Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (19)

cancel_cartCancel an active shopping cart session by cart_id. Example: cancel_cart(cart_id='cart_1')
cancel_checkoutCancel an uncommitted checkout session by checkout_id. Example: cancel_checkout(checkout_id='chk_1')
complete_checkoutFinalize checkout settlement via Base USDC x402 or Stripe MPP. Example: complete_checkout(checkout_id='chk_1')
create_cartCreate a new shopping cart with initial line items. Example: create_cart(line_items=['agd-pass-2000'])
create_checkoutCreate a UCP checkout session for API passes or credits. Example: create_checkout(line_items=['agd-pass-2000'])
execute_marketplace_toolread-onlyExecute 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')
execute_workflow_bundleread-onlyExecute 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')
get_agent_wallet_statusread-onlyInspect 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')
get_cartread-onlyRetrieve current shopping cart items and totals by cart_id. Example: get_cart(cart_id='cart_1')
get_checkoutread-onlyRetrieve checkout session status and totals by checkout_id. Example: get_checkout(checkout_id='chk_1')
get_orderread-onlyRetrieve fulfilled order receipt and API pass key by order_id. Example: get_order(order_id='ord_1')
get_productread-onlyRetrieve full product or API pass metadata by product_id. Example: get_product(product_id='agd-pass-2000')
get_product_detailsread-onlyRetrieve product pricing and variant IDs by product_id. Example: get_product_details(product_id='agd-pass-2000')
lookup_catalogread-onlyBatch lookup catalog items by product identifier list. Example: lookup_catalog(ids=['agd-pass-2000'])
search_catalogread-onlySearch the UCP product and API credit catalog by keyword. Example: search_catalog(query='pass')
search_shop_policies_and_faqsread-onlySearch store privacy, refund, terms of service, and SLA policies. Example: search_shop_policies_and_faqs(query='refund')
search_x402_mcp_marketplaceread-onlySearch 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')
update_cartUpdate line item quantities in an active shopping cart. Example: update_cart(cart_id='cart_1', line_items=[])
update_checkoutUpdate buyer or payment rail details on a checkout session. Example: update_checkout(checkout_id='chk_1')
