payloads for compliance workflows
One OpenAI-compatible endpoint covers 200+ LLMs without per-vendor SDK work
Community Edition is open source with a documented 5-minute command-line deploy
Combines gateway routing with portal publishing, approvals, and billing in one product
Per-tenant quotas and rate limits help control model spend before overages hit upstream bills
Semantic caching is marked coming soon, so latency savings from cache are not available yet
Community Edition lacks runtime statistics, cost accounting, and several advanced security plugins
Enterprise Edition pricing is not published and requires a sales contact for full feature access
What is APIPark?
APIPark is an open-source LLM gateway and API developer portal. It connects teams to 200+ language models through one managed endpoint while handling authentication, quotas, billing, and API publishing in the same platform.
Is APIPark free to use?
APIPark offers a free Community Edition with core gateway, portal, and governance features for SMEs. The Enterprise Edition adds advanced statistics, plugins, and support services and requires contacting APIPark sales.
How does APIPark connect multiple LLMs?
APIPark exposes an OpenAI-compatible chat completions endpoint. Teams point existing OpenAI client code at APIPark and switch models by changing the model name in the request without rewriting application integrations.
How fast can APIPark be deployed?
APIPark can deploy its LLM gateway and developer portal in about 5 minutes using a single command-line install workflow documented on the APIPark install page.
Does APIPark support API monetization?
Yes. APIPark includes built-in API billing and recharge accounts so consumers pay once on the platform and call authorized models or business APIs with automatic per-call deduction.
How does APIPark protect sensitive data?
APIPark provides data masking that identifies and masks sensitive fields in LLM requests and responses. Teams also get identity authentication, traffic control, and encryption options in the Enterprise Edition.
