Ethereum Price Grounding Data

Overview

Ethereum Price works by fetching the latest market data for Ethereum from multiple reliable sources. It returns the current price, market capitalization, 24-hour trading volume, and 24-hour percentage change. The data is refreshed hourly and can be returned in any supported currency.

The tool

Once your client is connected to the VerveContext server, this appears in its tool list as EthereumPriceGroundingData. 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": "EthereumPriceGroundingData",
  "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"
    }
  }
}

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A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong.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 price: 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.

Use cases

NFT Mint Quoting

When collectors initiate an NFT purchase, minting engines pull the latest ETH rate to display fiat-equivalent costs before transaction confirmation.

DeFi Collateral Monitoring

Lending protocols evaluate borrower health against liquidation thresholds by verifying real-time price changes and movement direction across active loan positions.

Web3 Paywall Processing

Digital media paywalls compute the exact fractional ETH owed for access passes using real-time price quotes during checkout.

Smart Contract Escrow

To safeguard milestone payouts, freelance escrow platforms record the ETH price and movement direction when an agreement begins.
