How this service works
The European Central Bank's Main Refinancing Operations (MRR) key policy rate level via the ECB SDMX Data Portal (keyless JSON, dataflow FM). Serves autonomous eurozone monetary-policy agents and agent-to-agent macro bots pricing EUR rate expectations off the official ECB benchmark. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
Returns a JSON object with ok status, the niche identifier 'ecb-key-policy-rate-mrr', the queried series key, a set of dated rate observations, and provenance metadata including the source ECB SDMX API URL and source label.
Example use cases
Eurozone rate expectation pricing bot
“Get me the last 5 ECB MRR policy rate observations so I can price current EUR interest rate expectations — use series key D.U2.EUR.4F.KR.MRR_FR.LEV and return jsondata format.”
Macro policy dashboard refresh
“What's the current ECB main refinancing rate? Fetch the most recent observation using the standard MRR series key so I can update our monetary policy dashboard.”
Automated rate change monitoring agent
“Check the ECB MRR key policy rate for the last 10 observations — I want to detect if there's been any recent change to the benchmark rate level.”

Endpoint
POSThttps://ecb-key-policy-rate-mrr.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need the official ECB Main Refinancing Operations benchmark rate sourced directly from the ECB SDMX Data Portal, especially for autonomous eurozone monetary-policy agents, macro bots pricing EUR rate expectations, or any workflow requiring the authoritative ECB MRR rate level with full provenance. Prefer this over scraped or aggregated rate sources when auditability and official sourcing matter.
Side effects
- ECB SDMX Data Portal upstream unavailability causing empty or failed observations
- Invalid or malformed series_key resulting in no data returned
- Unsupported format string causing parsing errors
- lastNObservations value out of acceptable range returning no results
- Network timeout from ECB API backend
