Agent Data Hub

Routes a plain-language data question to the best matching live endpoint, runs it and returns the data as compact JSON with source, license and data_freshness. Use first when you do not know which endpoint fits, e.g. "convert 250 usd to eur", "weather berlin tomorrow", "germany inflation", "bitcoin price". If nothing matches it returns status "unfulfilled" — then use search_apis. Read-only, no API key or signup. Free quota: 1000 calls/day per IP, shared across tools.

  },

    "query"
  ]
}

Searches the catalog of 600+ endpoints (FX, macro, weather, energy, geo, research, developer tools, space) by keyword and returns up to 50 matches with id, description and an example query. Use to pick an apiId for call_api. Does not fetch any data and does not count against the quota.

Runs one endpoint by id with parameters and returns its data as compact JSON (source, license, data_freshness included). Bundles answer whole tasks in one call: bundle-location-brief (weather, time, holidays for a place), bundle-country-brief, bundle-eurozone-brief, bundle-energy-brief-de, bundle-npm-package-brief. Get ids from search_apis. Unknown ids or bad params return an error message. Read-only, no API key or signup. Free quota: 1000 calls/day per IP, shared across tools.

Returns complete numeric histories as compact CSV (t,value) from an archive of 14,000+ openly licensed series: ECB FX rates since 1999 (fx.EUR.USD), 58 World Bank indicators for all countries since 1960 (wb.FP.CPI.TOTL.ZG.DE), Eurostat (eurostat.une_rt_m.DE), ECB rates and 10y yields (ecb.rate.deposit, ecb.yield10y.IT), German power prices and generation (smard.price.day), sunspots since 1749 (noaa.sunspot-number). Pass q to search series ids, or id to fetch one (max 1,000 points, most recent kept). Read-only, no API key or signup. Free quota: 1000 calls/day per IP, shared across tools.

Returns change points this service recorded over time for an endpoint (e.g. exchange rates, weather) as compact CSV. Use the same params as the live call. For long official histories prefer get_series. Returns an error if nothing was recorded for these params. Read-only, no API key or signup. Free quota: 1000 calls/day per IP, shared across tools.
