FairStash — Roblox trade values

What one item is worth in a Roblox trading game — Flee the Facility (FTF), Murder Mystery 2 (MM2) or Adopt Me. Returns the community trade value, how wanted the item is, where it stands in its own catalogue, how often it turned up in the newest marketplace listings, and the date the numbers were collected. Use it for questions like "how much is a Chroma Luger worth in MM2". Values are community estimates, not official Roblox prices.

Adds up both sides of a proposed trade in one game and answers win, fair or lose, with the gap in per cent. Both sides are written as the player would say them: "2 party balloons, sakura" or "neon shadow dragon". A trade that mixes two games is refused rather than calculated: the three games use different scales that cannot be added together.

      "type": "string",
      "description": "What the player gives away, comma separated. Russian works, including quantities and pet variants: \"неон теневой дракон\", \"2 ледокол 2020 и хрома люгер\"."
    },
    "get": {
      "type": "string",
      "description": "What the player receives, comma separated. Russian works here too: \"ледяной дракон\"."

The most valuable items in one game, most valuable first, with their community values and page links. Optionally narrowed to one section of the catalogue (for MM2: godly, ancient, sets, pets, chroma, knife, gun…). Use it for "what are the most expensive knives in MM2" or to see what a game's scale looks like.

Finds items across all three games by a partial name and returns the candidates with their game, value and page link. Use it when the name a player wrote is ambiguous, misspelled or could belong to more than one game, before asking get_value for the exact one.

  "properties": {
    "query": {
      "type": "string",
      "description": "Part of an item name, e.g. \"chroma\", \"dragon\", \"hammer\" — or in Russian: \"дракон\", \"нож\"."
    },
    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 25,
      "description": "How many candidates. Default 10."
    }
