• nexbid_purchase

  discovery

  <tool_description> Initiate a purchase for a product found via nexbid_search. Returns a checkout link that the user can click to complete the purchase at the retailer. The agent should present this link to the user for confirmation. </tool_description> <when_to_use> ONLY after user has expressed clear purchase intent for a specific product. Requires a product UUID from nexbid_search or nexbid_product. ALWAYS confirm with user before calling this tool. </when_to_use> <combination_hints> nexbid_search (purchase intent) → nexbid_purchase → present checkout link to user. After purchase → nexbid_order_status to check if completed. Use checkout_mode=wallet_pay when the user has a connected wallet with active mandate. </combination_hints> <output_format> For prefill_link (default): Checkout URL that the user clicks to complete purchase at the retailer. For wallet_pay: Intent ID and status for mandate-based authorization. Include product name and price for user confirmation. </output_format>

• purchase_book

  bookstore4agents

  Complete a paid purchase of a book. This is a TERMINAL ACTION: it creates an order, charges the buyer, and grants a permanent entitlement. Only call this when the user has EXPLICITLY requested to buy. Never call as part of browsing, price comparison, or information gathering — prices are already visible in search_books results, and free previews are available via get_book_preview. If the user says 'don't buy', 'just compare', 'just tell me the price', or similar — do NOT call this tool. If the user requests an action that requires owning a book they don't own (e.g. commenting on an unowned book), do NOT silently purchase it on their behalf. Instead, tell the user the purchase requirement and ask them to confirm. Spending money is never an inferred default.

• dispatch_social_listening_researcher_async

  Heista

  Dispatch to the SOCIAL LISTENING RESEARCHER — multi-platform community-signal interpretation. Use for: "what are practitioners saying about X across platforms / what jargon is emerging in field Y / what is the cross-platform discourse around brand/topic Z". Treats T3 community sources as primary data, distinguishes cross-platform patterns from single-platform noise. ≥3 platforms sampled per brief. Returns: Signal map (Signal / Platforms / Volume / Sentiment + recency) + Per-platform evidence trail + Cross-platform vs single-platform classification + Confidence flag + Sources. NOT for: single-source thematic work (use dispatch_qualitative_researcher) / numerical sentiment effect sizes (use dispatch_quantitative_researcher). ASYNC version: returns { job_id } immediately, the specialist runs durably on a Vercel Workflow (no 300s timeout). Use this version when the specialist is expected to take >90s. Call get_dispatch_result(job_id) periodically (respect wait_ms_hint in the response) until status === 'completed' or 'failed'. Idempotent: same brief + same org reuses the same job_id, so retries don't fan out duplicate runs.

• get_practice_radar_offer

  ActableSite AI Crawler Monitor

  Return the current Practice Radar weekly-edition receipt, public sample, exact $19 one-time and $39 monthly options, included fields, delivery and cancellation paths, and material NPI limitations.

• marketplace_buy

  invinoveritas

  Purchase a service listing from the Lightning-native agent marketplace. Provide the listing_id; payment routes instantly via Lightning with 95% going to the seller. Use to hire other agents' services, buy data feeds, signals, or analysis. Returns purchase confirmation and the seller's delivery content. TIP: a buy is an irreversible spend on another agent's offer — set verify_before_buy=true to get a neutral /review verdict on the listing FIRST; a reject blocks the purchase with no sats spent.

• get_balance

  Unphurl

  Check your pipeline check credit balance. Shows credits remaining, total purchased, total used, and lifetime free lookups count. Credits are consumed only when unknown domains run through the full analysis pipeline. Known domains (Tranco Top 100K) and cached domains (previously analysed by any Unphurl customer) are always free. If credits_remaining is 0, you can still check known and cached domains for free. To check unknown domains, purchase more credits using the "purchase" tool.

• get_cart

  Kifly — Agentic Commerce & Payments

  Inspect the current state of a cart — line items, quantities, prices, and shipping address. Each item includes an `item_id` you can pass to `update_cart_item` to change quantity or remove the item. Call this after `add_to_cart` to review the cart before checkout, or any time the buyer asks what's in the cart. `kifly_purchasable: false` (`fulfillment: "external"`) means checkout on this cart will hand off to the seller's own site instead of charging — say so before the buyer expects a real purchase.

• explain_coverage

  Bandago Van Rentals

  Explain Bandago's optional insurance / coverage products (CDW, RLP, SLI, PAI, and THE WORKS bundle) with authoritative deductibles, dollar limits, PAI benefits, brochure links, and online availability. Reads the centralized policy source of truth, so limits and availability are state-correct. Pass a state or location to get the exact SLI limit and whether RLP/SLI can be bought online there (they are restricted in some states, e.g. FL/GA/TX). Use this instead of quoting coverage details from memory.

Use this before search_pieces when you want to build a precise query from real values rather than guesses.
