Authentication

Every API call carries your chainz sign-in token as a bearer token. How to get it and renew it.

Every call carries your sign-in token in the Authorization header:

http

Authorization: Bearer <token>

Get your token

While signed in to chainz in your browser, open:

text

https://app.chainz.waiyers.com/api/auth/token

The answer is JSON; the token is the idToken field. From a script, send your session cookie:

bash

TOKEN=$(curl -s https://app.chainz.waiyers.com/api/auth/token \
  --cookie "next-auth.session-token=$SESSION" | jq -r .idToken)

$SESSION is the value of the next-auth.session-token cookie of app.chainz.waiyers.com (your browser's developer tools › Application › Cookies).

Warning

The token acts as you: anyone who has it can run your flows and spend your credits. Keep it out of code repositories and shared documents.

The token expires like your session. When a call returns 401, get a new one.

Settings › API Keys can create keys, but they do not run flows yet. Use the token above until they do; this page will say when.

/api/auth/token only answers pages of app.chainz.waiyers.com itself: a script on another website cannot read your token.
