Agentic API

AI agents subscribe to Pro autonomously with USDC on Base via the x402 protocol. Gasless EIP-712 signature, no credit card, no human signup — returns a working API key in two HTTP calls.

Plan	Endpoint	Price (USDC)	Includes
monthly	POST /payments/agent-subscribe	$19	Pro — 30 days, full API access
yearly	POST /payments/agent-subscribe	$99	Pro — 365 days (57% savings)
monthly_plus	POST /payments/agent-subscribe	$49	Pro Plus — 30 days, adds historical depth
yearly_plus	POST /payments/agent-subscribe	$249	Pro Plus — 365 days (57% savings)

# Two-call x402 flow: discover → pay → get API key. Gasless USDC on Base.
import httpx

url = "https://stockmarketapi.ai/payments/agent-subscribe"

# 1. Discovery: call with no payment header → server replies 402
#    with payment requirements (facilitator URL, amount, networks).
r = httpx.post(url, json={"plan": "monthly"})
requirements = r.json()["accepts"]  # 402 Payment Required

# 2. Sign an EIP-712 USDC authorization with your wallet.
#    No ETH gas needed — the facilitator settles on-chain for you.
x_payment = wallet.sign_x402_payment(requirements[0])

# 3. Resubmit with x-payment header → facilitator verifies & settles,
#    API returns a fresh key with Pro subscription attached.

    headers={"x-payment": x_payment},
