Findings (1)
- LOWTool 'get_api_public_keys' description lacks action verbin get_api_public_keys
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~5,054Tokens (tool definitions)
~11.0 KBTypical response size
Significant attention impact (3.95% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}⚪issue_api_receipt(event, idempotencyKey)
Persist a signed commitment to a client-declared HTTP exchange. Public price: 0.002 USDC via x402 when enabled; otherwise requires pilot issuance permission. Preserve the event, idempotency key and original payment authorization on retries. This does not prove independent observation or the truth of the response.
