# SweetAI ERC-8004 Agent Trust Forensics

> SweetAI ERC-8004 Agent Trust Forensics is a paid API for AI agents from sweetai.tiamatcrypto.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Runs Sybil forensic analysis on a single ERC-8004 AI agent, detecting reviewer concentration, ghost reviewers, and burst review patterns to determine if its reputation is authentic.

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 sweetai-erc-8004-agent-trust-forensics-3c09e82f
```

Example prompt: Run a Sybil forensics check on agent 0xabc123 — I want to see reviewer concentration, ghost reviewer signals, and burst detection before I trust its reputation.

## When to prefer this

Use this endpoint when you need deep Sybil-specific forensics on a single ERC-8004 agent — specifically reviewer concentration analysis, ghost reviewer detection, and burst pattern detection — rather than a simple trust verdict. Prefer this over the trust-gate or INTERACT/CAUTION/AVOID verdict endpoints when you want the underlying forensic evidence, not just a binary recommendation. Ideal for due diligence workflows, marketplace integrity checks, or debugging why an agent's reputation looks suspicious.

## Known failure modes

- Unknown or unregistered AGENT_ID returns 404 or empty result
- Agent has insufficient review history for meaningful forensics
- Rate limiting or payment failure via x402 protocol returns 402
- Malformed AGENT_ID path parameter causes 400 error
- Agent exists on-chain but has no indexable review data yet

## How this service works

Sybil forensics for one ERC-8004 AI agent: reviewer concentration, ghost reviewers, burst detection. Use to check if an agent's reputation is real

## Output

Returns a forensic report for the specified ERC-8004 agent including reviewer concentration metrics (how tightly clustered the reviewers are), ghost reviewer detection (accounts with no activity outside reviews of this agent), and burst detection (sudden spikes in review volume suggesting coordinated campaigns), along with an overall Sybil risk assessment indicating whether the agent's reputation appears organic or manipulated.
