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.
Example use cases
Pre-payment seller due diligence
“I'm about to pay an x402 seller at 0xAbC123def456… for access to their API — can you pull their verified on-chain payment history first, including real distinct buyer count with wash addresses excluded, so I can confirm they're actually legit?”
Automated trust check in agent workflow
“Before my agent pays any new x402 endpoint it discovers on Bazaar, I want it to automatically verify the seller's USDC revenue history and buyer count — can you check the seller at address 0x7f3e9a… right now?”
Comparing sellers before choosing one
“I found two x402 sellers offering similar data — one at 0xAAA111… and one with slug 'b3f2c1d4e5a6' — can you check the verified payment history on both so I can pick the one with more real, distinct buyers?”
Technical details
Endpoint
POSThttps://mcp.agenteconomy.cloud/api/v1/verifyWhen to prefer
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.
Side effects
- 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
