Pricing

From $0.50 per thousand. Successes only.

No card, no minimum, no invoice. Top up a balance in crypto and it draws down per solve — a failure costs nothing and is refunded automatically.

USD / 1k is metered: charged per successful solve, drawn from your balance, failures refunded. Thread-day is the subscription rate — unlimited solves of that type per concurrent thread, priced 40% under the metered equivalent at 8,000 solves a thread-day. A dash means the type is metered only.

What you are charged

Charged on return, never on send.

A provisional hold is placed when a solve starts and released the moment it fails. Only a response with errorId: 0 results in a debit, and the exact amount comes back in the cost field of that response.

Failures are free

A blocked IP, an unsolvable challenge, a timeout — none of them are billed. You pay for tokens you actually received.

Test keys are free

Every account gets a test key that solves a synthetic challenge. Run it in CI on every commit without touching your balance.

Credit does not expire

What you top up stays available. There is no monthly drawdown and no dormancy fee.

Questions

Common questions

Do I pay for failed solves?

No. Only a successful solve is charged. If a call returns a non-zero errorId, nothing leaves your balance and any provisional hold is released immediately.

Is there a minimum?

No. You top up a balance and it is drawn down per successful solve. There is no minimum spend and no expiry on credit.

What is the difference between pay-per-1k and a subscription?

Pay-per-1k draws down a balance for each successful solve, so you pay for exactly what you use. A subscription buys unlimited solves of chosen types for a fixed period, priced per concurrent thread rather than per solve — it is cheaper once a thread is busy most of the day, and it makes the bill predictable. You can hold both at once: a subscription covers the types it names, and anything outside it falls back to the balance.

Which types can be bought as a subscription?

TLS API, reCAPTCHA v2, reCAPTCHA v3, reCAPTCHA Mobile, FunCaptcha, DataDome, Imperva, Cloudflare Turnstile, GeeTest, Hunt Captcha, Cloudflare Clearance, Akamai, AWS WAF, PerimeterX. Every public type, each priced against its own measured throughput.

How do I pay?

Crypto only — 13 currencies across 25 asset and network combinations: USDT on TRC20, ERC20, BEP20, Solana, Polygon or TON, USDC on Base, BEP20, Solana, Polygon or ERC20, and BTC, ETH, BNB, SOL, TRX, POL, LTC, DOGE, DAI, DOGS and XMR on their own chains. No card and no invoice.

Do I need my own proxy?

For most types, yes: the solve has to originate from the same address you will use the result on, so you supply the proxy. The exceptions are Cloudflare Turnstile, which takes no proxy field at all, and ReCaptchaMobileDirect, which mints from our own address — both run proxyless by design.

Is there a free trial?

Yes: 100 free solves once you confirm your email, on any type — real tokens from the live solvers, one trial per person. Your first top-up also gets a bonus of +50% up to $25, added automatically. Every account also gets a test key that returns a well-formed response without touching your balance, so you can build and run the integration in CI for free.

Build it free. No card.

The test key exercises the real code path across 13 types without touching your balance. Top up when you want live tokens.
