AgentPMT

Wallet-authenticated endpoints for autonomous AI agents.

The endpoint catalog below is auto-generated from the route schemas. It is the correct source for request/response field lists, but it does not spell out the cryptographic signing contracts an autonomous agent needs in order to call these endpoints end-to-end.

Choose a Tool Usage Path

Tool action calls use one endpoint, POST /api/external/tools/{productSlug}/actions/{actionSlug}/invoke, with two supported usage paths:

PathUse whenHow the call worksTradeoff
Credit based tool usage with AgentAddressThe agent needs persistent AgentAddress activity, reusable files/data, jobs, or repeated calls without paying each time.Buy credits through /api/external/credits/purchase, create a wallet session, sign EIP-191 runtime requests, then send wallet_address, session_nonce, request_id, signature, and nested parameters.More setup, but more AgentPMT features and tools are available, and the agent reuses a balance instead of settling a token payment on every action.
X402 payments for tool usageThe agent needs one eligible tool action and does not need persistent AgentAddress state for the call.Send action parameters directly, read the 402 challenge, sign one accepted payment requirement with EIP-712, then retry the exact same body with X-PAYMENT.Simpler for one-off calls, but it does not create stored credits or attach reusable file/data state to the AgentAddress.

Before building a client, read the companion guide for the path you are using:

Identity

POST /api/external/agentaddress

Create an anonymous AgentAddress to use instead of logging in. Pay with x402 crypto, no API keys or passwords needed.

Tool Calls

GET /api/external/tools

List available tools in your budget

List active, non-private products as external-invocable tools. Pagination contract (same on every response, including the search and category-filtered paths, including empty results): ``pagination.page``, ``pagination.page_size``, ``pagination.total_count``, ``pagination.total_pages``, ``pagination.has_more`` (boolean), ``pagination.next_page`` (int or null), plus ``pagination.default_page_size`` and ``pagination.max_page_size`` so agents discover the bounds from the response itself. Default ``page_size`` is 100; caller may request up to 1000. Iterate by bumping ``?page=`` while ``has_more`` is true (or equivalently until ``next_page`` is ``null``). The access gate is ``status: "active"`` AND ``is_private != true`` -- **no ``enable_external_calls`` flag is consulted**. Access to actually invoke any tool is enforced at the invoke endpoint by credit balance and budget, not by list membership.

Examples

Get a direct x402 challenge

Send the action parameters directly. This first request returns 402 Payment Required when payment is needed.

curl -i -s -X POST "https://www.agentpmt.com/api/external/tools/<productSlug>/actions/<actionSlug>/invoke" \
  -H "Content-Type: application/json" \
  -d '{
  "your_param": "value"
}'

Retry direct x402 payment

Retry the exact same action parameters with X-PAYMENT. A successful paid tool call returns the tool result.

curl -i -s -X POST "https://www.agentpmt.com/api/external/tools/<productSlug>/actions/<actionSlug>/invoke" \
  -H "X-PAYMENT: <base64-x402-payment-envelope>" \
  -H "Content-Type: application/json" \
  -d '{
  "your_param": "value"
}'

Invoke with AgentPMT credits

Credit calls send wallet/session/signature fields and place action parameters inside parameters. Prefer signing the canonical path without /api; the server accepts bounded same-action path variants for external-agent compatibility.

curl -i -s -X POST "https://www.agentpmt.com/api/external/tools/<productSlug>/actions/<actionSlug>/invoke" \
  -H "Content-Type: application/json" \
  -d '{
  "wallet_address": "0xYOUR_WALLET",
  "session_nonce": "<session_nonce>",
  "request_id": "<request_id>",
  "signature": "<signature>",
  "parameters": {
    "your_param": "value"
  }
}'

Message to sign for AgentPMT credits

Sign this EIP-191 message before sending the signed-credit tool request.
