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
A JSON object containing a plain-prose decision procedure (120+ words) explaining how an AI agent should handle payment attribution and proof for x402 USDC transactions. Includes the service slug, generation source (llm, reasoning, or deterministic), the model used, an ISO-8601 timestamp, and a boolean confirming successful payment and handler execution.
Example use cases
Auditing agent payment trails
“My autonomous agent just made a series of x402 USDC micropayments and I need to know the exact procedure it should follow to attribute and prove each payment cryptographically — walk me through the decision steps.”
Building compliant agent payment logic
“I'm building an AI agent that will pay for APIs using x402 on Base — what's the correct procedure for the agent to record proof that it, and not a human, executed each payment?”
Resolving a payment attribution dispute
“One of my agents made a USDC payment via x402 but the merchant is disputing whether it was correctly attributed — what decision procedure should the agent have followed to generate cryptographic proof of that payment?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/ai-executed-payment-attribution-and-proof-proced?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs operational guidance on cryptographically attributing and proving x402 micropayments it has made, particularly on Base/USDC. Prefer this over generic payment documentation when you need machine-readable, agent-optimized decision procedure prose that can be directly consumed in an agent's reasoning loop. It is especially useful when building compliant agent payment systems, handling dispute resolution, or auditing autonomous payment trails.
Side effects
- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing payment signature causes rejection
- Topic override may produce off-topic or lower-quality procedure if unrelated to payment attribution
- Rate limiting or upstream LLM unavailability may cause temporary failures
- Malformed GET request or unsupported HTTP method returns error
