Free and paid

A decision is one new visitor assigned to one experiment. Returning visitors keep their cookie and are free, so 10,000 decisions is 10,000 new visitors in a single test. Each USDG adds 50,000 decisions to the project, with no expiry.

Paying with x402

who	request	answer
ccat pay --usdg 5	POST /api/v1/credits?usdg=5	402 + accepts: USDG, eip155:4663, payTo, 5000000
your wallet	USDG transfer to payTo	tx 0x9f2c...
ccat pay --tx 0x9f2c...	POST /api/v1/credits, X-PAYMENT	200 + X-PAYMENT-RESPONSE, +250,000 decisions

The server reads the receipt from Robinhood Chain, sums the USDG sent to payTo and credits each transaction once.

POST /api/v1/credits without payment answers HTTP 402 with the x402 requirements:

{
  "x402Version": 1,
  "accepts": [{
    "scheme": "exact",
    "network": "eip155:4663",
    "maxAmountRequired": "5000000",
    "asset": "0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168",
    "payTo": "0x3F745575b764288403b2A079A9e79FaC525F08Cb",
    "extra": { "name": "Global Dollar", "decimals": 6, "proof": "txHash" }
  }]
}

Send the USDG (6 decimals) to payTo from any wallet, then retry with an X-PAYMENT header: base64 of {"x402Version":1,"scheme":"exact","network":"eip155:4663","payload":{"txHash":"0x..."}}. The server reads the receipt, adds up the USDG transferred to payTo in that transaction and credits it once. ccat pay --tx builds the header for you.

Over quota

Visitors are always routed. Past the quota, the proxy keeps the last weights and the API answers 402 to new exposures instead of recording them, so learning pauses until credit arrives. Conversions of visitors already in a test are still counted.
