Overview

AI-generated overview

A remote MCP endpoint that returns indicative fiat and crypto exchange rates, billed per request through x402 micropayments.

What it does
Rate Hub is a remote streamable HTTP MCP server that provides indicative fiat and crypto exchange rates. According to the registry description, each request is paid for through x402 at a rate of $0.0001 per request. The manifest lists no tools, so the exact tool names and parameters are not documented here. Listing tools does not require authentication; calling a tool without a credential returns the x402 payment offer instead of a result.
When to use it
Use it when an assistant needs quick indicative fiat or crypto exchange-rate lookups and you are comfortable with a per-request micropayment model. It is less suitable if you need free, unmetered access, guaranteed authoritative rates, or documented tool schemas before installing.
Requirements
A remote MCP client that supports streamable HTTP, pointed at the provider's endpoint. Network access is required. No local runtime or package is needed. Calling tools requires an Authorization header: a Bearer token beginning rh402_ or a credit token returned once by the first x402 payment. Listing tools does not require it.
Before you install
Tool calls are paid: the registry description states $0.0001 per request via x402, so usage spends money and costs should be monitored. The Authorization header carries a secret token; the credit token is returned only once by the first x402 payment, so store it safely and do not share it. The manifest declares no authentication for listing tools, and no tool list is published, so verify behavior before relying on it.
