## Pricing

from $10.00 / 1,000 client lookups

This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Precious Metals Spot Prices

Real-time precious metals spot prices for AI agents via MCP. Gold, silver, platinum, palladium, and copper — live futures data with bullion value calculator.

Built by [Mowell Labs](https://github.com/MowellLabs).

### What it does

This MCP server gives AI agents instant access to precious metals market data. No scraping, no API keys to manage — just call the tool and get structured JSON back.

- **Live spot prices** from Yahoo Finance futures (GC=F, SI=F, PL=F, PA=F, HG=F)
- **Bullion value calculator** — spot × weight × purity for any bar, round, or coin
- **US silver coin melt values** — pre-1965 dimes, quarters, half dollars, and dollars
- **60-second cache** — fast responses without hammering the data source
- **Validation** — price range checks filter bad data from contract rollovers

### Tools

#### `get_spot_price`

```json
{
  "metal": "gold",
  "weight_troy_oz": 1.0,
  "purity": 0.999,

```

Common purity values: 0.999 (fine), 0.9167 (22k gold), 0.900 (90% silver coins), 0.9995 (platinum).

#### `get_silver_melt_value`

Calculate the silver melt value of pre-1965 US coins.

**Input:**

```json
{"denomination": "quarter", "year": 1964}
```

**Output:**

```json
{
  "denomination": "quarter",
  "year": 1964,

### Use with Claude Desktop

Add to your MCP client configuration:

```json
{
  "mcpServers": {
    "spot-prices": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mowell-labs--spot-prices.apify.actor/mcp"]
    }
  }
}
```

Then ask your AI assistant:

- "What's the current gold price?"
- "How much is a 10 oz silver bar worth?"
- "What's the melt value of a 1964 quarter?"
- "Give me all precious metals prices."

### Data source

Prices are sourced from Yahoo Finance futures contracts via the `yfinance` library. These are near-month futures prices that closely track spot during market hours.

- Cache TTL: 60 seconds
- Fallback prices returned (clearly marked) if live data is unavailable
- Price validation filters bad data from contract rollovers or API glitches

## CLI example

```bash
echo '{}' |
apify call mowell_labs/spot-prices --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,mowell_labs/spot-prices"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
