X-AIO Developer Documentation
One starting point for models, AI tools, APIs, MCP, subscriptions, usage, and security.
X-AIO gives developers a unified AI workspace. Choose from open-source and closed-source models in one console, connect ready-made AI tools, or build applications and workflows with APIs and MCP.
The model catalog, context limits, available plans, and billing rules change over time. Use the live console as the source of truth for model availability and pricing.
Start with your task
Model Center
Compare open-source and closed-source flagship models by capability, context window, and current Credit price.
Tokens Plan
Connect Claude Code, Cursor, Cline, Roo Code, OpenCode, Goose, and other coding tools to a developer-focused subscription. Open Tokens Plan
API reference
Explore model, chat, embedding, reranking, and image generation endpoints, then complete your first request. Browse the API reference
AI tool integrations
Find coding, chat, productivity, learning, and agent setup guides in one place. Browse AI tools
Choose an integration path
AI tool integrations: choose a ready-made tool
To use models in an existing tool, start with AI Tool Integrations and choose a chat client, AI coding tool, productivity app, or agent platform by purpose.
Tokens Plan: choose a plan for coding workflows
If most of your work happens in an IDE or terminal, review the Tokens Plan overview, then choose a guide under AI Coding Tools. Tokens Plan allowance is intended for designated or approved coding tools; use the general API service for application backends and other API workloads.
API: add models to your product
Start with the API documentation, inspect the available models, and choose the chat, embedding, reranking, or image generation endpoint that matches your use case. The live Model Center lets you compare context limits and input and output costs.
MCP: connect agents to external tools
Use MCP when an agent needs external data or tools. Choose a compatible client or agent platform under AI Tool Integrations, then check the relevant guide and version notes for MCP support.
Make your first request in three steps
- Choose a model or plan: review currently available open-source and closed-source models in the Model Center. For coding work, compare plans in the Subscription Store.
- Configure a tool or API: follow AI Tool Integrations or the API reference to set up your environment.
- Review usage and iterate: inspect request counts, tokens, Credits, and latency in Usage and Usage Details, then adjust your model or plan.
Plans, Credits, and billing
The console separates billing areas by purpose:
| What you need | Where to go |
|---|---|
| Tokens Plan subscription and available allowance | My Subscription |
| Trial, monthly, and add-on options | Subscription Store |
| Token and Credit consumption | Usage |
| Per-request records | Usage Details |
| Pay-as-you-go wallet balance | Wallet |
Tokens Plan, add-on packages, computing packages, and the pay-as-you-go wallet are separate billing sources. Allowance is deducted from Tokens Plan, add-on packages, and computing packages in that order. Input, output, and cache-read prices can differ by model. Check the current console for benefits, deduction rules, reset times, and limits; this page intentionally avoids price figures that may become outdated.
API key and account security
The documentation will never display or ask for your API key. Manage credentials in the console, keep them in local environment variables or a secure secret manager, and use placeholders in examples. Never commit real keys to a repository or expose them in logs or screenshots.
Account and help
Account settings
Manage account preferences and security settings. Never share login credentials or API keys publicly.
