How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns a JSON object containing a 'results' array (each item has url, title, and snippet fields) and a 'synthesis' string — an LLM-generated summary that distills the top results into a coherent answer.
Example use cases
Current events research assistant
“Search for the latest developments in quantum computing breakthroughs this year and summarize what the top results are saying.”
Competitive intelligence lookup
“Search for 'top AI coding assistants 2025 comparison' and synthesize the key findings from the results you find.”
Technical documentation discovery
“Search for 'how to implement RAG with LangChain' and give me a synthesized answer with the most relevant links.”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/llm/searchWhen to prefer
Choose this endpoint when you need both raw search result links (URL, title, snippet) AND an LLM-synthesized summary in a single call, paid per-use via crypto microtransaction. Ideal for agents that need grounded, cited answers without maintaining a search API subscription.
Side effects
- Empty or vague query may return poor results or empty results array
- Payment failure via x402 protocol results in 402 response and no data
- Synthesis field may be empty if no relevant results are found
- Rate limiting or service downtime on the vercel.app backend
- Query too long or malformed JSON may result in 400 bad request
