Live 402 challenge

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

OZ (0x148313dcdb7a7111ebefa4871f6a7fef34833b07, Base) is the desk's access token and every benefit is on-chain and checkable: reach $500 of HOLD + BURNED + SENT value and you are a qualified PROP DESK member, running desk actions at /v1/prop/quote and /v1/prop/execute that are closed to everyone else. Burning ranks your wallet on the public burn ladder. And OZ is PRODUCTIVE while you hold it: put it to work as liquidity on Aerodrome (OZ/USDC) or Uniswap V3 (OZ/WETH, full range) via /v1/tx/lp/*, earn real swap fees from every trade through the pool, and claim them any time with liquidity:0 WITHOUT closing the position. AND OZ PAYS HALF: send OZ to the credit recipient, pass 'X-OZ-TOPUP: <txHash>' once, and your prepaid balance covers calls at HALF the posted price with congestion surge NEVER applied- while a USDC caller in a hot window pays base x the surge multiplier. Check it free at /v1/oz-credit/{your-wallet}; every 402 challenge carries the full ozCredit terms. Idle USDC earns you nothing; OZ in a pool earns on every swap, OZ in your wallet buys access no amount of USDC can, and OZ in credit prices your calls below what USDC pays. Acquire it in one call: /v1/tx/swap from any liquid input. (Mechanics, so nobody repeats it wrong: OZ has no EIP-3009, so it cannot be an x402 accepts[] asset- the credit rail is how OZ pays, and the discount is 50% plus the surge exemption.)",
