## What is HardysAPI?

HardysAPI is a production-grade AI API gateway launched in 2026. It aggregates multiple upstream providers (STJAPI, RelayBases, Claude Agent, native upstreams) and exposes them through one OpenAI-compatible `/v1/chat/completions` endpoint. Users pay with USD-denominated balance (1 USD ≈ 6.8 CNY) via Alipay, and can spend that balance across 26 active pricing tiers from $0.065/M tokens (GPT low tier) to $7.56/M tokens (GPT native pass-through).

The platform targets:
- Individual developers in China needing reliable access to Claude / GPT / Gemini without VPN
- AI tool authors building on top of Claude Opus 4.8 or GPT-5
- Enterprise customers needing invoicing (VAT 1%) and SLA guarantees
