How this service works
Live web search results. $0.01 USDC per call on Base, no API key. GET ?q=... (required), count 1-20 (default 10), optional country, language, page. Returns results[{ title, url, description, score }], plus Google's answer box, knowledge graph, people-also-ask, related searches and shopping when the Google-backed provider answers (empty on fallback).
Output
A ranked list of search result objects each containing a title, URL, and description snippet, plus a field indicating which search provider (Serper, Brave, or DuckDuckGo) served the results.
Example use cases
Real-time news research for agents
“Search the web for the latest news about OpenAI's new model releases and give me the top results including titles, URLs, and descriptions.”
Competitive intelligence gathering
“Find web pages about Stripe's new pricing changes — I need the top search results with titles, URLs, and summaries so I can compare what's being reported.”
Technical documentation lookup
“Search the web for 'how to set up pgvector in PostgreSQL' and return the top results with their URLs and descriptions, along with which search engine found them.”

Endpoint
POSThttps://uxus.finance/api/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need web search results that include provider attribution (Serper, Brave, or DuckDuckGo), or when you want a pay-per-use search with no subscription required. Useful for agents that need to dynamically retrieve current web information without managing API keys for multiple search providers separately.
Side effects
- Query string missing or empty — returns error
- Payment not processed — 402 response blocking access
- All three search providers unavailable — service error
- Query too long or malformed — parsing error
- Rate limit exceeded — throttling response
