100% compatible with the official OpenAI SDK. We handle the EIP-712 wallet signatures, atomic Redis routing, and concurrent streaming settlements under the hood. You just change the base URL. 100% 兼容官方 OpenAI SDK。我们在底层处理 EIP-712 钱包签名、Lua 原子化路由和并发流式结算。你只需修改基地址。
from openai import OpenAI client = OpenAI( # Just change the base URL base_url="", api_key="your_wallet_session_token" ) stream = client.chat.completions.create( model="claude-sonnet-4-20250514", messages=[{"role": "user", "content": "gm!"}], stream=True ) # Response headers: # X-USDT-Cost: 0.000342 # X-USDT-Balance: 0.099658
From wallet to AI response in four steps.从钱包到 AI 响应，只需四步。
Call the API like any OpenAI endpoint. Get a 402 Payment Required response.像调用 OpenAI 一样发起请求，获得 402 支付要求响应。
Your wallet signs a USDT transfer authorization. No on-chain tx needed upfront.钱包签署 USDT 转账授权。无需预先链上交易。
Signature verified in ~1ms, balance reserved, routed to the best model, response streamed.约 1ms 验证签名，预留余额，路由到最佳模型并流式返回。
Only actual token usage is charged. Unused balance refunded. Settlement on-chain async.只收取实际使用量，未用余额退还，链上异步结算。
Built for trustless environments. Every byte, every cent, secured.为无需信任的 Web3 环境构建。每一个字节，每一分钱，皆有保障。
API endpoints never touch crypto private keys. Signatures govern intent, while an isolated Settlement Worker processes the on-chain queue.API 端点绝不接触加密私钥。只有数字签名传递意图，由隔离的结算工作器安全处理链上队列。
High-performance Redis Lua scripts operating with strict linearity. Zero TOCTOU vulnerabilities, eliminating race conditions at the nanosecond level.严格线性执行的高性能 Redis Lua 脚本。全量消灭 TOCTOU 竞态漏洞，纳秒级阻绝双花风险。
Any interrupted stream triggers immediate clawback of unspent tokens. Failed settlements persist in DLQs with 5x retry, assuring absolute ledger integrity.任何中断的流式预留都会即刻触发余额回滚。罕见的清算失败将被持久化至 DLQ 并 5 次重试，绝不丢弃数据。
Provider rates + 20% markup. No hidden fees, no subscriptions.厂商费率 + 20% 加价。无隐藏费用，无订阅。
