Contact & support
Ask about data, your API key or the apps. We reply within one business day — right here; a badge on your avatar shows new replies.
Sign in, open Profile and describe your project in a couple of lines with a link. The key appears right away and is free.
Base address: https://api.cryptoetf.today/api/v1/ Send the key in the header Authorization: Bearer <your key>. The full list of endpoints is in the API docs (docs.cryptoetf.today).
The key is missing, mistyped or revoked. Check that the header is exactly Authorization: Bearer <key> with no extra spaces or quotes, and copy the key again from your profile.
Our 403 means the key was suspended — the response body is JSON and says so, and you will find a message from us in Support. If the 403 comes as an HTML page, the request was stopped before it reached us: by a proxy, VPN, corporate firewall or a security service. Check the host name and try from another network.
REST: 120 requests per minute per key. MCP server: 60 requests per minute per IP. Above that you get 429 — wait a minute and retry, and cache responses on your side: data changes once or twice a day.
The last 30 days, for everyone. Longer history is available to data partners — see Data partnerships.
Flows are published one business day after trading (T+1). The daily issue goes live around 05:50 UTC, Tuesday to Saturday; a second pass around 23:10 UTC adds funds that published late.
0 means the funds reported and no money moved. A dash means not all funds of that asset have reported yet — it fills in after the next update.
Yes, free, with the credit “Data: cryptoetf.today” and a link. For a site the easiest way is the widget builder; for apps — the API.
No. Connect the MCP server by its address from the MCP page; widgets work with the embed code from the widget builder.
Profile → Delete account, or the Delete account page in the footer. Your data is removed within 30 days.
