API Reference

List the models available to your key.

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

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, o3, gpt-oss-120b. (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-5.3-codex (Azure does not expose chat completions for it). Use your SDK's client.responses.create(...) or POST directly.

curl https://api.aiforbiz.email/v1/responses \
  -H "Authorization: Bearer $AIFORBIZ_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.3-codex",
    "input": "Write a Python function that reverses a linked list."
  }'

Generate an image. Models: gpt-image-2 (newest flagship), gpt-image-1.5, or gpt-image-1. Returns base64 image data.
Long calls: high-quality / large images can take 2–3 min. The proxied host caps at ~100s (HTTP 524); for those, use the direct host https://direct-api.aiforbiz.email/v1 and set your client timeout to ≥ 300s.

curl https://api.aiforbiz.email/v1/images/generations \
  -H "Authorization: Bearer $AIFORBIZ_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2",
    "prompt": "A watercolor fox in a misty forest",
    "size": "1024x1024",
    "n": 1
  }'

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 "[email protected]" \
  -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")
