Reverse marketplace: post what you want, search wanted ads, and message sellers privately.
Scored across 13 tools
Each tool targets a distinct resource and action (wants, responses, alerts, categories, search/new feeds). The only near-pairs (get_responses vs my_responses; search_wants vs whats_new) are clearly differentiated by perspective and time in descriptions. No two tools appear to do the same thing.
Most names follow a verb_noun pattern (close_want, delete_alert, list_alerts, post_want, etc.), which is predictable. However, my_responses, my_wants (possessive noun phrases) and whats_new break the verb_noun pattern, creating minor inconsistency.
13 tools is well-scoped for a wanted-ads marketplace, covering buyer and seller flows, alerts, and categories without excess. Each tool has a clear place in the set.
Core lifecycle is covered: post/close/list own wants, search/list new wants, respond/reply, manage responses, alerts, categories. Minor gaps exist: no explicit renew_want despite the description mentioning renewal, and no update_want/edit operation, but agents can work around by closing and reposting.
Close one of the user's own wanted ads so sellers stop responding. Set found=true if the user found the item (marks it fulfilled), otherwise it is simply closed.
Inputs: id (required), found.
Delete one of the user's want alerts so they stop receiving emails for it. Get the id from list_alerts.
Inputs: id (required).
Read the responses sellers have sent to one of the user's own wanted ads: seller name, message, contact details, asking price, photo, and the private message thread with each seller (with an unread count). Only works for the user's own ads.
Inputs: id (required).
List the user's saved want alerts (keywords and/or category), with ids for delete_alert.
Inputs: no named parameters.
List the categories a wanted ad can be filed under, grouped (for example "Autos" contains "Boats" and "Cars & Trucks"). Use the category names exactly as given with post_want, search_wants, set_alert and whats_new. The list can change, so check it rather than assuming.
Inputs: no named parameters.
List the responses the user has SENT to other people's wanted ads (as a seller), newest first, each with the ad, the private message thread with the buyer, and an unread count. Use this to check whether a buyer has replied.
Inputs: no named parameters.
List the authenticated user's own wanted ads (any status), newest first. Use this to find an ad's id before closing it.
Inputs: no named parameters.
Post a wanted ad on NeedToFind: something the user is looking for. Sellers can respond by email. The ad stays live for 30 days unless renewed or closed.
Inputs: title (required), category (required), description (required), location, +1 more.
Send a private message in the conversation on a response. Works for the buyer (replying to a seller) and the seller (replying to the buyer). The other person is emailed, so only send what the user has asked you to say. Get the response_id from get_responses or my_responses.
Inputs: body (required), response_id (required).
Respond to someone else's open wanted ad on the user's behalf, saying they have the item. The buyer is emailed the message and the contact details, so only use this when the user actually has (or can get) the item and has asked to respond. One response per ad; limited to 20 per day.
Inputs: id (required), contact (required), message (required), asking_price.
Search open wanted ads on NeedToFind. Useful for checking whether someone already posted a similar want, or for finding wants a user could fulfil.
Inputs: limit, query, category.
Create an alert so the user is emailed when someone posts a wanted ad matching their keywords and/or category (for sellers who want to hear about demand for what they have). Every keyword must appear in the ad's title or description. Needs at least keywords or a category. Up to 10 alerts per user. Only affects ads posted after the alert is created.
Inputs: category, keywords.
List open wanted ads posted since a given time, newest first. Use it to notice new demand without re-running a search: remember next_since from the last call and pass it back as since. Defaults to the last 24 hours; looks back at most 30 days. Optionally limit to one category.
Inputs: limit, since, category.
