Baidu Search API is Baidu’s search offering oriented to the Chinese market. FreeSerp is a free, keyless web search API for AI agents — a drop-in alternative you can call with no key, no signup and no per-request bill.
Point your agent at FreeSerp’s JSON endpoint or its MCP connector and it searches 20M+ live sites in real time, getting back ranked results with LLM summaries — the same shape you would wire Baidu Search API into, minus the account and the invoice.
When does Baidu Search API still win? When you specifically need China-region coverage. Reach for FreeSerp when you want free, agent-native web search without a key — for retrieval, grounding, monitoring or tool-calls where cost-per-request and signup are the real blockers.
