robot-resources 0.2.0

Robot Resources Python SDK — smart model selection for AI agents. Thin client over /v1/route + opt-in auto-attach for the Anthropic SDK (set RR_AUTOATTACH=1).

Python SDK for Robot Resources — smart model selection for AI agents.

Install

pip install robot-resources

Quick start

from robot_resources.router import route

decision = route("write a python function that reverses a string")
print(decision["selected_model"])   # e.g. 'claude-haiku-4-5'
print(decision["savings_percent"])  # e.g. 68.0

Filter by what providers you have keys for

decision = route(
    "summarize this article",
    available_providers=["anthropic", "openai"],
)

Or pass an explicit allowlist of model names:

decision = route(
    "what is the capital of France",
    available_models=["claude-haiku-4-5", "gpt-5.4-mini"],
)

Reusing the client across many calls

For agents that route many prompts in a single process (LangChain, LlamaIndex, CrewAI), instantiate RouterClient once and reuse it — connection pooling cuts per-call latency by ~3x.

from robot_resources.router import RouterClient

with RouterClient() as client:
    for prompt in prompts:
        decision = client.route(prompt)
        # ... call your LLM provider with decision['selected_model']

Authentication

Set RR_API_KEY in your environment, or pass api_key=... per call.

export RR_API_KEY=rr_live_yourkey...

Don't have a key? Run npx robot-resources to get one provisioned anonymously.

Errors

The client raises typed exceptions:

• AuthenticationError — bad or missing API key (HTTP 401)
• RateLimitError — too many requests for this API key (HTTP 429)
• ServerError — platform 5xx after retries exhausted
• RouterError — base class for any other platform error

Network errors retry with exponential backoff (3 attempts: 0.5s, 1s, 2s).

Override the endpoint

decision = route("hello", endpoint="http://localhost:8787/v1/route")
# or via env var: RR_PLATFORM_URL=https://staging.robotresources.ai

Future tools

This package is the umbrella SDK for Robot Resources. Today it exposes routing under robot_resources.router. As we expose more tools via HTTP API, they'll land as additional submodules under the same package — pip install robot-resources covers them all.

About the package name

The PyPI name robot-resources-router was used 2026-04-26 as a redirect stub when the legacy Python daemon was deprecated. This SDK is a different package: robot-resources (singular). If you previously had robot-resources-router pinned, leave that pin alone — it's deprecated and won't change.
