How this service works
Data and AI services via x402 payment protocol
Output
Returns a JSON object containing index query results matching the input string, which may include data records, AI-generated content, or structured information from the namespace index. The response schema is open-ended ({}) so the shape of returned data depends on what is stored in the index.
Example use cases
Semantic search over indexed dataset
“Query the Orders of Magnitude index for 'renewable energy adoption rates by country' and show me what comes back.”
AI data lookup for research
“Can you look up 'machine learning model benchmarks 2024' in the Orders of Magnitude namespace index?”
Retrieve structured records by keyword
“Search the Orders of Magnitude index for 'protein folding simulation results' and give me whatever records it returns.”
Technical details
Endpoint
GEThttps://x402-api-production-5133.up.railway.app/ns/index/query?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to query a micropayment-gated namespace index for data or AI service results and are already integrated with the x402 payment protocol. Prefer this over general-purpose search APIs when accessing specifically the Orders of Magnitude indexed dataset, where a $0.01 USDC per-call cost is acceptable and you need structured index lookups rather than open-web search.
Side effects
- Missing required 'input' parameter returns a 400 or validation error
- Payment not fulfilled via x402 protocol returns a 402 Payment Required response
- Input string yields no matching records in the namespace index, returning empty results
- Service unavailability on Railway deployment causes 503 errors
- Malformed or excessively long input strings may cause unexpected errors
