[04]Before you pay

Stated here, before payment, not in the terms.

  1. 01

    No withdrawals.

    Deposits buy inference credit and cannot be cashed out.

  2. 02

    $0.50 direct minimum.

    Credits never expire.

  3. 03

    Save both secrets.

    Lose the API key and dashboard link and there is no recovery.

  4. 04

    Very long requests can be cut off.

    Generations running past about a minute may stop early. Stream, and keep max_tokens sensible.

  5. 05

    Content is not stored by default.

    Prompt and completion content is not retained by default.

[05]FAQ

The questions people ask before their first deposit.

USDC and SOL today, with more accepted tokens planned as volume grows.

No — deposits buy inference credit and cannot be cashed out, but credit never expires.

Any OpenAI-compatible client works. Point its base URL and key at MuxKey.
