API keys
Use an API key, your account credential, to authenticate calls.
Get and manage your key
Open Developers → Keys to create or revoke a key. Creating a key needs a saved card. Rotating or revoking a key does not. Developers → Keys shows your current key’s masked prefix; press Reveal key to view the full key again. It hides after 60 seconds or when you leave.
A missing or invalid key receives 401 invalid-key, and nothing is charged.
Your balance is the money in dollars available to spend now.
Distinguish keys from your balance
A valid API Key with an empty Balance still authenticates. The request is then refused
as 402 insufficient-credits — a different error,
with a different fix. 401 means fix the key; 402 means add funds.
POST /v1/validate needs a valid key and works at zero Balance without spending.
Rotate or revoke a key
Press Rotate key in Developers → Keys yourself; the replacement appears in full. Rotation leaves your Balance and Tier unchanged and charges nothing.
A revoked API Key can continue to authenticate for up to ~60 seconds after revocation — the gateway holds a short-lived key cache — and within a minute it stops everywhere. If you are rotating credentials on a schedule, treat that minute as part of the rotation window: issue the new key, move traffic, then revoke the old one.
If calls must stop now
Ask us to zero your Balance: contact support@investorliftdata.com.
A zero Balance refuses charged calls on the request itself, independently of key-cache propagation.
Your history stays intact, and you can add funds again afterwards. Revoke the key as well: zeroing stops spending; revocation retires the credential.
