Pay per request (x402)

Agents can pay for API calls and packs in USDC with x402, no key or account needed.

PokerData accepts x402 payments, so an agent with a USDC wallet can call the API or buy a pack without an API key or an account.

How it works

Call a paid endpoint with no Authorization header. The answer is 402 Payment Required with a PAYMENT-REQUIRED header (base64 JSON) naming the price, network, token and receiving address.
Sign the USDC payment and repeat the request with a PAYMENT-SIGNATURE header. x402 client libraries such as @x402/fetch do both steps for you.
You get the normal response plus a PAYMENT-RESPONSE header with the settlement. A call that fails (any status 400 or above) is not charged.

Endpoint	Price (USDC)
`GET /api/v1/ranges/…` (paths that need a key)	$0.01 per call
`GET /api/v1/postflop/node`	$0.01 per call
`GET /api/x402/packs/{id}`	$50 per pack

GET /api/x402/packs/{id} takes a preflop pack id or a postflop pack id. After payment it returns a download link for that one archive:

{
  "pack": "nlh-mtt-8max-20bb",
  "url": "https://…",
  "expiresInHours": 12
}

The link expires after 12 hours, and the purchase is not tied to an account, so download the file once you have the link.
