AI-Executed Payment Attribution and Proof Procedure Brief
x402
AI-Executed Payment Attribution and Proof Procedure Brief is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Returns a paid decision-procedure brief explaining how an AI agent cryptographically binds its identity to an x402 payment to prove the payer was an autonomous agent, and how to handle legacy unattributable payments.

How this service works
Paid agent-facing brief on AI-executed payment attribution and proof procedure: how an agent cryptographically binds its identity to an x402 payment so it can later prove the payer was an autonomous AI, not a human, and how to handle legacy payments that cannot be retroactively attributed. Blunt decision procedure, not marketing.
Output
Returns a structured JSON response containing a prose decision-procedure brief ('brief' field) with step-by-step guidance on cryptographic identity binding for x402 agent payments, handling of legacy unattributable payments, the service slug, generation source (llm/reasoning/deterministic), an ISO-8601 timestamp, and payment metadata including payer address and transaction reference.
Example use cases
Proving agent-initiated payment origin
“I need to understand exactly how my AI agent should cryptographically bind its identity to an x402 payment at the time of execution, so that downstream systems can verify the payer was autonomous — can you get me the full decision procedure?”
Auditing unattributable legacy payments
“Some of my agent's older x402 payments don't have any attribution data attached — what's the recommended procedure for handling those legacy payments that can't be retroactively attributed?”
Building agent payment compliance workflow
“I'm designing a compliance workflow for my agent fleet and need a blunt decision procedure explaining how agents should prove their payment identity on x402 so we can satisfy audit requirements — fetch that brief for me.”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/ai-executed-payment-attribution-and-proof-procedWhen to prefer
Choose this endpoint when an autonomous agent needs authoritative, structured guidance on x402 payment attribution and cryptographic identity proof — specifically the blunt procedural steps without marketing fluff. Prefer over general documentation when you need machine-consumable decision logic, need to handle the legacy payment edge case explicitly, or when operating within a multi-agent fleet that must produce auditable proof of autonomous payment origin.
Side effects
- Payment not completed — returns 402 with payment details required before content is delivered
- Invalid or missing method parameter — returns schema validation error
- Topic override not recognized — may return generic procedure rather than scoped answer
- Service temporarily unavailable — upstream LLM or reasoning engine error
- Rate limiting or provider-side error from K-2SO infrastructure
