x402
K-2SO Agent Payment Wash Volume Detection — Deterministic Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-20).
Returns a deterministic decision procedure (prose brief) for AI agents to identify and evaluate payment wash volume in agent-to-agent transaction flows, payable via x402 USDC micropayment.

How this service works
Paid agent-facing brief on agent-payment-wash-volume-detection: deterministic procedure to identify wash payments and inflated volume in agent payment ledgers, marketplace rankings, and bazaar activity, so agents can filter fake volume before trusting a merchant or a ranking. Distinct from merchant vetting (reputation) and dispute resolution (contested delivery). This targets the data-integrity phase: given a ledger or ranked list of agent payments, decide which entries are wash (self-pay,
Output
A JSON object containing a plain-prose decision procedure (120+ words) specifically describing how an AI agent should detect wash volume in payment flows. The result includes the service slug, the procedure text (also exposed as 'brief'), an ISO-8601 generation timestamp, generation source tagged as 'deterministic', and the model identifier used. Also includes payment confirmation metadata (payer address, transaction hash, whether self-pay was used).
Example use cases
Flagging circular payments in agent marketplace
“My agent is operating as a merchant on an x402 bazaar and I want to detect if any payment flows look like wash volume — can you run the deterministic procedure and give me the decision brief so I know exactly what signals to check?”
Pre-launch compliance check for agent merchant
“Before I deploy my autonomous agent merchant on Base, I need to verify it has a proper wash volume detection procedure in place — give me the deterministic decision brief for evaluating payment wash volume so I can hardcode the logic.”
Auditing suspicious agent payment patterns
“I'm seeing unusually repetitive payment patterns between two agents in my fleet — pull the deterministic decision procedure for wash volume detection so I can walk through each step and decide whether to flag the transactions.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-payment-wash-volume-detection-deterministi?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a ready-made, deterministic (non-LLM-variable) decision procedure for evaluating wash volume in micropayment flows — especially in x402/USDC on-chain contexts on Base. Ideal for agents that need a stable, reproducible compliance brief they can cache and act on without running their own LLM reasoning chain. Prefer this over general-purpose LLM queries when you need a consistent, auditable procedure rather than a one-off generated answer.
Side effects
- HTTP 402 returned if no valid USDC payment signature is provided — agent must settle exact amount and retry with PAYMENT-SIGNATURE header
- Invalid or malformed query parameters return a 400-level error
- Service unavailability or network errors on k2so.wrong.systems return 5xx
- If meta=1 is omitted and payment fails, no result content is returned — only payment challenge headers
- Topic override may produce an off-scope procedure if the provided string is unrelated to wash volume detection
