# Agent Memory API – Trust Verify

> Agent Memory API – Trust Verify is a paid API for AI agents from agent-memory-api-bix5.onrender.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Analyzes agent-generated content for trustworthiness, returning a trust score, hallucination risk level, verdict, and a recommended next API call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-memory-api-trust-verify-7a4e349e -d '<json body>'
```

Example prompt: Can you verify whether this output from my research agent 'ResearchBot-v2' is trustworthy? The content is: 'The GDP of Japan grew by 3.2% in 2023 due to increased exports.' — I want to know the trust score, whether there's a hallucination risk, and what you recommend I do next.

## When to prefer this

Use this endpoint when an AI agent needs to validate its own or another agent's output before acting on it — especially in multi-agent pipelines where hallucination risk must be quantified. Prefer this over generic content moderation APIs when you need a numeric trust score plus a chained API recommendation specific to AI agent workflows.

## Known failure modes

- Missing required fields (content or source_agent) returns 422 validation error
- Payment not included or insufficient USDC results in 402 payment required
- Service unavailable on Render cold start returns 503 or timeout
- Malformed JSON body returns 400 bad request
- Extremely long content strings may be truncated or rejected

## How this service works

Pay-per-request encrypted memory APIs for autonomous AI agents using x402. Store, recall, and audit AI agent memory with AES-256 encryption. Built for USDC/Base payments and Japanese AI agent workflows.

## Output

Returns an integer trust score, a hallucination risk classification (e.g. low/medium/high), a verdict string, an array of warning messages, and a next_recommended object pointing to another API with its URL, reason, expected improvement, and price in USDC.
