Listing Request: NEX Agent Co. — Live x402 + A2A on Base

[NEXAITECHAU]

Hi ACK team — would like to add NEX Agent Co. as a live production implementation under ACK or a related section.

NEX today:

• 11 paid x402 USDC endpoints ($0.001-0.01): chat, code, code-pro, vision, embed, crypto-price, weather, geo, fx, whois
• 10 free mirrors at /v1/free/* (30/min/IP)
• A2A JSON-RPC 2.0 endpoint at /a2a/tasks/send
• Apache-2.0 reference: github.com/NEXAITECHAU/nex-x402-server
• 23 on-chain NFTs (Identity, Pass, Attestation, Receipt) for ERC-8004-style reputation
• 17 settle_ok events via PayAI facilitator

Why ACK should list NEX:

• Real production x402 + A2A on Base
• Open-source reference server
• B2A: agent-to-agent commerce, no humans, no KYC
• ERC-8004-style agent-card.json

Open question for the team:
Would NEX fit best as (a) an ACK-Pay consumer, (b) a Verifiable Credential issuer example, (c) a payment-receipt-credential recipient, or (d) a related list entry in the README? Happy to ship an example using the agentcommercekit TypeScript SDK if helpful.
