​
X-Api-Key
string
header
required

Partner / integrator key — format ps_live_<keyId>_<secret>. Issued by PredictStreet ops via the admin panel; never self-service. Never ship to a browser. multi_wallet partners must additionally send X-User-Wallet: 0x<40-hex> on every authenticated request to declare the acting wallet. See the API keys guide for scope taxonomy, partner kinds, rate limits, and rotation procedure.

Headers

​
X-User-Wallet
string

Required for multi_wallet partners on every authenticated request; ignored for single_wallet. Declares the acting end-user wallet for this request — drives KYC checks, balances/positions/orders attribution, rate-limit buckets, and audit. Lower-cased server-side. Missing on a multi_wallet key → 401 api_key_user_wallet_required; malformed → 401 api_key_user_wallet_invalid. The on-chain CTFExchange/Vault contracts still verify EIP-712 signer ↔ vault binding, so loosening API-layer attribution is safe by construction.

Pattern: ^0x[a-fA-F0-9]{40}$
Example:

"0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb3"

Response

200 - application/json

OK

​
tier
integer
required

0-based tier index. 0 = base tier; higher tiers get lower fees.

Example:

0

​
makerBps
integer
required

Maker fee in basis points at this tier. Informational only — the quadratic taker-fee curve makes on-chain settlement fees depend on price, not bps. See /concepts/trading/fees.

​
takerBps
integer
required

Taker fee in basis points at this tier. Same caveat as makerBps.

​
rolling30dVolume
any
required

Taker-side USDC volume over the trailing 30 days that qualifies for tier bracketing.

​
nextTierVolume
any | null
required

USDC volume needed to reach the next tier. null if the caller is already at the top tier.
