blockrun-llm-vip 0.1.0

Drop-in Anthropic & OpenAI Python SDK clients for BlockRun — genuine native passthrough (real signatures, system_fingerprint, native structure) with x402 USDC micropayments on Base. No model substitution, no response reshaping.

blockrun-llm-vip

Genuine native passthrough for Anthropic and OpenAI through the BlockRun gateway — pay per call in USDC (x402) on Base, with zero model substitution and zero response reshaping.

Unlike a normal aggregator, these clients subclass the official anthropic and openai Python SDKs and only swap the transport (to add x402 payment) and the base URL. The gateway returns the upstream provider's response verbatim, so the official SDK parses the real signals:

• Claude: real thinking-block signature, native content[] (text / thinking / tool_use), usage.cache_creation_input_tokens / cache_read_input_tokens, native signature_delta streaming — routed to Anthropic's native /v1/messages.
• GPT: native id (chatcmpl-*), system_fingerprint, usage.*_tokens_details, honest response_format (JSON mode) + stop + nested errors. gpt-4o / gpt-4o-mini are served OpenAI-direct.

A Claude / OpenAI relay detector (e.g. cctest.ai) sees a direct upstream call.

Install

pip install blockrun-llm-vip

Use — it's a drop-in

from blockrun_llm_vip import Anthropic, OpenAI

# Claude — exactly the official anthropic SDK API
claude = Anthropic()                      # wallet auto-loaded from ~/.blockrun/.session
r = claude.messages.create(
    model="claude-sonnet-4.6",
    max_tokens=2048,
    thinking={"type": "enabled", "budget_tokens": 1024},
    messages=[{"role": "user", "content": "What is 23*47?"}],
)
for block in r.content:
    if block.type == "thinking":
        print("signature:", block.signature)   # real Anthropic signature

# GPT — exactly the official openai SDK API
gpt = OpenAI()
r = gpt.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "hi"}],
)
print(r.system_fingerprint, r.model)        # genuine OpenAI direct

Async: from blockrun_llm_vip import AsyncAnthropic, AsyncOpenAI.

Wallet

The private key is used only for local EIP-712 signing and never leaves your machine. Resolution: private_key= arg → BLOCKRUN_WALLET_KEY env → BASE_CHAIN_WALLET_KEY env → ~/.blockrun/.session.

Access

Give BlockRun your wallet address to enable VIP, then pay per call from that wallet.
