Pay per round.
Not per captcha.

The baseline is 1 credit per round, but we reserve the right to adjust the credits charged for a solve to reflect the current difficulty of hCaptcha’s challenges and our cost of solving them. Any change only affects solves you make after it takes effect, never credits you already hold. See our Terms of Service for the full policy.

Because captchas aren't uniform. A flat per-captcha price means you overpay for easy ones to subsidise the hard ones. Per-round billing is honest: customers with good residential proxies get fewer rounds and pay less. Incentives are aligned by design.

No. Buy a pack, use it whenever: next week, next month, next year. No clock, no expiry, no "use it or lose it." The credits you bought are yours until you spend them.

Credits have no daily cap. The only ceiling is your concurrency limit: 5, 25 or 50 solves at once depending on your spend, or 100 and 200 on the Professional and Enterprise plans. Inside that, burst as hard as you need. A plan gives you a set number of solves a day, and past them you can keep solving on credits.

A plan covers a set number of solves each day, and those solves don't use your credits. Once the day's solves are gone, the next ones come out of your credit balance as usual. You can hold a plan and a credit balance at the same time.

You carry on solving on credits. To stop spending credits instead, turn credit use off on your billing page; new solves are then refused until the 00:00 UTC reset.

Yes, from your billing page. A bigger plan starts straight away and you pay the difference for the rest of the period. A smaller one starts with your next period. If you cancel, the plan runs to the end of the period you've paid for.

If no token comes back, it costs you nothing. Credits are deducted only when a solve mints one, so a model that can’t crack the puzzle, a worker timeout, an expiry or a cancellation leaves your balance untouched — there is no refund step because there was no charge.

Yes — billing is per answered round, and a re-challenge is another answered round. There is no correctness discount hiding in the meter: if our model gets a round wrong and hCaptcha comes back with another, that round is billed like any other. What protects you is the other end: a solve that never mints a token costs zero, however many rounds it burned.

Yes, and you should. Customer-supplied residential proxies see noticeably fewer rounds per solve than shared pools. Send a "proxy" field in the POST /v1/solves body — either a full URL string (http://user:pass@host:port) or an object with host, port, scheme, username and password. Bringing your own makes your bill smaller. If you don’t supply a proxy, we route the solve through our own fallback proxy and bill per round up to a fixed maximum per solve — never more than that maximum, and less when a solve takes fewer rounds.

Credit packs: card or crypto, one-time per pack, no auto-renewal. When your balance runs low, you top up again. Plans: card, renewing each period until you cancel. Invoice / wire for accounts over $500/month, talk to us.

No. This page is what NoneCap charges to solve hCaptcha. hCaptcha itself sells plans to website owners: Basic is free, Pro is $139 a month ($99 a month billed yearly) and Enterprise is quoted. Those plans are compared in hCaptcha pricing explained.
