OpenAI Select Partner · OpenAI Partner Network
SperaxOS is an OpenAI Select Partner
SperaxOS has joined the OpenAI Partner Network at the Select tier. The open-source AI agent workspace for DeFi runs on OpenAI models and exposes its tools to OpenAI platforms, so agents can research markets, read on-chain data, and act with guardrails.
Why it matters
Frontier models, DeFi-native tools
Agents reason with OpenAI models and act through SperaxOS tools: market data, on-chain reads, yields, risk scoring, and news across Arbitrum and other EVM chains.
Guarded execution
Every on-chain action passes the SperaxOS risk guard before it is signed: spend limits, slippage bounds, MEV protection, and human approval for anything that moves funds.
Open source
SperaxOS is Apache-2.0 and self-hostable. Bring your own OpenAI or Azure OpenAI key and run the whole workspace on your own infrastructure.
What runs on OpenAI
Shipped today, open source
Azure OpenAI
Teams on Azure can route the same agents through their own Azure OpenAI deployments, keeping data residency and billing inside their tenant.
OpenAI-format tool definitions
Every SperaxOS tool exported as an OpenAI function-calling array. Drop it straight into the `tools` parameter of a Chat Completions or Responses API request.
OpenAPI spec for GPT Actions
One OpenAPI 3.1 document covering the Intel, Data, Agent, and ERC-8004 APIs. Import it as a GPT Action, or into any OpenAPI-aware agent framework.
Connect SperaxOS MCP servers
Public, read-only, Streamable HTTP. No SperaxOS account needed.
Add any of these servers as a remote MCP tool in the OpenAI Responses API, the Agents SDK, or ChatGPT connectors. The full index with live tool schemas is at /webapi/mcp.
