How this service works
Pay-per-call endpoints over x402 v2 and MPP (the "Payment" HTTP auth scheme, method usdc). Includes counterparty compliance checks: /report/counterparty (company + registered parents + UN/OFAC/EU/UK sanctions, signed and verifiable), /screen/name and /screen/entity. Free: /health, /.well-known/x402, /receipts, /prove/keys, /prove/stats.
Output
Returns a JSON object with: a boolean 'ok' status, the energy grid identifier (e.g. 'ERCOT'), the endpoint type ('rwa-screen'), a numeric readiness score (0–1), the queried market name, a readiness label (e.g. 'ready'), a data source disclaimer, and a payment receipt containing the transaction hash, USD amount charged, and receipt ID.
Example use cases
Pre-investment RWA market screening
“Before I consider tokenizing energy assets, can you pull the RWA readiness score for the Florida market and tell me if it's ready?”
Comparing energy grid readiness across states
“I want to compare RWA readiness — can you screen both the Texas and Oregon energy markets and tell me their readiness scores?”
Due diligence for tokenized infrastructure fund
“We're building a report on tokenized US energy infrastructure. Can you screen the New York energy market for RWA readiness and return the grid info and score?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/rwa-screen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, scored readiness assessment for real-world asset tokenization in a specific US energy market and want a curated static reference with a clear readiness label. Prefer this over generic financial data APIs when the question is specifically about RWA tokenization readiness on known US energy grids (ERCOT, etc.) via pay-per-call x402 infrastructure.
Side effects
- Invalid or unsupported market value — only 'texas', 'florida', 'newyork', 'oregon' are accepted enum values
- Payment failure or insufficient USDC balance — returns HTTP 402 with payment required details
- Network or upstream timeout — endpoint may be temporarily unavailable
- Missing 'params' or 'market' field in request body — likely returns a 400 or error JSON
