A marketplace of ready-to-use APIs and MCP servers for apps and AI agents
Listed APIs speak the Model Context Protocol, so they can be attached as tools to AI agents and used by MCP-capable clients like Cursor, Claude Desktop and Continue.
Test endpoints live against models such as Claude and GPT to see how an API behaves in an actual agent-driven conversation before you commit to an integration.
Register a base URL and credentials, define inputs and outputs with a guided wizard, and deploy an MCP server that serves both humans and agents.
API Hub handles hosting, subscriptions, billing and revenue sharing, so API owners can focus on the product instead of payment plumbing.
Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
