## 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 agenteconomy-cloud-seller-verification-a3049ee4 -d '<json body>'
```

Example prompt: Before I pay this x402 seller at 0xAbC123…, can you verify their actual on-chain payment history — real USDC revenue, distinct buyers, wash trading excluded — so I know they're legitimate?

## When to prefer this

Choose this endpoint when an AI agent needs to make a trust decision about an x402 seller before executing a payment — specifically when you need auditable, on-chain verified USDC revenue and real distinct buyer counts rather than an opaque trust score or simple liveness check. Prefer this over generic reputation APIs when the seller operates on the Base blockchain x402/Bazaar ecosystem and you need wash-trading-excluded, Ed25519-signed data that can be independently verified from public chain data.

## Known failure modes

- Unknown seller address — no indexed payment history found for the given 0x address or slug
- Invalid input format — seller field must be a valid 0x address or exactly 12-hex slug
- Seller has zero qualifying payments — returns verified zero history, not an error
- Upstream Base indexing lag — very recent transactions may not yet be reflected
- $0.10 USDC payment failure — x402 payment not completed, call rejected

## How this service works

Is this x402 seller safe to pay? Verify before you send money: one call returns the seller's actual on-chain payment history — verified USDC revenue, real distinct buyers, wash and exchange exclusions applied — not a liveness ping or an opaque score. Ed25519-signed, recomputable from public Base data. From the trust hub that indexes every Bazaar seller's payment history. Never in your payment path. agenteconomy.cloud (mcp-pricing-v1.1)

## Output

An Ed25519-signed payload containing the seller's verified on-chain USDC revenue total, count of real distinct buyers (with wash trades and exchange addresses excluded), and supporting payment history data — all recomputable from public Base blockchain data. The response is not a liveness ping or opaque score, but auditable transaction-level evidence.
