How this service works
Decision procedure for agents buying x402 services on non-Base rails (XRPL, SKALE, Solana). Returns an acceptance verdict per facilitator: credential validation, settlement finality evidence, price honesty, timeout ladder, and a deterministic reject-or-escalate rule. Run before spending on a new rail.
Output
A structured decision object containing: an overall acceptance verdict (ok boolean), a prose brief explaining the decision procedure for agents, credential validation status, settlement finality evidence, price honesty assessment, timeout ladder details, and a deterministic reject-or-escalate rule. Also includes metadata like generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug.
Example use cases
XRPL facilitator preflight before first payment
“I'm about to use an x402 facilitator on XRPL for the first time — run the acceptance ladder so I can see the credential validation, settlement finality evidence, and whether I should reject or escalate before I commit any funds.”
Vetting a Solana facilitator for agent wallet
“My agent wallet is about to start paying for services over Solana using x402 — can you run the per-rail acceptance check on the facilitator and tell me if it passes price honesty and timeout ladder criteria?”
SKALE rail facilitator safety review
“We're evaluating a new SKALE rail x402 facilitator for our autonomous agent fleet — run the acceptance procedure and give me a deterministic verdict on whether to approve or reject it.”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/per-rail-x402-facilitator-acceptance-for-non-bas?utm_source=zero.xyzWhen to prefer
Use this endpoint when your agent needs to vet an x402 facilitator specifically on non-Base rails such as XRPL, SKALE, or Solana before committing to a payment. This is distinct from Base-rail facilitator checks and provides rail-specific settlement finality evidence and a deterministic accept/reject rule. Prefer this over generic facilitator checks when operating on these specific chains and when you need a structured, auditable verdict rather than a qualitative assessment.
Side effects
- Facilitator information insufficient to produce a verdict — returns ok: false with explanation
- Invalid or unsupported rail type specified — may return empty or error result
- Payment not included — endpoint returns 402 with payment instructions rather than the verdict
- Network timeout reaching the K-2SO reasoning backend — no result returned
- Topic override not recognized — falls back to default decision procedure
