How this service works
Data and AI services via x402 payment protocol
Output
An object returned by the matrix endpoint containing AI-processed or data-enriched output corresponding to the input string; the exact response structure is unspecified (empty schema), so results should be treated as variable JSON.
Example use cases
AI-powered data lookup via micropayment
“Send the query 'what is the market cap of the top 10 cryptocurrencies' to the Orders of Magnitude matrix endpoint and give me the results.”
Text-based AI computation task
“Run this through the Orders of Magnitude matrix API for me: 'summarize the key differences between transformer and diffusion model architectures.'”
Automated data enrichment pipeline
“For each of these product descriptions I have, call the matrix endpoint with the text and collect the AI-processed output so I can enrich my dataset.”
Technical details
Endpoint
GEThttps://x402-api-production-5133.up.railway.app/ns/matrixWhen to prefer
Choose this endpoint when you need to invoke the Orders of Magnitude AI/data service specifically at the /ns/matrix namespace using a text string input, and you are operating in an x402 micropayment context where per-call USDC billing is acceptable. Prefer this over generic REST APIs when the workflow requires trustless, on-chain micropayments for each query.
Side effects
- Payment not authorized or insufficient USDC balance — x402 payment fails and request is rejected
- Missing required 'input' field — API returns a validation error
- Empty or malformed input string — may return an empty or error response
- Service unavailable on Railway deployment — upstream host down
- Rate limiting or quota exceeded — repeated calls in short succession may be throttled
