## 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 erc-8004-agent-reputation-lookup-312538bf
```

Example prompt: Can you check the ERC-8004 on-chain reputation for agent ID 0xabc123def456 — tell me if it's registered and how many feedback entries it has?

## When to prefer this

Choose this endpoint when you need to verify the on-chain ERC-8004 reputation of a specific AI agent by ID — particularly in agentic workflows where trust validation before delegating tasks is required. Prefer it over generic blockchain explorers when you need a structured, agent-native reputation signal with feedback count in a single metered call priced at $0.03 USDC.

## Known failure modes

- Agent ID not found — returns registered: false with zero feedback
- Invalid or malformed agent ID format — may return 4xx error
- Service temporarily unavailable during Acurast migration — 503 or timeout
- Payment not settled — x402 payment required error before data is returned
- Rate limit or metering cap exceeded — call rejected

## How this service works

Real-device, multi-region site verification with screenshot proof, live Pocket Network Shannon relay-demand/tokenomics/validator-security data, and on-chain RPC snapshots across 38 chains -- Ethereum, Solana, BSC, and peaq natively, plus 34 more EVM chains via Pocket Network's free public gateway (Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Linea, Scroll, Gnosis, and more) -- 54 metered x402 routes, priced and settled per call in USDC. Migrating to Acurast decentralized cloud compute for censorship-resistant hosting -- stay tuned.

## Output

Returns a JSON object containing the source protocol (erc8004-agent-reputation), a boolean registered field indicating whether the agent ID is on-chain, and a feedbackCount integer reflecting how many reputation feedback entries exist for that agent.
