Supports crypto payment invoices on the Polygon network for purchasing paid access tiers, allowing agents to pay with USDT/USDC and unlock trading signals/data.
A minimal, runnable example showing an AI agent discovering, paying for, and unlocking live trading data over MCP using the x402 machine-payment pattern — no human, no dashboard, no checkout form.
This talks to the real, live AlphaBotPro MCP server. Nothing here is a mock.
initialize — standard MCP JSON-RPC handshake
tools/list — discover the available tools
get_catalog — a public tool: prices and sample payloads, no auth
get_signals without a key — a clean, structured payment_required
error (the x402 pattern) instead of a silent failure
purchase_access — request a crypto invoice (USDT/USDC on TRON,
Polygon or Base) for a paid tier
check_payment — poll until the invoice settles, then receive a
scoped API key
get_signals again, now authenticated

node example.mjsNo dependencies, no API key required to run steps 1–5 (only step 6/7 need a
real payment to complete — the script prints the payment instructions and
exits there unless you pass --pay, which is left as a manual step since it
requires a funded wallet).

Most "AI-ready" APIs still assume a human signs up, enters a card number, and pastes a key into a config file. That breaks the moment the buyer is an autonomous agent. This server lets an agent discover the price, pay in stablecoins, and start pulling data — all inside one continuous session.
