Scored across 4 tools
Each tool has a distinct role: search discovers, the two execute_ tools run a single tool vs. a bundle, and wallet reports account state. The only mild overlap is between execute_marketplace_tool and execute_workflow_bundle (both 'execute'), but explicit WHEN TO USE / WHEN NOT TO USE guidance cleanly separates them.
All four tools follow a consistent snake_case verb_noun convention (search_…, execute_…, get_…). While name lengths and embedded terms vary, the underlying verb-first pattern is uniform throughout.
A gateway proxying 490+ external tools is well served by a thin 4-tool surface (discovery, single execution, bundle execution, account status). Each tool clearly earns its place with no redundancy.
Core lifecycle—discover, execute, execute-composite, check balance—is covered, and payment is handled inline via returned quotes/links. Minor gaps exist: no dedicated payment-submission/status tool and no way to browse or list available bundle_ids without prior discovery.
Available Tools
4 toolsexecute_marketplace_toolARead-onlyIdempotentInspect
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')
Inputs: input_value (required), target_tool (required), tx_hash, agent_id. Returns: data, status, roi_proof
execute_workflow_bundleARead-onlyIdempotentInspect
Execute a 4-tool native workflow bundle in parallel in a single call ($0.015-$0.03) and return a unified dossier, saving 3 LLM round-trips. WHEN TO USE: Call for comprehensive multi-source due diligence on a token, company domain, repository, or research topic; use execute_marketplace_tool when you only need a single tool. WHEN NOT TO USE: Do not use for single-endpoint queries or free catalog search. PARAMETER INTERACTIONS: Select bundle_id first and provide the matching entity identifier (token/0x address, domain, repo, or URL) in target. 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_workflow_bundle(bundle_id='example')
Inputs: bundle_id (required), target, tx_hash, agent_id. Returns: data, status, roi_proof
get_agent_wallet_statusARead-onlyIdempotentInspect
Inspect an agent's account ledger: remaining free trial calls (out of 5), prepaid USD balance, cumulative spend, total API calls, and total LLM tokens saved. WHEN TO USE: Call before a batch of paid tool executions or after completing a Stripe or USDC top-up to confirm your balance. WHEN NOT TO USE: Do not use to process web content, execute marketplace tools, or submit payments; use the other tools on this server for execution. PARAMETER INTERACTIONS: Omit agent_id to inspect the default trial account derived from your client IP, or pass your explicit agent_id or agd_pass_ session key to check a specific funded wallet. Free and read-only: never charges a fee or consumes a free trial call. Example: get_agent_wallet_status(agent_id='example')
Inputs: agent_id. Returns: data, status, roi_proof
search_x402_mcp_marketplaceARead-onlyIdempotentInspect
Search 490+ indexed MCP and HTTP 402 (x402) tools by capability keyword and return ranked endpoints with pricing, trust scores, and SLA tiers. WHEN TO USE: Call first to discover which native slug or external endpoint matches your task before calling execute_marketplace_tool. WHEN NOT TO USE: Do not use to execute a tool directly (use execute_marketplace_tool or execute_workflow_bundle). PARAMETER INTERACTIONS: Pass capability keywords or a domain in query; omit agent_id and tx_hash (this discovery tool is always free and never consumes a free trial call). Example: search_x402_mcp_marketplace(query='example')
Inputs: query (required), tx_hash, agent_id. Returns: data, status, roi_proof
