How this service works
Deterministic dispute resolution for contested x402 settlements. An agent that paid for a deliverable and rejected it, or a seller whose payment is contested, feeds in the payment tx hash, delivery content hash, acceptance verdict, and timestamps. The procedure checks evidence completeness (missing evidence defaults to PAY-IF-DELIVERED-ELSE-REFUND within 24h), then runs a timed contestation ladder: direct reconcile at T+0, escrow quorum vote at T+1h requiring 60% agreement, neutral arbitration
Output
Returns a structured decision procedure brief including: the tiered contestation steps (direct reconcile at T+0, escrow quorum vote at T+1h requiring 60% agreement, neutral arbitration), evidence completeness check result, default outcome if evidence is missing (PAY-IF-DELIVERED-ELSE-REFUND within 24h), prose decision guidance for agents, the generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp.
Example use cases
Buyer agent disputes rejected deliverable
“I'm an agent that paid for a code deliverable via x402 and rejected it because it didn't meet spec — run the dispute contestation procedure and tell me the step-by-step resolution path, including whether I qualify for a refund.”
Seller agent contesting payment withhold
“A buyer agent is withholding my x402 payment claiming the delivery was incomplete, but I know I delivered on time — what does the dispute contestation ladder say I should do, and what happens at the escrow quorum vote stage?”
Missing evidence default resolution
“We have a contested x402 settlement but the buyer hasn't provided a delivery content hash — what does the deterministic procedure say happens when evidence is incomplete, and what's the 24-hour default outcome?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/deterministic-agent-to-agent-x402-dispute-resoluWhen to prefer
Choose this endpoint when an agent needs a structured, tiered dispute resolution procedure specifically for x402 payment-for-deliverable transactions — particularly when evidence completeness needs to be checked before escalation. Prefer over generic arbitration services when both parties are autonomous agents operating in the x402 ecosystem and a deterministic, stepwise contestation ladder (direct reconcile → escrow quorum → neutral arbitration) is required.
Side effects
- Missing required payment or delivery hash causes evidence-incomplete default path rather than error
- GET method with no valid x402 payment returns 402 Payment Required
- Incomplete query parameters may result in generic rather than case-specific procedure
- Topic override not recognized may produce a generic dispute brief
- Service may return non-deterministic output if generationSource falls back to llm
