→Welcome to Naxios
Naxios provides the tools you need to build, test, and scale AI-powered applications with ease.
Start with the 5-minute quickstart to send your first API request and explore what's possible.

Quickstart
Send your first request in three steps: grab an API key, install an SDK, and call a model.
1. Get an API key
Sign up and copy your key from the dashboard. Store it as an environment variable; never commit it to source control.
2. Install the SDK
3. Make your first request
Authentication
All requests must include a Bearer token in the Authorization header. Your API key authenticates you to the API and authorizes access to your account's resources.
Using your key
Best practices
- Store keys in environment variables, secret managers, or your hosting provider's vault.
- Never commit keys to git or expose them in client-side code.
- Rotate keys periodically from your dashboard.
- Use scoped keys for production vs. development where possible.
Error responses
Missing or invalid keys return 401 Unauthorized. Suspended accounts return 403 Forbidden.
Models
Naxios offers a catalog of text, vision, and audio models through one unified API. Pricing is the same across providers.
| Model | Best for | Context |
|---|---|---|
naxios-pro | General-purpose reasoning and coding | 200K |
naxios-fast | Low-latency conversational flows | 128K |
naxios-think | Complex multi-step reasoning | 200K |
naxios-vision | Image understanding and OCR | 128K |
naxios-audio | Speech-to-text and synthesis | — |

API Reference
The API is REST over HTTPS, JSON in and JSON out, and is intentionally drop-in compatible with the OpenAI API — change the base URL and your key and most code will keep working.
Endpoints
POST /v1/chat/completions | Chat and reasoning |
POST /v1/completions | Text completion |
POST /v1/embeddings | Vector embeddings |
POST /v1/images/generate | Image generation |
POST /v1/audio/transcriptions | Speech-to-text |
GET /v1/models | List available models |
Streaming
Pass stream: true to receive Server-Sent Events for token-by-token output.
Agents
Agents let a model call tools, reason over their output, and chain actions together. You describe the tools with JSON schemas and Naxios handles the orchestration loop.
See the Guides for a step-by-step walkthrough of a research agent.
SDKs
Official SDKs wrap the REST API and add niceties like streaming iterators, retries with backoff, and typed responses.
- Python —
pip install naxios - JavaScript / TypeScript —
npm install @naxios/sdk - Go —
go get github.com/naxious-ai/naxios-go - HTTP — use any client with Bearer auth; see the API Reference
Guides
Recipe-style walkthroughs for common tasks. Each guide is self-contained and uses real, runnable code.
Rate Limits
Rate limits protect the platform and are enforced per API key. Your current tier and remaining quota are visible in the dashboard.
| Tier | RPM | Tokens / day |
|---|---|---|
| Tier 0 — Starter | 5 | Free tier |
| Tier 1 — Adaptive | 20 | 1M |
| Tier 2 — Pro | 45 | 4M |
| Tier 3 — Premium | 90 | 10M |
| Tier 4 — Enterprise | Custom | Custom |
When you exceed a limit the API returns 429 Too Many Requests with a Retry-After header. Back off, then retry.
