Quick start

Call an endpoint as https://www.masterinvest.info/api.php?method=<method>&action=<action> (always available) — the clean /api/v1/<method>/<action> form is equivalent where URL rewriting is enabled.

curl

curl -s "https://www.masterinvest.info/api.php?method=coin&action=price&market=bitcoin&base=usd&type=fiat"

JavaScript

const r = await fetch("https://www.masterinvest.info/api.php?method=coin&action=price&market=bitcoin&base=usd&type=fiat");
const j = await r.json();
if (j.status === 1) console.log(j.return);

Response format

Every response is { "status": 0|1, "message"?: "...", "return"?: ... }; status:1 = success. Please cache responses and keep a sane request rate.
