Agent-Native Privacy Payment Selection Decision Procedure
x402
Agent-Native Privacy Payment Selection Decision Procedure 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 2026-10-20).
Returns a structured decision procedure helping an AI agent determine whether a payment or data transfer needs privacy rails and which privacy technology to use (Monero, Railgun, Aztec, or plain USDC).

How this service works
Decision procedure for an AI agent deciding whether a payment or data transfer needs privacy rails and which one to use. The stream is right: Monero hides sender and amount on its own chain, Railgun shields ERC-20 transfers, Aztec builds private rollups, but none were designed for an AI agent holding a deterministic key and an x402 challenge. Ordered workflow: score the transaction's privacy need tier (0 plain pseudonymous USDC is enough, 1 shielded amount but public sender, 2 hidden sender and
Output
A JSON object containing a decision procedure prose brief for the agent, the recommended privacy tier and rail, the topic evaluated, an ISO-8601 timestamp, and the generation source (llm, reasoning, or deterministic), along with payment confirmation fields.
Example use cases
Hiding agent identity on DeFi transfer
“I'm an autonomous agent about to make a cross-chain transfer and I need to know if plain pseudonymous USDC is enough or if I should route through Aztec or Monero to hide my wallet identity — can you run the privacy rail selection procedure for me?”
Choosing shielded ERC-20 rail for sensitive payment
“My agent needs to send an ERC-20 token payment where the amount should be private but the sender doesn't need to be hidden — which privacy rail should I use, Railgun or something else? Run the agent-native privacy payment selection decision procedure.”
Evaluating privacy requirement before x402 settlement
“Before my agent approves an x402 payment challenge, I want to score the transaction's privacy need — is this a tier-0 plain USDC situation, tier-1 shielded amount, or tier-2 fully hidden sender and amount? Can you walk me through the decision procedure?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-native-privacy-payment-selection-procedur?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a structured, opinionated decision framework for choosing a privacy rail for payments or data transfers in the x402 ecosystem. Prefer it over ad-hoc logic when the agent must systematically evaluate sender visibility, amount visibility, and chain compatibility before committing to a payment route. Especially valuable when the agent holds a deterministic key and faces an x402 challenge where naive USDC would leak metadata.
Side effects
- Payment not provided — returns HTTP 402 requiring x402 payment of $0.002 USDC
- Invalid query parameters — unrecognized topic or method returns an error
- Service unavailable — upstream LLM or reasoning engine offline
- Empty or malformed response if the handler fails (ok: false in result)
