• execute_marketplace_tool

  Execute any of the 16 native AgentDiet B2A tools by slug or proxy an external marketplace tool URL ($0.001-$0.02 per call). WHEN TO USE: Call to run a single tool discovered via search_x402_mcp_marketplace; use execute_workflow_bundle when you want to run a 4-tool composite bundle in parallel. WHEN NOT TO USE: Do not use for catalog search (use search_x402_mcp_marketplace) or wallet checks (use get_agent_wallet_status). PARAMETER INTERACTIONS: Set target_tool to a native slug (e.g. 'distill', 'token-intel', 'sec-intel', 'github-audit') or external https:// URL, and pass its primary input in input_value. Omit agent_id and tx_hash during your 5 free calls. Read-only and idempotent; results are cached for 1 hour (<5ms cache hit). Pricing: the first 5 calls per agent_id are free and failed calls are never charged. After 5 calls, the tool returns a payment-required quote (not a fatal error) with a $2 Stripe top-up link and Base/Solana USDC addresses; complete payment, then retry with your agd_pass_ key in agent_id or pass tx_hash. Example: execute_marketplace_tool(target_tool='example')
