}That's it. Every API in the apitree catalog follows the same pattern — one token, one endpoint format, standardized responses.
# Python
import requests
r = requests.get("https://apitree.ai/api/v1/proxy/exchange-rates",
headers={"Authorization": "Bearer nxs_live_YOUR_KEY"})
print(r.json()["data"]["rates"]["EUR"])
# Go
req, _ := http.NewRequest("GET", "https://apitree.ai/api/v1/proxy/exchange-rates", nil)
req.Header.Set("Authorization", "Bearer nxs_live_YOUR_KEY")
resp, _ := http.DefaultClient.Do(req)
# JavaScript
const res = await fetch("https://apitree.ai/api/v1/proxy/exchange-rates", {
headers: { Authorization: "Bearer nxs_live_YOUR_KEY" }
});
const { data } = await res.json();For AI Agent integration, install the apitree MCP Server — your agent discovers and calls APIs automatically.
