How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the query tier ('basic'), the echoed query string, and an array of search results each with a link (URL), title, and snippet (short text excerpt from the page).
Example use cases
Live news lookup for agent briefing
“Search the web for the latest news about the EU AI Act and give me the top results with links and summaries.”
Research support for report writing
“I'm writing a report on renewable energy trends — can you search the web for the most relevant recent articles and pull back titles, links, and snippets?”
Competitor monitoring in agentic workflow
“Search the web for 'OpenAI GPT-5 announcement' and return the top results so I can track what's being published about it.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/search/basic?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cheap, pay-per-call web search results inside an autonomous agent pipeline, especially when operating on Base with x402 micropayments. Ideal for agents that need occasional web lookups without a subscription, or when cost-per-query needs to be tightly controlled at $0.008 USDC. Prefer over subscription-based search APIs when call volume is unpredictable or low.
Side effects
- Query string empty or exceeds 500 characters — likely 400 validation error
- Payment not attached or insufficient — 402 Payment Required response
- Upstream search index temporarily unavailable — 500 or timeout
- No results found for highly obscure queries — empty results array returned
