ONE Engine Query Parse
x402
ONE Engine Query Parse is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Parses a natural language or structured query string into its component parts (key-value pairs and arrays) for downstream processing by autonomous agents.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing parsed query components as key-value pairs and arrays — for example, extracted attributes, filters, terms, and named entities derived from the input query string.
Example use cases
E-commerce search intent extraction
“Take this product search query — 'wireless noise-cancelling headphones under $200 for travel' — and break it down into its structured parts so I know what filters to apply.”
Agent query routing pre-processing
“Before I route this user request to the right tool, can you parse 'cheapest flights from NYC to London in July round trip' into its structured fields?”
Natural language filter decomposition
“I need you to parse 'red medium-sized winter jackets for women on sale' into labeled key-value pairs so I can pass them to our product catalog API.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/query/parse?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to decompose a raw user query string into structured key-value components at very low cost ($0.001 USDC per call) and high speed. It is ideal for agent pipelines that need to route, filter, or parameterize downstream API calls based on user intent expressed as free text. Prefer this over in-context LLM parsing when you want a deterministic, cheap, pay-per-call utility without burning LLM tokens.
Side effects
- Empty or missing query field returns an error or empty parse result
- Highly ambiguous queries may produce malformed or incomplete key-value decomposition
- Non-English or heavily idiomatic queries may parse incorrectly
- Payment failure via x402 returns 402 status before any parsing occurs
- Very long or complex queries may exceed processing limits
