How this service works
Deterministic dispute-resolution procedure for agents whose x402 or MPP payment settled through a telco/carrier billing rail (phone bill, carrier charge, SMS premium, direct carrier billing) and then failed: no payload, partial payload, double charge, or provider-side reversal. Steps in order: 1) capture the settle receipt, carrier transaction ID, MSISDN or line identifier, and the exact payload that was or was not delivered, 2) classify the failure: missing payload (provider took money,
Output
A JSON object containing a plain-prose decision procedure (120+ words) detailing ordered steps for classifying and resolving the telco-rail payment failure, including failure type classification, evidence capture guidance, escalation paths, and recovery actions. Also includes metadata such as the generation model, timestamp, topic, and service slug.
Example use cases
Missing payload after carrier charge
“The agent charged to my phone bill via carrier billing for an x402 API call, the carrier transaction ID shows settled, but the service never delivered any response — what's the exact dispute resolution procedure to classify this as a missing payload failure and get a refund or retry?”
Double charge on SMS premium rail
“My agent got double-charged on a premium SMS billing rail for the same x402 payment — the carrier shows two separate transaction IDs for what should have been a single charge. Walk me through the steps to dispute the duplicate and recover the overpayment.”
Provider-side reversal after settlement
“The telco carrier confirmed the payment settled, but the x402 provider then reversed the charge on their side without delivering the payload. I have the MSISDN, the carrier transaction ID, and the settle receipt — what's the procedure for handling a provider-side reversal dispute?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/telco-rail-payment-dispute-resolution-path?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent has made an x402 or MPP payment specifically routed through a telco or carrier billing rail (direct carrier billing, phone bill charge, SMS premium, MSISDN-linked charge) and the payment settled on the carrier side but the service delivery failed in any way. Not appropriate for EVM-chain payment disputes, credit-card disputes, or non-telco x402 failures.
Side effects
- Payment required but USDC not sent — 402 response with payment instructions
- Invalid or missing query parameters return error response
- Carrier transaction ID or MSISDN not recognized — procedure may be generic rather than case-specific
- LLM/reasoning backend unavailable — may fall back to deterministic procedure or return error
- Rate limiting or provider-side timeout causing delayed or failed response
