How paying works (x402)

Call a paid endpoint. It answers 402 Payment Required with the price and a Solana address.
Your x402 client signs a USDC transfer and repeats the request with it attached.
The data comes back and the payment settles. If the data is stale or the request fails, the payment is not settled.

pip install "x402[httpx,svm]"

from x402 import x402Client
from x402.http.clients import x402HttpxClient
from x402.mechanisms.svm.exact import ExactSvmScheme
from x402.mechanisms.svm.signers import KeypairSigner

client = x402Client()
client.register("solana:*", ExactSvmScheme(KeypairSigner(your_keypair)))
async with x402HttpxClient(client) as http:
    r = await http.get("https://crypto-regime-api.onrender.com/v1/regime")
    print(r.json())
