ZK-Proof-Gated Settlement Acceptance Decision Procedure
x402
ZK-Proof-Gated Settlement Acceptance Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-31).
Returns a blunt, agent-facing decision procedure for when to accept ZK-proof-gated settlement versus plain x402 payment execution, including how to verify proofs, which circuits to trust, and when to demand proof before paying.

How this service works
Decision procedure for agents choosing between plain x402 calls and ZK-proof-gated settlement. When a provider offers atomic proof-verified delivery, this procedure tells you: (1) whether the proof type matches the claimed execution (circuit pinning, verification key check, proof standard), (2) which circuit/verifier sources are trustworthy enough to accept, (3) when plain payment is acceptable (low value, idempotent, replayable) versus when you must demand proof before paying (high value,
Output
A structured prose brief containing: a blunt decision procedure for accepting ZK-proof-gated settlement vs plain x402 execution; steps for how an agent verifies a ZK proof from a provider; criteria for which circuits to trust; conditions under which plain x402 payment is acceptable; and conditions under which the agent must demand proof before paying. Also includes the generation source (llm/reasoning/deterministic), model used, and ISO-8601 timestamp.
Example use cases
Evaluating atomic proof-verified delivery offer
“A provider is offering me atomic proof-verified delivery with a ZK settlement gate — walk me through exactly when I should accept that versus just paying plain x402, and how I verify the proof is legit before I commit funds.”
Building agent circuit trust policy
“I'm building an agent that receives x402 settlement offers from unknown providers — give me a decision procedure for which ZK circuits I should trust and which I should reject outright, with no marketing fluff.”
Gating high-value payments behind proof requirement
“My agent is about to make a high-value x402 payment and the provider says they support ZK-proof-gated settlement — what's the step-by-step procedure for deciding whether to demand proof before paying versus just executing the plain payment?”

Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-decision-procedure-for-accepting-zk-proof?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a concrete, non-marketing decision procedure for evaluating ZK-proof-gated settlement offers in x402 contexts — specifically when the agent must decide at runtime whether to require cryptographic proof of delivery before releasing payment, or when building a trust policy for ZK circuits. Prefer this over generic ZK documentation when you need agent-executable logic rather than explanatory prose.
Side effects
- Payment not included — returns 402 requiring $0.002 USDC via x402 before content is served
- Invalid or missing 'method' field in input schema — returns validation error
- Topic override not recognized or out of scope — may return generic procedure rather than topic-specific guidance
- Provider backend unavailable — returns error with no brief generated
- Malformed request body — returns schema validation failure
