GPTZZZ - Multi-model AI API gateway with pay-as-you-go billing
Launched on Oct 21, 2026An independent AI API gateway for developers, with OpenAI-compatible and Claude Messages endpoints, shared prepaid balance and Chinese documentation.




GPTZZZ overview
GPTZZZ is an independent third-party AI API gateway for developers. It offers OpenAI-compatible endpoints and a Claude Messages endpoint, with one account, a shared prepaid balance and usage-based billing. It is not affiliated with OpenAI, Anthropic or other model vendors.
Developers can configure compatible clients with the GPTZZZ base URL and create API keys for the model groups they need. Each API key belongs to one group; the account balance is shared across groups. The public pricing page lists models, billing groups and usage prices, while the console is the reference for current availability and charges.
GPTZZZ publishes Chinese documentation, integration guides, API error references and a public service-status page. It is aimed at developers connecting AI models to applications and coding workflows, rather than purchasing ChatGPT memberships.
Billing is prepaid and pay-as-you-go. The published rules allow Alipay top-ups of CNY 10–2,000 per transaction with no top-up fee, and applications for refunds of unused balance. Top-up amounts are deposits, not fixed monthly subscription prices.

SubmitMyStartup
SubmitMyStartup is a tool for founders who need to know where to submit their startup. Add its MCP server to Claude or ChatGPT and ask where to launch your startup, use the planner for a shortlist, or read the JSON API. Behind them is a free list of startup directories, launch directories, SaaS directories and Product Hunt alternatives, with real submission results: whether each is really free, the catch, the fees and the wait. Read-only, no sign-in.
