They are for your own bots and scripts, not for third-party platforms acting on your behalf. A key can spend your balance on predictions. It cannot deposit, withdraw, or rotate itself. ## Generating a key Creating a key requires a signed-in session and a prior deposit, and must be done in the web app. There is no API-only bootstrap. 1. Sign in at [soulhunt.ai](https://soulhunt.ai) with Privy. 2. Deposit USDC (card, on-chain, or Privy fund-wallet; any amount). With no deposit history and a zero balance, key generation fails with `403 deposit_required`. 3. Open your profile and generate an API key. 4. **Copy the key immediately.** It is shown once and never stored in plaintext; the server keeps only a SHA-256 hash. ### Key format ``` player_<64-hex-characters> ``` Send it as a bearer token: ``` Authorization: Bearer player_ ``` ### One key per player Each player has at most one active key. Generating a new key revokes the previous one immediately, so you can't run two keys in parallel. If you lose a key, generate a new one and update your scripts. ## Revoking a key Revoke from the profile UI, or call this endpoint while signed in with Privy: ```bash DELETE /v1/players/me/api-key ``` A revoked key is rejected with `401 invalid_api_key`. ## Brute-force protection Repeated invalid key attempts trigger a tiered lockout (up to 24 hours). Treat your key like a password: don't commit it to git or paste it into shared notebooks, and rotate it if you suspect exposure. ## Limits An API key plays the game; moving money needs a Privy session: | Operation | Available via API key | | ----------------------------------------- | --------------------------- | | Submit predictions | Yes | | View own predictions, score, claim status | Yes | | Capture a soul | Yes | | Generate or revoke an API key | **No** (Privy session only) | | Deposit, withdraw, view balance | **No** (Privy session only) | | Strategist chat, signal feeds | **No** (web/Telegram only) | A script can spend your existing balance on predictions but cannot top up your account, withdraw funds, or rotate its own credentials. Moving money requires signing in to the web app. [Predictions API](/soul-hunt/predictions-api) lists the endpoints that accept the key. > Generate, use, and revoke player API keys.
