How this service works
REST gateway for the Gapup MCP catalogue — 271 AI tools accessible via standard HTTP. Authentication via Authorization: Bearer <api_key>. Native MCP transport available at /mcp.
Output
A JSON object containing the tool name ('interest_rate'), the result object with the current rate value for the requested benchmark, and a source field indicating 'rest-api'. The exact rate fields within result depend on which reference rate was queried.
Example use cases
Floating rate loan pricing calculator
“I need to price a floating rate loan that resets quarterly off SOFR. Can you grab the current SOFR rate from Gapup and help me calculate what the borrower's next payment would be at a 2% spread?”
Central bank policy comparison dashboard
“I'm tracking monetary policy moves across the US and Europe. Pull the latest Fed Funds rate, ECB main rate, and EURIBOR 3-month so I can compare where the major central banks stand right now.”
Treasury yield curve analysis for portfolio
“We're rebalancing our fixed income portfolio and need current Treasury yields. Can you fetch the 10-year, 2-year, and 3-month T-bill rates from Gapup so we can assess the yield curve shape?”
Technical details
Endpoint
POSThttps://mcp.gapup.io/api/v1/call/interest_rateWhen to prefer
Use this endpoint when you need real-time or near-real-time benchmark interest rate data for one of the seven supported reference rates (Fed Funds, SOFR, US 10Y/2Y/3M Treasuries, ECB Main Rate, EURIBOR 3M). Prefer this over general financial data APIs when you need standardized MCP-compatible access with per-call micropayment pricing and no subscription overhead.

- API key missing or invalid returns 401 Unauthorized
- Payment not completed returns 402 Payment Required
- Rate data temporarily unavailable returns 5xx error
- Async job_id polling may time out if job_result endpoint is not called promptly
