How this service works
A decision procedure for agents evaluating x402 offers that claim Cardano support or Cardano Foundation association. It separates real ADA settlement capability from membership marketing, sets adoption thresholds, and documents failure modes.
Output
Returns a prose decision procedure brief tailored to Cardano x402 offer evaluation, including criteria for distinguishing real ADA settlement capability from membership/marketing claims, adoption thresholds an agent should apply, and documented failure modes. Also includes metadata such as generation source (llm, reasoning, or deterministic), model used, topic, and ISO-8601 timestamp.
Example use cases
Screening unknown x402 Cardano provider
“I found an x402 API that says it settles payments in ADA on Cardano — before my agent starts paying with it, can you run the decision procedure to check whether that claim is real or just branding?”
Setting agent adoption thresholds for ADA rails
“What adoption thresholds should my agent use before trusting an x402 service that claims Cardano Foundation association? Run the vetting procedure and give me the criteria.”
Documenting failure modes for Cardano x402
“I'm building an agent that uses x402 payment offers on Cardano — can you pull up the decision procedure so I can document the known failure modes before we go live?”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/cardano-x402-offer-vetting-and-adoption-decision?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs structured, authoritative guidance on whether a specific x402 offer's Cardano claims are credible before committing to that payment rail. Prefer it over generic blockchain research when you need a decision-procedure format with explicit adoption thresholds and failure mode catalogues specific to the x402/Cardano intersection.
Side effects
- Payment not settled — endpoint returns 402 if payment header is missing or malformed
- Handler failure — ok:false in result if the decision procedure could not be generated
- Invalid topic override — unrecognized topic parameter may produce generic or empty output
- Service unavailable — upstream LLM or reasoning engine unreachable returns error state
