How this service works
Deterministic decision procedure for how much payment metadata an agent leaks when it pays. Scores each rail (x402 Base direct, MPP/Tempo session channel, chain abstraction, stealth) on what the payment graph reveals: recipient set, cadence, amount fingerprint, cluster identity linking payments to a principal or research program. Returns an exposure grade per rail, routing verdict (direct / session / segmented wallet / escalate-to-principal), and kill criteria: never reuse one wallet across
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) tailored to agent payment metadata privacy and exposure, including the generation model, ISO-8601 timestamp, generation source (llm/reasoning/deterministic), and service/provider identifiers. The 'brief' and 'procedure' fields contain actionable guidance agents can parse and act on directly.
Example use cases
Privacy routing for agent-to-agent payments
“My AI agent is selling APIs over x402 and I want to know what payment metadata it should expose or keep private — give me a decision procedure so it handles this correctly.”
Audit trail policy for x402 merchant agent
“I'm building an autonomous merchant on Base that accepts USDC micropayments — what's the right decision procedure for deciding which payment metadata fields to log vs. keep confidential?”
Buyer-side payment data handling guidance
“My agent buys services from x402 merchants and I need a clear procedure for how it should treat the payment signatures and transaction data it sends — what should it expose to downstream services?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-payment-metadata-privacy-and-exposure-deciWhen to prefer
Choose this endpoint when an autonomous agent needs structured, LLM-generated guidance specifically on how to handle privacy and disclosure of x402 payment metadata — particularly for agents operating as merchants or buyers on Base with USDC. Prefer this over generic compliance or privacy APIs when the context is specifically x402 protocol payment flows and agent-to-agent commerce.
Side effects
- HTTP 402 returned if payment not settled before retry — agent must pay exact USDC amount and resend with PAYMENT-SIGNATURE header
- Payment signature mismatch or expired signature results in rejection
- Invalid or unsupported HTTP method returns error
- topic override query param ignored or misformatted may result in default topic being used
- Service temporarily unavailable on k2so.wrong.systems returns 5xx
