AgentPMT AgentAddress + Paid Marketplace Flow

Use this skill when an autonomous agent must:

• create or load an EVM wallet,
• buy AgentPMT credits via x402,
• and spend credits by invoking paid marketplace tools and workflows.

Always call production external endpoints at https://www.agentpmt.com/api/external/....

External Endpoints

Wallet and credits:

• POST /api/external/agentaddress
• POST /api/external/credits/purchase
• POST /api/external/auth/session
• POST /api/external/credits/balance

Marketplace tools:

• GET /api/external/tools
• POST /api/external/tools/{productId}/invoke

Marketplace workflows:

• GET /api/external/workflows
• POST /api/external/workflows/{workflowId}/fetch
• POST /api/external/workflows/{workflowId}/start
• POST /api/external/workflows/active
• POST /api/external/workflows/{workflowId}/end

x402 Credit Purchase Contract

Credit pricing and validation:

• 100 credits = 1 USD
• USDC base units required: credits * 10000
• Credits must be bought in 500-credit increments

Request body:

{
  "wallet_address": "0x...",
  "credits": 500,
  "payment_method": "x402"
}

Two-step handshake:

1. First call returns 402 + PAYMENT-REQUIRED header (base64 JSON).
2. Decode header and sign EIP-3009 TransferWithAuthorization.
3. Retry same endpoint with PAYMENT-SIGNATURE header (base64 JSON payload).

Expected signing inputs from PAYMENT-REQUIRED.accepts[0]:

• network
• amount
• asset
• payTo
• optional extra.name and extra.version

Signature Contract (EIP-191)

All signed external actions use this exact message template:

agentpmt-external
wallet:{wallet_lowercased}
session:{session_nonce}
request:{request_id}
action:{action}
product:{product_or_dash}
payload:{payload_hash}

Canonical payload hashing:

• canonical_json = json.dumps(payload, sort_keys=True, separators=(",", ":"))
• payload_hash = sha256(canonical_json).hexdigest()
