API Reference

Public, machine-readable base prices. No API key is required. Add ?model=gpt-5.6-sol to return one model. Token prices are USD per 1M tokens; cached input and long-context rates are included when configured. Variable image/audio models identify their billing dimension without inventing a fixed token price.

Chat and reasoning. Models: gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna, gpt-5.5, gpt-chat-latest, gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, gpt-5.3-codex, gpt-5, gpt-5-mini, gpt-5-nano, o3, gpt-oss-120b, kimi-k3. (gpt-5.3-codex is a Responses-API model: call it via /v1/responses below; the OpenAI-style /v1/chat/completions is auto-translated, but an Azure-SDK .chat.completions call returns 404.)

curl https://api.aiforbiz.email/v1/chat/completions \
  -H "Authorization: Bearer $AIFORBIZ_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [
      {"role": "user", "content": "Summarize relativity in two sentences."}
    ],
    "max_completion_tokens": 500
  }'

Responses API. Required for gpt-6-astra and gpt-5.3-codex (Azure does not expose chat completions for these models). Use your SDK's client.responses.create(...) or POST directly.

Built-in image_generation tool. gpt-5.6-sol, gpt-5.6-terra and gpt-5.6-luna can generate and edit images inline, using the same request shape as OpenAI. Set the tool's model to gpt-image-2.5-flare or gpt-image-2.5-sunburst; action, quality, size, background, output_format, moderation and max_tool_calls all apply. The image arrives as base64 in an image_generation_call output item, and the image tokens are reported separately under tool_usage.image_gen and billed at the GPT Image 2.5 rates above, on top of the orchestrating model's own tokens.
Required: use https://direct-api.aiforbiz.email/v1 for image-generating requests and set your client timeout to ≥ 300s. stream: true is not supported together with this tool.

Generate an image. Models: gpt-image-2.5-flare and gpt-image-2.5-sunburst (12 requests per minute each; access requires explicit authorization), gpt-image-2 (up to 56 requests per minute), gpt-image-1.5, or gpt-image-1. Returns base64 image data.
Required: use https://direct-api.aiforbiz.email/v1 for every image-generation request and set your client timeout to ≥ 300s.

curl https://direct-api.aiforbiz.email/v1/images/generations \
  -H "Authorization: Bearer $AIFORBIZ_KEY" \

  }'

Edit a PNG or JPEG hosted at a public HTTPS URL with gpt-image-2, gpt-image-2.5-flare, or gpt-image-2.5-sunburst. Send JSON with exactly one of image_url or image_urls. The gateway authenticates the key before downloading, blocks private/internal destinations, validates the image, and then sends its bytes through the normal LiteLLM/Azure edit path.
Required: use https://direct-api.aiforbiz.email/v1 and set the client timeout to ≥ 300s.

curl https://direct-api.aiforbiz.email/v1/images/edits \
  -H "Authorization: Bearer ***" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2",
    "image_url": "https://cdn.example.com/input.png",
    "prompt": "Change the background to a beach",
    "quality": "medium"
  }'

  -F quality=low -F size=1024x1024

Use gpt-image-2.5-sunburst for Sunburst. Omit response_format. Existing multipart uploads remain supported on the same endpoint. URL inputs must use HTTPS on port 443, resolve only to public addresses, return a valid PNG/JPEG, and stay within the 20 MiB combined input limit. Optional URL fields: image_urls (up to four images) and mask_url. These models return data[].b64_json; Azure does not provide URL output. The JSON adapter returns one edited image per request.

Adapter errors: 400 unsafe/unreachable URL, 401/403 auth/access, 408 download timeout, 413 size/pixels, 415 invalid image, and 429 budget/rate/concurrency. Azure edit and safety errors pass through.

Vector embeddings. Models: text-embedding-3-small, text-embedding-3-large, text-embedding-ada-002.

curl https://api.aiforbiz.email/v1/embeddings \
  -H "Authorization: Bearer $AIFORBIZ_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "text-embedding-3-large",
    "input": "the quick brown fox"
  }'

Speech-to-text. Model: whisper. Multipart upload of an audio file; returns {"text": ...}.

curl https://api.aiforbiz.email/v1/audio/transcriptions \
  -H "Authorization: Bearer $AIFORBIZ_KEY" \
  -F "file=@meeting.wav" \
  -F "model=whisper"

Your key's budget and running spend, so you can show remaining balance in-app without opening the dashboard. Call it with just your key and no parameters; it returns only your own key. Note this route is at the root, not under /v1.
Budget left = max_budget − spend (USD). A null max_budget means the key is uncapped.

curl https://api.aiforbiz.email/key/info \
  -H "Authorization: Bearer $AIFORBIZ_KEY"

# → {"key":"...","info":{"spend":0.42,"max_budget":100.0,"soft_budget":null, ...}}
# remaining budget = max_budget - spend = 99.58 USD

# Python: remaining budget in a couple of lines
import requests
info = requests.get("https://api.aiforbiz.email/key/info",
                    headers={"Authorization": f"Bearer {AIFORBIZ_KEY}"}).json()["info"]
remaining = None if info["max_budget"] is None else info["max_budget"] - info["spend"]
print(remaining, "USD left")
