Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
Over the last week it answered 98.3% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This one needs environment variables set before it will start:
AIFINPAY_AGENT_SECRET (Base58 Ed25519 secret (persistent agent identity; Solana + EVM addresses both derive from it)), AIFINPAY_MAX_USD (Hard cap per paid call (agent_call + payable_fetch), default 0.10), AIFINPAY_BASE_URL (Override the AiFinPay backend endpoint, default https://aifinpay.io).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.
