The API
Built for agent workloads.
A shared model layer for your applications, tools, and agents.
Choose a model per request
Use a fast model for everyday work and a reasoning model for the difficult parts. Your agent keeps the same API connection.
Connect your agent programs
Give your agent access to the model catalog through one REST API. Authenticate with a workspace key and send your requests.
Keep track of usage
Review token usage, latency, and spending in one place. Set limits on keys by model, budget, or environment.
Stream responses
Receive output as it is generated through server-sent events. The same connection supports conversation and tool calls.
Test before you choose
Try the same task with different models. Compare the result and the cost before deciding what runs in your agent.
Every provider, one connection
Access OpenAI, Google, Anthropic, Moonshot, GLM, DeepSeek, xAI, Meta, and Qwen without maintaining a separate integration for each provider.
PlaygroundTest every model before
Test every model before
you commit a line.
Try a prompt, switch models, and compare the response. Find the right model before connecting it to your agent program.

What does OpenAPI do?
OpenAPI proxies requests to model providers through one API at api.openapi.shop/v1. Your agent program chooses a model for each request, and OpenAPI handles the provider connection.
Can I connect it to my agent program?
Yes. The API accepts Chat Completions requests and uses bearer-token authentication. Create a workspace key, configure your agent's API connection, and select a model ID from the catalog.
Which models can I use?
The catalog includes 28 models from OpenAI, Google, Anthropic, Moonshot, GLM, DeepSeek, xAI, Meta, and Qwen. The models page lists model IDs, context windows, and available rates.
Does it support streaming and tools?
Yes. Set stream to true for server-sent events. The API also accepts tool definitions, image inputs, and structured output as described in the documentation.
What happens to my data?
Request and response bodies are not retained by default. Billing and abuse-prevention metadata is retained for 30 days. Providers process requests under their own policies; zero-retention routing is available on paid plans.
Give your agent more to work with.
Create a key and connect to the model catalog.
