Ethereum Price Skill

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 VerveKit server, this appears in its tool list as EthereumPriceSkill. 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.

Tool call

{
  "name": "EthereumPriceSkill",
  "arguments": {}
}

Connecting

One server URL covers every skill 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": {
    "vervekit": {
      "url": "https://api.vervekit.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.

Argument	Type	Description
`currency`OptionalPremium	string	The currency to get the price in default USD
`hourly`OptionalPremium	boolean	Include hourly price data for the past 24 hours
`hourly[].hour`Optional	number	UTC hour-of-day slot (0-23) the price was captured in
`hourly[].price`Optional	number	Price at that hour, in the requested currency
`hourly[].timestamp`Optional	string	ISO 8601 time the hourly price was captured

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.

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.

Status	What it means
`400` / `422`	The arguments did not validate. The message names the offending one.
`401`	The OAuth session is invalid or expired — reconnect the server.
`403`	Blocked by a key restriction or an IP allow-list. Never a bad identity.
`404`	This skill is not part of VerveKit. Check the catalog.
`429`	Out of credits, or a brief rate limit. The message tells them apart.

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.
