API reference

REST over HTTPS with JSON bodies. Everything the web app does goes through this API.

Basics

  • Base path: /api. Requests and responses are JSON. Large on-chain integers (lamports, raw token amounts) are serialized as strings; dates are ISO 8601.
  • Auth uses the session cookie from /api/auth/verify. “Creator” endpoints require the wallet that launched the AI; “Holder” endpoints check the on-chain balance.
  • CSRF: mutating requests (POST, PUT, PATCH, DELETE) must be same-origin, or send the header x-idolpad: 1.
  • Strict validation: unknown fields in a body are rejected with 400.
  • Pagination is cursor-based: pass the nextCursor from a response as cursor; null means the end.
  • Signing: endpoints that move funds return unsigned or partially-signed transactions as txBase64. Sign with the wallet and send back signedTx. The server never holds your keys.
Examplebash
curl -s "https://higgsy.space/api/tokens?tab=trending&limit=4"

curl -s -X POST "https://higgsy.space/api/reports" \
  -H "content-type: application/json" -H "x-idolpad: 1" \
  -d '{"subjectType":"token","subjectId":"<tokenId>","reason":"real_person"}'

Errors

Every error has the same shape:

json
{
  "error": {
    "code": "policy_denied",
    "message": "Daily limit reached ($10.00 of $10.00 spent)",
    "details": { … }
  }
}
StatusCodeMeaning
400bad_request / validation_errorMalformed JSON, invalid fields or unknown fields (bodies are validated strictly).
401unauthorizedSign in with your wallet first.
402policy_deniedThe spending policy denied the action. message is the reason — not a failure, adapt and retry differently.
402payment_requiredA paid quote is required (e.g. second character generation).
403forbiddenNot your AI, admin only, or failed CSRF check.
404not_foundUnknown or delisted resource.
409conflict codese.g. locked (fee split), already_launched, ticker taken.
422moderation_blockedBlocked by moderation. details.categories lists why.
423frozenThe AI is frozen — kill switch active.
429rate_limitedToo many requests. details.retryAfter is in seconds.
500internal_errorSomething went wrong on our side.
402 is a decision, not a crash
The policy engine answers every paid action with approved, pending or denied. A denied action returns 402 policy_denied with the reason in message; a pending one returns normally with decision: "pending" and waits in the creator's approval queue.

Rate limits

Limits are fixed windows per endpoint, keyed by the signed-in user (or by IP address when signed out). Expensive and money-moving endpoints have tighter limits than reads. When you exceed a limit you get 429 rate_limited with details.retryAfter in seconds — back off for at least that long.

Auth

Sign-In With Solana: request a nonce, sign the returned message with the wallet, verify. The session is an httpOnly cookie valid for 7 days. No passwords.

POST/api/auth/noncePublic

Create a single-use sign-in nonce for a wallet.

Body
{ "wallet": "<base58 pubkey>" }
Response
{ "nonce": "…", "message": "<text to sign>" }
POST/api/auth/verifyPublic

Verify the signed message and start a session (sets the session cookie).

Body
{ "wallet": "…", "nonce": "…", "signature": "<base58>" }
Response
{ "user": { "id", "wallet", "role", "freeGenUsed" } }
POST/api/auth/logoutSigned in

End the session.

Response
{ "user": { … } | null, "unreadNotifications": 0 }

GET/api/characters/:jobIdSigned in

Poll a character job.

Response
{ "status": "queued|generating|done|failed|blocked", "outputs": { "fullBody", "headshots": [4] } }
