What it does

What is China talking about right now — three hot lists in one call: Baidu (百度热搜), Weibo (微博热搜) and Toutiao (头条热榜). Merges them into one view and adds a CROSS-SOURCE signal: topics that appear on 2+ platforms are ranked first, because those travel across communities instead of spiking in a single one. Returns crossSource (with the rank each platform gave it) and bySource. Optional ?perSource=5-30. No single Chinese platform exposes this merged view — each one only shows its own list. 中文：全网热搜聚合（百度+微博+头条），并标注哪些话题同时上了多个榜。 No API key and no signup: call the endpoint, it answers HTTP 402 with the payment terms, pay per request in USDC on Base with any x402-compatible client or wallet, then retry the same request to get the data.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/74974.json for the price and payment options.
3. Pay. Call GET https://cn-data-x402.cn-data-x402-worker.workers.dev/cn/hot-all. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
