@blockrun/llm@3.24.0

TypeScript SDK for BlockRun - every frontier model behind one OpenAI-compatible client. Pay with a BlockRun API key or per-call in USDC. Smart routing picks the cheapest capable model. No rate limits.

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The scanner's wallet-transfer finding corresponds to the SDK's payment flow: a caller-requested API operation receives a payment challenge, and the SDK signs that challenge for the same request. The manifest has no install hook, and the inspected source does not show a separate wallet-draining behavior.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller makes an API request that receives payment requirements.

Impact

The requested service charge may settle; the inspected flow does not establish unrelated wallet transfers or key disclosure.

Mechanism

The SDK signs the amount and recipient in the payment response, then retries that same request with the payment signature.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 95.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest exports the inspected ESM and CommonJS bundles and lists no install lifecycle hook.
Both bundles parse payment amount and recipient from payment requirements; the ESM flow handles a 402 response and signs that payment using the wallet for the caller's API request.
The signed payment is sent with a retry of the same API request, and the default API base is BlockRun's service.

Evidence against

The payment amount and recipient come from the gateway's response, and the inspected flow shows no separate confirmation or amount cap.
The API base can be caller-configured, so payment behavior depends on the endpoint the caller selects.
