Basic (≥0.03 USDC, 30000 atomic): direct 0x execution. Resilient (≥0.10 USDC, 100000 atomic): dual-lane concurrent race — 0x/ParaSwap aggregator stack vs Aerodrome on-chain read, highest buyAmount wins. Institutional (≥0.50 USDC, 500000 atomic): dual-lane race plus Uniswap V3 triple-fee-tier on-chain safety net if both lanes fail. To use: call GET /api/v1/quote with sellToken, buyToken, and sellAmount. A 402 response includes a tiers object with exact min_atomic values for each tier. Fund your EIP-3009 authorization.value to the desired tier's min_atomic, include the signed payload in the X-Payment header, and retry.
