Pricing

Flat monthly plans plus per-request usage. Failed requests are never billed.

Each plan carries a flat monthly fee, with usage billed per request on top. Failed requests are not billed. Usage is charged at a fixed USD rate per request — the rate depends on the fetch method the API selects and the proxy class the target site needs, and it is lower on higher-tier plans.

Antibot and captcha challenges may require browser-based methods and premium proxies, so they can cost more than a clean standard request.

AI structured extraction adds a dynamic fee

Requests that use jsonSchema add an extraction fee on top of the per-request rate. It's metered per request and scales with the size of the page and the schema you request. The fee applies only when extraction actually runs — if a request falls back to the raw page, no extraction fee is charged.

Each search is billed at the browser standard rate — $2.00 per 1,000 searches on Starter, $1.00 per 1,000 on Growth.

Browser WebSocket (CDP)

Remote CDP WebSocket sessions are billed by resource usage instead of the per-request table above: bandwidth transferred and connection time are summed per session and charged when the session ends. These rates are the same on every plan, and each session is metered on its own — usage is not batched across sessions.
