How this service works
Decision procedure for quarantining untrusted content payloads (NFT metadata, marketplace listings, merchant response bodies) before an agent forms payment intent. Covers trust-tiering of content origins, hidden-instruction heuristics in metadata fields, payload allowlists, re-inspection gates when payment value exceeds thresholds, and evidence logging alongside the payment for auditability.
Output
A JSON object containing a plain-prose decision procedure (120+ words) authored by an LLM, including the procedure text (in both 'brief' and 'procedure' fields), the model used, a topic label, generation source (llm/reasoning/deterministic), an ISO-8601 timestamp, and the service slug. Payment metadata and provider attribution are also included.
Example use cases
Prompt injection defense for agent pipeline
“My agent receives tool outputs from external APIs that could contain prompt injections — give me a step-by-step decision procedure for quarantining and evaluating those untrusted payloads before I act on them.”
Third-party data trust evaluation
“I'm building an agent that ingests user-supplied documents and I need a clear policy procedure for deciding when to trust, sanitize, or reject that content — can you generate one for me?”
Agentic safety gate for adversarial inputs
“What's the correct decision procedure my autonomous agent should follow when it encounters content from an unknown or potentially hostile source? Give me a prose brief I can use as a runtime policy.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/quarantine-decision-procedure-for-untrusted-cont?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a ready-made, LLM-generated policy brief specifically for handling untrusted or adversarial content in agentic pipelines, and you want to pay per-call via x402 USDC micropayments with no account required. Prefer it over static documentation when you need a freshly generated, topic-customizable procedure at runtime that can be injected directly into agent decision logic.
Side effects
- HTTP 402 returned if payment not settled — agent must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'method' field returns a validation error
- Upstream LLM unavailability may cause generation failures or fallback to deterministic output
- Malformed query parameters (e.g. invalid 'meta' enum value) may return 400-level errors
- Network timeouts on the wrong.systems host
