Common questions

Is Arbitron safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Arbitron API and MCP server

Read-only market data for crypto perpetual futures across the venues Arbitron tracks: current funding rates, funding history, the spread between two venues right now, the scanner's backtested spreads, and the listings calendar. Two doors to the same data: a REST API for programs and an MCP server for AI assistants.

This repository holds the public artefacts of that product so they can be pinned, diffed and cited. The service itself is closed source.

Every response is { "data": ..., "meta": { "as_of", "delayed_seconds", "source", "url", "count", "total", "next_cursor" } }. Errors are RFC 9457 problem details. Rates are percent per settlement. More in examples/.

MCP in one minute

Claude Desktop, Cursor and ChatGPT connect with OAuth 2.1 (sign in with your Arbitron account); a program connects with the same API key as a bearer token. Client configurations are in mcp/clients/. Nine read-only tools: arbitron_search_coins, arbitron_get_funding_rates, arbitron_get_coin_funding, arbitron_get_funding_history, arbitron_get_spreads, arbitron_get_spread_backtest, arbitron_get_listings, arbitron_get_exchanges, arbitron_get_usage.

Plans

The Demo plan is free: 15-minute delayed data, 50 rows per page, no history. Paid plans (Developer, Pro, Business) are live, reach further back, and include commercial use. Details at https://arbitron.app/developers#plans.

Citing

Attribute republished figures as "Data: Arbitron" with a link to meta.url, and keep meta.as_of with the number. Name the exchange and the settlement interval beside any funding rate.
