Connect Hermes to AntSeed

Set up AntSeed as the model backend for a Hermes agent. Hermes is the agent framework (successor to OpenClaw) and AntSeed is a P2P network of AI service providers. The buyer proxy runs next to Hermes and routes its LLM calls through the network.

This skill replaces openclaw-antseed, which is stale.

Picture

Hermes agent  →  127.0.0.1:8377  →  AntSeed P2P  →  Provider peer  →  Upstream API
                 (buyer proxy)      (on-chain payment channels)

• Buyer proxy discovers providers via DHT, opens a payment channel per seller, signs per-request vouchers.
• Exposes an OpenAI-compatible /v1/* endpoint — that's what Hermes points at as OPENAI_BASE_URL.
• The model ID Hermes passes is the AntSeed service ID (e.g. minimax-m2.7), not an OpenAI model name.

The buyer proxy and Hermes can run on the same machine (laptop, VPS, cloud box — anywhere). The only requirement is that Hermes can reach 127.0.0.1:8377.

Before you start

Ask the user anything you don't already have:

• Where Hermes is running — same machine you're acting on, or a remote host you reach over SSH. Most setup steps are identical; remote hosts just need everything prefixed with ssh user@host.
• Chain — base-mainnet for real funds, base-sepolia for testnet. Default to base-mainnet unless the user says otherwise.

Install the CLI

npm install -g @antseed/cli
antseed --version

Requires Node.js 20+. Latest version: npm view @antseed/cli version. A global npm install can take 1–3 minutes — use a long timeout.

Chain configuration

Custom ~/.antseed/config.json is optional. antseed buyer start works without one and will use built-in defaults.

Create the file only if you want advanced settings such as pricing caps or a non-default chain:

{
  "network": {},
  "buyer": {
    "minPeerReputation": 0,
    "maxPricing": {
      "defaults": {
        "inputUsdPerMillion": 100,
        "outputUsdPerMillion": 100
      }
    }
  },
  "payments": {
    "preferredMethod": "crypto",
    "crypto": {
      "chainId": "base-mainnet"
    }
  }
}

Do not hardcode contract addresses. @antseed/node resolves Deposits, Channels, USDC, and the RPC URL from chainId via its built-in chain-config presets. Hardcoded addresses drift when contracts redeploy; the preset is the source of truth.

To switch chains later, edit only chainId (base-mainnet ↔ base-sepolia) and restart the buyer.

Identity and the buyer wallet

The buyer needs an EVM identity — a 32-byte secp256k1 private key supplied via the ANTSEED_IDENTITY_HEX env var (64 hex chars, optional 0x prefix), or already present in ~/.antseed/identity.key.

The EVM address derived from that key is your buyer wallet. It needs:

• USDC on the target chain — used as payment channel reserves
• Native token (ETH on Base) — used for gas on deposit, operator signing, and withdraw

Never move identity.key off the host that runs the buyer. The hot wallet stays put. Funding happens via the payments portal running on that host (see next section), not by exporting the key to a wallet app on another machine.

Check balance any time:

antseed buyer balance

Running the buyer proxy

Foreground, for a laptop or a quick test:

antseed buyer start

Advanced: if Hermes must use a non-default proxy port:

antseed buyer start --port 5005

Persistent (Linux, systemd):

sudo tee /etc/systemd/system/antseed-buyer.service > /dev/null <<EOF
[Unit]
Description=AntSeed Buyer Proxy
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
User=$USER
Environment=ANTSEED_IDENTITY_HEX=<64-hex-no-0x>
ExecStart=/usr/bin/env antseed buyer start
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable --now antseed-buyer

The service user must own the ~/.antseed/ directory that holds config.json and identity.key.

The buyer startup log prints the Deposits/Channels addresses and RPC URL it bound to — glance at those to confirm it's on the chain you expected.

Funding via the payments portal

antseed payments starts a local web UI bound to 127.0.0.1:3118, protected by a random bearer token printed once at startup. Use it to deposit USDC, view channel state, and withdraw.

antseed payments
# Payments portal running at http://127.0.0.1:3118?token=<hex>

Open the printed URL in a browser with the ?token=... query string intact — the frontend reads the token from window.location.search exactly once and caches it. If you land on / without the token, every API call returns 401.

The token rotates on every portal restart. If you've restarted the portal and the browser starts returning 401s, tell the user to close the tab fully and reopen with the new URL — a refresh alone won't drop the cached token.

From the portal, the user connects an external wallet (MetaMask, Coinbase Wallet, etc.) and signs the deposit transaction there. USDC flows from the user's cold wallet into the Deposits contract, credited to the buyer address.

When Hermes runs on a remote host

If the buyer runs on a remote box, 127.0.0.1:3118 isn't reachable from the user's browser directly. Start the portal on the remote host detached, then SSH-forward the port to the user's laptop.

Start the portal remotely so it survives the SSH call returning:

ssh user@host "nohup antseed payments > /tmp/antseed-payments.log 2>&1 </dev/null & disown"
ssh user@host "cat /tmp/antseed-payments.log"   # read back the bearer token

A bare ssh user@host "antseed payments &" will die on disconnect — always nohup + disown + redirect stdio.

Then open a local forward on the user's laptop:

ssh -N -L 127.0.0.1:3118:127.0.0.1:3118 user@host

Bind the left-hand side explicitly to 127.0.0.1: — omitting the host lets OpenSSH pick IPv6-only, which many browsers then fail to reach.

Give the user http://127.0.0.1:3118/?token=<hex> (the URL from the portal log). The browser hits the local forward, which reaches the remote portal.

If ssh -L fails with channel 1: open failed: administratively prohibited, the remote sshd has AllowTcpForwarding no. Enable it in /etc/ssh/sshd_config (or a drop-in under /etc/ssh/sshd_config.d/), run sudo sshd -t to validate, then sudo systemctl reload sshd. Existing SSH sessions are not dropped by the reload.

Pick a peer

The buyer proxy does not auto-select peers. Every request is rejected with no_peer_pinned until a peer is pinned — you must pick one explicitly.

List the network, find a peer that serves the model you want, and pin it:

antseed network browse                              # table of peers and their services
antseed network peer <peerId>                       # full details for one peer
antseed buyer connection set --peer <peerId>        # pin it for this session

Alternatively, pass x-antseed-pin-peer: <peerId> as a per-request header if the caller can inject headers.

For persistent systemd deployments, put --peer <peerId> in the ExecStart= line instead — it survives restarts and avoids a stale state file.

Wiring Hermes to the buyer proxy

Register AntSeed as a custom provider in ~/.hermes/config.yaml and point model.default at an AntSeed service ID. Hermes reads this file at startup; nothing needs to be in .env for the AntSeed route itself.

model:
  default: minimax-m2.7
  provider: antseed

custom_providers:
  - name: antseed
    base_url: http://127.0.0.1:8377/v1
    api_key: antseed-p2p
    api_mode: chat_completions
    models:
      - deepseek-v3.1
      - minimax-m2.7
      - kimi-k2.5
      - glm-5.1
      - qwen3-coder-next

Notes:

• base_url must match the buyer proxy port. Default is 8377; if you started the buyer with --port 5005, use http://127.0.0.1:5005/v1 here instead.
• api_key is required by Hermes' OpenAI client but ignored by the buyer proxy — any non-empty string works. antseed-p2p is the convention.
• api_mode: chat_completions is required — the buyer proxy speaks OpenAI chat-completions, not the Responses API.
• models is the menu Hermes exposes to the user; only IDs listed here can be selected. Mirror it against antseed network browse (or curl -s http://127.0.0.1:8377/v1/models) so you don't advertise models no peer serves.
• model.default is the one Hermes uses when no explicit model is passed; model.provider: antseed pins it to this custom provider.

Swapping the routed model

If you switch to a model the currently-pinned peer doesn't serve, re-pin to a peer that does (antseed network browse → antseed buyer connection set --peer <peerId>) before the next request. Then edit model.default (and the models list if needed) and restart the Hermes systemd unit — the buyer proxy stays up, no CLI change, no contract call:

sudo systemctl restart hermes
sudo journalctl -u hermes --no-pager -n 20

On a remote host, the same two commands prefixed with ssh user@host.

Sanity check

antseed buyer balance                            # funds are present
curl -s http://127.0.0.1:8377/v1/models | head   # buyer proxy is answering

Then send a prompt through Hermes and watch the buyer log — you should see a channel open on the first request, then per-request voucher signing.
