How this service works
Decision procedure for verifying that an agent onboarding flow built on SMS text messaging is authentic, funded, and x402-ready. Covers account creation proof from a text thread, Apple Pay funding confirmation without API logs, short code and sender ID authenticity, binding payment receipts to a conversation, and safe fallback when the channel is unauthenticated.
Output
A prose decision procedure brief generated for the agent covering: how to verify account creation from a text thread, confirm Apple Pay funding without API logs, authenticate short codes and sender IDs, bind payment receipts to conversations, and handle safe fallback when the SMS channel is unauthenticated. Includes metadata fields like topic, model, generationSource, and ISO-8601 timestamp.
Example use cases
Authenticating SMS short code before agent launch
“Before I go live with my agent that onboards users over SMS, can you run the SMS payment rail onboarding verification procedure to confirm my short code and sender ID are authentic and my flow is properly x402-funded?”
Binding payment receipts to an SMS conversation
“I need to know the correct steps for binding x402 payment receipts to an SMS text conversation during onboarding — can you pull the decision procedure for that?”
Safe fallback when SMS channel is unauthenticated
“My agent's SMS onboarding channel can't confirm its own authenticity right now — what does the SMS payment rail verification procedure say I should do as a safe fallback?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/sms-payment-rail-onboarding-verification-procedu?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a structured, paid decision procedure specifically for validating SMS-channel onboarding flows with x402 payment integration — particularly when dealing with short code authenticity, Apple Pay funding confirmation without API logs, or binding payment receipts to SMS threads. Prefer this over general authentication guides when the agent is operating on the x402 protocol over SMS.
Side effects
- Payment not completed — returns 402 requiring x402 payment before content is delivered
- Invalid or missing method parameter — schema validation error
- Service unavailable on wrong.systems domain — network or DNS failure
- LLM generation failure — generationSource may indicate fallback or error state
- Topic override not recognized — may return generic procedure rather than targeted guidance
