First successful request
For a new integration, use this path:- Create an API key in the dashboard.
- Send one request to a current text model.
- Read the model output from the response.
- Move into the SDK, routing, or production guide that matches your next step.
First request
Choose your path
If you already have an integration or toolchain, start from the closest match instead of reading the docs from the top.I'm coming from OpenAI
Keep the OpenAI-compatible shape, swap the base URL and key, and verify model support.
I'm coming from OpenRouter
Move your existing routing setup over with parity checks and staged rollout guidance.
I'm sending raw HTTP requests
Start from cURL and the Responses API, then move into the endpoint reference when needed.
I'm using the TypeScript SDK
Use the TypeScript client as your main entry point for Responses, chat, images, audio, and more.
I'm using the Python SDK
Start from the Python client if your integration lives in scripts, workers, backends, or notebooks.
I'm using the AI SDK
Connect Vercel AI SDK apps to Phaseo without rebuilding your prompt or model flow.
I'm using Codex or Claude Code
Set up the gateway, Docs MCP, and coding-agent integrations from one place.
I just need examples
Jump straight to copy-paste requests and sample projects if you already know the basics.
Common jobs
Choose the job closest to what you need right now.Make my first request
Start with one successful text request, then learn where to read output and debug failures.
Use an SDK
Pick the client SDK that matches your stack and start from real wrapper examples.
Connect a coding agent
Set up Codex, Claude Code, OpenCode, or Docs MCP against Phaseo.
Migrate an existing integration
Move from OpenAI, OpenRouter, Anthropic, Vercel, LiteLLM, or another gateway.
Control routing and providers
Choose provider order, ranking, regional offers, presets, and failover behavior.
Run async jobs
Build video, music, and batch workflows with polling, webhooks, and status retrieval.
Core pages
Quickstart
The shortest path from signup to first successful request.
API Reference
Base URL, auth, endpoint families, and endpoint-by-endpoint request details.
Examples
Copy-paste requests and sample projects across common workflows.
Cookbook
Scenario-driven recipes for routing, presets, async jobs, search, and agent workflows.
Authentication
Key format, bearer headers, and common auth mistakes.
Error Handling
Understand failed requests quickly and fix the common causes.
If you are using agents
Phaseo is set up to work well with coding agents and AI tools, not just humans reading docs in a browser. Start here:Docs MCP
Let Codex, Claude Code, Cursor, or VS Code search the live Phaseo docs while they work.
skill.md
Capability summary for agents that need to understand what Phaseo can do and how requests work.
Integrations
Set up coding tools and editor workflows around the gateway.
Agent SDK
Build tool-using, gateway-backed agent loops across the supported SDK languages.
Explore models and providers
Use the data surfaces when you need to choose before you build:Browse Models
Find models, pricing, context windows, capabilities, and provider offers in one place.
Compare Models
Compare performance, cost, and metadata side by side before you commit to one route.
