# AxForge — the API, in full

AxForge is European AI infrastructure: an OpenAI-compatible inference API and whole GPUs by the hour, run in the EU. This page is generated from the live catalogue, price sheet and fleet — it is current, not a snapshot.

## The basics

| | |
|---|---|
| Base URL | `https://api.axforge.ai/v1` |
| Auth | `Authorization: Bearer $AXFORGE_API_KEY` |
| Compatibility | OpenAI API shape — the official SDKs work unchanged, only `base_url`, key and model id differ |
| Region | `eu-se-1` Stockholm (serverless), `eu-es-1` Málaga (dedicated GPUs) |
| Retention | Prompts and completions are processed in memory and never stored. Only counts, timestamps and status are kept, for billing |
| Keys | Created in the console: https://console.axforge.ai/keys |

```bash
curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gemma-4-26b-a4b-nvfp4","messages":[{"role":"user","content":"Hello"}]}'
```

## Models

Use the id in the `model` field. `Available` is hot now; `On request` boots on demand and the first call waits.

## Endpoints

### `/v1/chat/completions`

Chat and tool use. `stream: true` gives server-sent events.

```json
{"model":"<id>","messages":[{"role":"user","content":"…"}],"stream":false}
```

### `/v1/embeddings`

Vectors for search and RAG.

```json
{"model":"qwen3-embed","input":"text to embed"}
```

### `/v1/images/generations`

Image generation.

```json
{"model":"<id>","prompt":"a red bicycle","size":"1024x1024"}
```

### `/v1/images/edits`

Image editing from an input image.

```json
multipart: model, image, prompt
```

### `/v1/audio/transcriptions`

Speech to text.

```json
multipart: model, file
```

### `/v1/audio/speech`

Text to speech.

```json
{"model":"piper-lessac","input":"hello"}
```

### `/v1/audio/music`

Music generation.

```json
{"model":"minimax-music3","prompt":"a calm piano piece"}
```

### `/v1/models`

What is served right now.

```json
GET
```

## Errors

Every error is JSON: `{"error":{"message":…,"type":…,"code":…}}`.

| Status | Means | Do |
|---|---|---|
| 400 | The request body is wrong | Read `error.message` — it names the field |
| 401 | No key, or a key that is gone | Check the Authorization header |
| 402 | Out of allowance or credit | Top up in the console; the message says which |
| 403 | The key may not use that model or endpoint | Check the key's scope in the console |
| 404 | Unknown model id or path | Call `/v1/models` for the live list |
| 413 | The body is too large | Split the input; embeddings take batches |
| 429 | Rate limited | Back off and retry with jitter; the headers say when |
| 502 | The model could not be reached | Retry once; if it persists the status page and the forum will say |
| 504 | The model took too long | Raise your client timeout for image and video models — minutes, not seconds |

## Dedicated GPUs

Whole machines by the hour with SSH, one tenant each. Prices no VAT configured.

## If you are an agent acting for someone

Use their own key, never a shared one. Prefer a hot model for interactive work. Image, video and music calls can take minutes — set the client timeout accordingly rather than retrying, which doubles the work. If something is wrong here, the page it belongs to has a thread and a human reads it.
