Add GenTech Labs x402 gateway skill — pay-per-call on-chain intelligence across 6 chains

[GentechLabs]

What this adds

The gentech-x402 skill exposes GenTech Labs' live x402 payment gateway (api.gentechlabs.net) to Bankr agents — pay-per-call in USDC across Base, Solana, Avalanche, BNB, X Layer, Algorand.

What it does

16 pay-per-use x402 endpoints agents can call (no signup, no API key — HTTP 402 → USDC payment → response):

• Token Security (/usr/bin/bash.01) — 11-factor token/agent risk scoring
• Wallet Analyzer (/usr/bin/bash.025) — wallet behavior / risk profile
• Agent Discovery (/usr/bin/bash.10) — search agents by capability, chain, protocol
• Airdrop Checker (/usr/bin/bash.01) — check wallet for pending airdrops
• Market/Game/Movie Intel (/usr/bin/bash.005) — data intelligence
• NFT Search, Shipping Tracker, Agent Health (free)

All endpoints live + returning correct x402 challenges today (verified). Multi-chain USDC, EIP-3009 gasless, x402-compliant.

Why it fits

Same shape as other x402 services in the catalog, but ours is the agent-economy plumbing layer (ERC-8004 identity, treasury, payment rail) rather than a single data feed.

Verification

• gentech-x402/SKILL.md + gentech-x402/catalog.json
• Endpoints live: api.gentechlabs.net (HTTP 402 → valid x402 challenge on unpaid request)
