How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A pretty-printed JSON object containing search results for the submitted query value, formatted for readability and easy downstream parsing by autonomous agents.
Example use cases
Agent pipeline web search lookup
“Search for 'latest AI agent frameworks' and return the results as pretty-printed JSON so I can parse them in my pipeline.”
Cheap per-call data retrieval for bots
“I need a low-cost search call — query 'top Python libraries for data science 2024' and bring back formatted JSON results.”
Autonomous agent knowledge fetch
“My agent needs to look up 'current Base blockchain gas fees' — run that search and return the JSON output in a readable format.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/json/pretty?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need sub-cent ($0.0009 USDC) per-call search results returned as clean, pretty-printed JSON, especially in autonomous agent pipelines on Base that already support x402 micropayment flows. Prefer it over heavier search APIs when cost-efficiency and machine-readable JSON formatting are the primary requirements.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- Missing or empty 'value' field in POST body — may return empty or error response
- Malformed JSON body — returns 400 Bad Request
- Query yields no results — returns JSON with empty results array
- Network or worker timeout — returns 5xx error
