Platinum Price Grounding Data

Overview

The API polls live precious metal markets and delivers spot rates across troy ounces, grams, and kilograms. By default, responses return quotes in USD with 24-hour price change amounts and directional trends. Upgrading to a paid plan lets you convert prices into 172 world currencies, view 24-hour high and low ranges, or pull 24 hours of hourly price snapshots. Use it for today's platinum price per troy ounce (oz), per gram or per kilogram. The last 30 daily closes are stored too: paid plans get the 7- and 30-day change and the 30-day high, low, average and volatility, and daily=true returns the closes themselves.

The tool

Once your client is connected to the VerveContext server, this appears in its tool list as PlatinumPriceGroundingData. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

{
  "name": "PlatinumPriceGroundingData",
  "arguments": {}
}

Connecting

One server URL covers every source in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervecontext": {
      "url": "https://api.vervecontext.com/v1/mcp"
    }
  }
}

https://api.vervecontext.com/v1/mcp

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Why ground on it

A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong. This source returns the current value in a shape you can check, which is the difference between an answer you can cite and one you have to hedge.

Point an evaluation at gram: it is the field most worth pinning a claim to, and it is either present and current or absent — never plausibly invented.

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.

Supported Currencies

170+ world currencies supported including fiat currencies, cryptocurrencies, and precious metals.

Use cases

Jewelry Inventory Valuation

When revaluing finished jewelry stock, retail catalog systems calculate replacement costs based on spot platinum prices per gram.

Bullion Checkout Rates

Bullion dealers lock in customer checkout totals by converting ounce rates into local purchase prices right before payment capture.

Scrap Metal Intake

Price scrap catalytic converters accurately by referencing live per-kilogram platinum values and day-over-day change directions during intake.

Commodities Portfolio Tracking

To monitor precious metal allocations, wealth management dashboards track spot rates and 24-hour price shifts to calculate daily asset swings.
