routerai

Python wrapper for the RouterAI API — unified access to 450+ AI models (OpenAI, Anthropic, Google, DeepSeek, Qwen, ...) with ruble pricing.

Features

• OpenAI-compatible chat completions with sync + async support (one client instance supports both; transports are kept separate)
• Parsed responses: content, reasoning, tool calls, alternatives, token usage and cost in rubles (Decimal)
• Streaming (SSE) with per-chunk deltas; once a successful response stream is opened no automatic retries happen (even if 0 chunks arrived), mid-stream failures raise a typed StreamInterruptedError
• Models catalog: listing, client-side search, grouping by capabilities (text, reasoning, vision, image/video/audio generation, speech, transcription, embeddings, rerank, tools)
• Post-hoc cost lookup by generation id (X-Generation-Id)
• Multiple API keys via a per-instance Registry (contextvar, thread/async safe)
• Images, video (polling), audio (TTS/STT), embeddings, rerank, API-key and team management
• Zero-effort logging via the standard logging module (namespace routerai, keys masked)

Install

pip install routerai

Quickstart

from routerai import RouterAI

client = RouterAI(api_key="sk-...")  # or set ROUTERAI_API_KEY env var

result = client.chat.complete("deepseek/deepseek-v4-pro", "Привет!")
print(result.content)
print(result.cost_rub)  # Decimal, in rubles

Model catalog

client.models.all()                       # full catalog (cached, TTL by default 10 min)
client.models.search("claude", capabilities=["reasoning"], min_context=100_000)
client.models.by_capability("image")      # image generation models
client.models.grouped()                   # dict[Capability, list[Model]]
client.models.get("deepseek/deepseek-v4-pro").pricing.per_million("prompt")
client.models.endpoints("anthropic/claude-sonnet-5")  # providers + prices

Several API keys

from routerai import RouterAI, Registry

registry = Registry(main=RouterAI(api_key=A), personal=RouterAI(api_key=B))
registry["personal"].chat.complete(...)
with registry.using("main"):
    ...

Streaming

for chunk in client.chat.stream("openai/gpt-5.6-sol", "Расскажи сказку"):
    print(chunk.content, end="")

Speech-to-text

client.audio.transcribe("openai/whisper-large-v3", "voice.wav")      # format from suffix
client.audio.transcribe("openai/whisper-large-v3", raw_bytes, format="mp3")
for chunk in client.audio.speech_stream("x-ai/grok-voice-tts-1.0", "текст", voice="eve"):
    ...

Video lifecycle

from routerai import FrameImage, ImageReference

task = client.videos.create(
    "bytedance/seedance-2.0",
    "Персонаж идёт через осенний лес",
    frame_images=[FrameImage(url="https://example.com/first.png", frame_type="first_frame")],
    # or reference-to-video: input_references=[ImageReference(url=...)]
)
task.wait(timeout=600, interval=5)      # absolute deadline, incl. retries
task.save("video.mp4", index=0)         # streaming download, atomic rename
await task.asave("video.mp4")           # async variant, cancellation-safe

# webhooks: verify HMAC over the raw body with your api key
from routerai.webhooks import verify_video
data = verify_video(raw_body, signature, api_key, timestamp, max_age_seconds=300)

Async

result = await client.chat.acomplete("deepseek/deepseek-v4-pro", "Привет!")
async for chunk in client.chat.astream(...):
    ...
await client.aclose()

Sync and async transports live in separate slots, so one instance can serve both modes. Note the lifecycle: close() closes the sync connection pool, await aclose() closes the async one. If a single instance was used from both modes, call both. External transports injected via http_client/async_http_client are never closed by the library.

Configuration

Retries honour the Retry-After header. Safe methods (GET/HEAD) are retried on 429/5xx; unsafe methods only on 429 by default.

The extra parameter is an escape hatch for provider-specific request fields: it can never override library-managed keys (model, messages, stream, ...) — colliding keys raise ValueError.

Errors

Logging

import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger("routerai").setLevel(logging.DEBUG)  # API keys are masked
