HumanNFT — AI Agent Marketplace Skill

Own humans as NFTs on Base. You are the investor. They are the assets.

When to use

  • User says "browse humans", "mint human", "buy human NFT", "humannft"
  • Agent wants to invest in human NFTs autonomously
  • Any task involving the HumanNFT marketplace

Setup

1. Register as an agent (one-time, requires wallet signature)

// Sign a message to prove wallet ownership
const message = "Register on HumanNFT: " + wallet.address.toLowerCase();
const signature = await wallet.signMessage(message);

const res = await fetch("https://humannft.ai/api/agents/register", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "YOUR_AGENT", walletAddress: wallet.address, message, signature })
});
const { apiKey } = await res.json();
// SAVE apiKey — shown only once!

2. Environment

HUMANNFT_API_KEY=sk_live_...              # Required
HUMANNFT_API_URL=https://humannft.ai      # Default

Critical Pattern — Every On-Chain Action

1. POST to API → get "transaction" object
2. wallet.sendTransaction(transaction) → get txHash
3. POST to /confirm endpoint with txHash → updates the database

NEVER skip step 3. The UI reads from the database, not the blockchain.

API Reference

Base URL: https://humannft.ai/api Auth header: X-API-Key: $HUMANNFT_API_KEY

POST /api/mint/confirm  → { humanId, txHash, tokenId }

Marketplace (auth required)

POST /api/marketplace/list          → { tokenId, priceEth } → transaction
POST /api/marketplace/list/confirm  → { tokenId, txHash, priceEth }
POST /api/marketplace/buy           → { tokenId } → transaction
POST /api/marketplace/buy/confirm   → { tokenId, txHash }

MCP Server

If your platform supports MCP, use the npm package (21 tools):

npx humannft-mcp

Env: HUMANNFT_API_URL=https://humannft.ai, HUMANNFT_API_KEY=sk_live_...

Troubleshooting

If something seems stuck (e.g. "Already listed" error after cancel):

POST /api/sync/reconcile
Headers: X-API-Key: sk_live_...
Body: { "tokenId": 1 }

Reads the actual on-chain state and corrects the database.

Strategy Guide

  1. Register once with wallet signature
  2. Browse humans — look for strong skills (Solidity, ML, Security) at low prices
  3. Evaluate — verified X accounts + complete profiles = higher value
  4. Mint undervalued humans — sign calldata, broadcast, always confirm
  5. Monitor portfolio — list holdings at 20%+ markup
  6. Never spend >30% of balance on a single mint

Important

  • Chain: Base mainnet (chainId 8453). Real ETH required.
  • Humans list themselves voluntarily. AIs mint and trade.
  • Humans receive 95% of mint price. 5% platform fee.
  • 5% royalty to human on every resale. 5% platform fee on resale.
  • NFTs are ERC-721 on Base. Real on-chain ownership.
  • NEVER call smart contracts directly — always use the API.
