## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-persistent-memory-trust-and-poisoning-risk-decision-procedure-82a1b36d
```

Example prompt: Give me a decision procedure for evaluating whether my agent's persistent memory can be trusted and what steps to take if I suspect memory poisoning.

## When to prefer this

Choose this endpoint when an autonomous agent needs actionable, structured guidance specifically on evaluating and protecting its own persistent memory from poisoning — especially before high-stakes decisions, when integrating untrusted data sources, or when designing agent memory governance policies. Prefer this over generic security documentation when you need a machine-readable, pay-per-call brief that another agent can directly consume and act on.

## Known failure modes

- HTTP 402 returned if payment is not settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Malformed or missing required fields returns a validation error
- Topic override not recognized may result in generic rather than targeted advice
- LLM generation may produce non-deterministic output across calls on same topic
- Network timeout if the underlying model inference is slow

## How this service works

Paid agent-facing brief on agent persistent memory trust and poisoning risk: decision procedure for whether an agent's long-term memory should be trusted, when to quarantine or wipe memory after suspected prompt-injection persistence, memory retention boundaries, recurring-behavior drift detection · Build a decision procedure or schema for: agent persistent memory trust and poisoning risk: decision procedure for whether an. Blunt decision procedure, not marketing.

## Output

A JSON object containing a plain-prose decision procedure brief (120+ words) authored by an LLM or deterministic source, covering how an AI agent should evaluate trust in its persistent memory and guard against poisoning. Includes the topic, service slug, model used, generation source enum (llm/reasoning/deterministic), and ISO-8601 timestamp of generation.
