Reliable web access for AI agents: smart HTTP, rotating proxies, and full-browser rendering.

Список инструментов сервера (4)

Технические названия из tools/list. Нужны только разработчикам.

foura_single	Send one HTTP request and return the response. Use it for static pages, JSON APIs, and server-rendered HTML, with your own headers, body and cookies. Set browser, os, or version when a target refuses the default Chrome. Pass a proxy id returned by foura_proxy to leave from that same exit. validate decides what counts as success, so a response it rejects comes back as a failure instead of as content; the timeouts nest, with timeout_ms bounding the whole request and the connect, accept and server_response ones bounding stages inside it. Switch to foura_proxy when the response is blocked or the exit country matters, and to foura_browser when the page needs JavaScript. One FourA API key authenticates every call, the result reports the credits it spent, and a refusal by your own plan arrives as a plan_limit_ code with retryAfter rather than as a block by the target.
foura_proxy	Route an HTTP request through rotating proxies, retrying on another exit until one delivers. Use it when foura_single is blocked, and whenever the exit itself matters: this is the only tool that takes a strict exit-country allowlist (exitCountries, which never falls back to another country), presents a named browser family per attempt, excludes exits you already know are dead (ignoreProxies), and may escalate to a premium exit (exitClass, an allowance rather than an instruction). maxTries bounds how many exits are tried and timeout_ms bounds the whole rotation, so a short timeout can end it before maxTries is reached; protected targets often need 25 to 30. validate decides what counts as delivered, and an attempt it rejects is retried on the next exit. The response returns the id of the exit that succeeded: pass that returned id to foura_single.proxy or foura_browser.proxy to send the next request from the same exit. A failed rotation returns attemptReport, which separates exits that never answered from exits a bot check refused from pages your own rule threw away. Use foura_browser when the page needs JavaScript. Rotation costs several times a single request. One FourA API key authenticates every call, the result reports the credits it spent, and a refusal by your own plan arrives as a plan_limit_ code with retryAfter rather than as a block by the target.
foura_browser	Load a public URL in a full browser session. JavaScript runs, the DOM renders, and cookies come back with the response. Use it for single-page apps, lazy-loaded content, or supported browser challenges. You can set your own headers, cookies and userAgent, and checkStatus or checkText turn a navigation that rendered the wrong page into a failure instead of returning it as content. For a protected page, call foura_proxy first and pass its returned proxy ID here to reuse that same exit, instead of starting a new selection here; with no proxy the session leaves from one fixed address. Set unblocker:false when you want the page exactly as it loads, challenge included. It is the most expensive of the four tools and the slowest, so prefer foura_single or foura_proxy whenever the content is already in the HTML. One FourA API key authenticates every call, the result reports the credits it spent, and a refusal by your own plan arrives as a plan_limit_ code, including plan_limit_browser_daily when the daily browser allowance is spent.
foura_auto	Give it a public URL and get the content back. Use it when only the content matters and not how it is fetched: it escalates from a direct request to a rotating proxy to a full browser only as far as the target forces, and returns the session that worked so the next call can replay it. On protected targets, or whenever HTTP 200 may still be a challenge or an incomplete page, pass validate.data.accept with text unique to the real content; auto makes bounded attempts and returns either validated content or a failure, and cannot guarantee a match. It owns its own retry settings, so there is no maxTries here, and timeout_ms is the budget for every attempt together rather than for one. What it cannot do is the reason to reach for another tool: a strict exit country, a pinned exit and a premium exit live on foura_proxy (auto can only avoid exits, through ignoreProxies); choosing which browser is presented to the target lives on foura_single and foura_proxy; a scripted browser session lives on foura_browser. A request that names any of those belongs there rather than here. One FourA API key authenticates every call, the result reports the credits it spent, which is the sum of the attempts it made, and a refusal by your own plan arrives as a plan_limit_ code with retryAfter rather than as a block by the target.
