How this service works
Decision procedure for an agent on either side of a contested x402 payment: merchant failed to deliver, delivered partial or wrong content, double-charged, or went silent after taking payment. Ordered workflow: freeze evidence first (challenge body hash, payment tx hash, delivery receipt, request and response logs, timestamps), classify the dispute, run the recover-first ladder (idempotent re-request, re-negotiate, refund request, then escalate), and gate every escalation on a cost-benefit
Output
A prose decision procedure brief tailored to the dispute scenario, including ordered workflow steps (evidence freezing, dispute classification, recover-first ladder, cost-benefit escalation gating), plus metadata: service slug, generation source (llm/reasoning/deterministic), model used, and ISO-8601 generation timestamp.
Example use cases
Non-delivery dispute after silent merchant
“My agent paid an x402 merchant but received no response and the merchant has gone silent — what's the ordered procedure to freeze my payment evidence and attempt recovery before I escalate?”
Wrong content delivered after x402 payment
“The x402 service took my payment but delivered completely wrong content — give me the step-by-step dispute workflow to classify this, attempt a renegotiation or refund, and decide whether escalation is worth the cost.”
Double-charge detected on x402 transaction
“I can see two payment transaction hashes charged for the same x402 request — what's the decision procedure I should follow to document the double-charge and recover the duplicate payment?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-facing-x402-payment-dispute-resolution-pro?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent is actively involved in an x402 payment dispute — either as buyer or merchant — and needs a structured, ordered decision procedure rather than general payment advice. It is specifically optimized for x402 protocol disputes with evidence-freezing, classify-then-recover logic, and cost-gated escalation, making it more actionable than a generic dispute FAQ or a human-facing legal resource.
Side effects
- Missing required input fields returns a validation error
- Payment not included results in a 402 response requiring USDC payment before access
- Invalid topic override may return a generic rather than scenario-specific procedure
- Downstream LLM unavailability may cause generation failure or degraded response
- Rate limiting or network issues on the ascii.dev host may cause timeouts
