Web Tools and Web Tasks for AI agents. 100-credit MCP trial; API-key credits or x402.
Scored across 14 tools
Most tools target a distinct resource+action and the descriptions explicitly disambiguate the tricky pairs (web_crawl vs web_scrape_batch, web_map vs web_crawl). The main friction is the trio of near-identical status tools (web_crawl_status, web_batch_status, web_task_status) and the split between web_search_exa and web_task_start, which an agent must reason about but can resolve from descriptions.
All names share a clean `web_` snake_case prefix with a predictable resource_action shape (web_crawl_status, web_task_start, web_batch_status). Minor deviations: web_session_open/close invert to noun_verb order, and web_search_exa embeds a vendor name that breaks the verb_noun pattern.
14 tools is well-scoped for a scraping, crawling and browser-control server, with each tool covering a distinct verb or lifecycle step. No obvious filler or redundancy in the surface.
The core lifecycle (scrape, batch, crawl, map, search, session open/act/close, task start/status/cancel, feedback) is well covered and symmetrical for jobs. However, since every description stresses API keys and credits, there is a notable gap: no tool to check account balance or credit spend, and no way to list existing sessions, batches or tasks beyond a jobId the agent must already hold.
Runs actions against an open session and returns the resulting state. Actions: {navigate}, {click:{ref}}, {type:{ref,text,clear}}, {select:{ref,value}}, {press}, {scroll}, {wait}, {back}. The ref is the one controls gave you. It stops at the first failure and tells you where. $0.0005 (0.25 credit) per action, plus requested outputs and any outstanding browser time. API key and credits required. Reference for the oassis API: https://oassis.dev/openapi.json
Inputs: actions (required), sessionId (required), pdf, url, +12 more.
Checks a batch of scrapes: status, how many are done, and the results. Free for the owning account. Pass cancel: true to stop it.
Inputs: jobId (required), limit, cancel.
Follows a site's links and reads every page. Returns a jobId; poll it with web_crawl_status. API key and credits required; limit controls the maximum pages charged. Use web_map first if you only need the urls. Reference for the oassis API: https://oassis.dev/openapi.json
Inputs: url (required), json, wait, block, +13 more.
Checks a crawl: status, pages read, discovered and still queued, and the pages themselves. Free for the owning account. Pass cancel: true to stop it.
Inputs: jobId (required), limit, cancel.
Tell us an answer was good or bad. FREE. Use it when a result is wrong — empty markdown, a control map missing a button, data that does not match the page — with the url or the jobId so it can be reproduced. It is the only way we learn that we read a page badly: our logs cannot tell that apart from a page that is simply like that. Reference for the oassis API: https://oassis.dev/openapi.json
Inputs: verdict (required), url, route, comment, +1 more.
Every url of a site, fast and cheap: its sitemap plus, optionally, the links on the page. Use it BEFORE crawling, to see what is there and decide what is worth reading. 1 credit ($0.002) with includePage: false (no browser at all), 1.5 credits ($0.003) with the page. Reference for the oassis API: https://oassis.dev/openapi.json
Inputs: url (required), limit, search, includePage, +3 more.
Processes a page and returns every output you ask for at once: markdown, html, links, screenshot, PDF, accessibility tree, elements by selector, AI-structured data, and controls (what can be clicked). One call, and a partial failure does not void the rest. From 1 credit ($0.002) per output. A url pointing at a PDF, Word, Excel or CSV file is converted to markdown instead, with no browser, for $0.002. Reference for the oassis API: https://oassis.dev/openapi.json
Inputs: pdf, url, html, json, +11 more.
A batch OF SCRAPES: reads a list of urls YOU give it (2 to 50, from any sites) and returns a jobId. It discovers nothing on its own — for that use web_crawl. API key and credits required. Poll it with web_batch_status.
Inputs: urls (required), json, wait, block, +8 more.
Search the web with Exa's index: a query instead of a url, for when you do not know where to look. Returns title, url and a snippet per result. To read the pages, pass the urls to web_scrape_batch. The engine is named because the price is Exa's, passed through with no markup and read from its own payment challenge on every call — the quote is read at execution time and is not a guaranteed fixed price. API key and credits required over MCP.
Inputs: query (required), limit, since, domains, +2 more.
Closes the browser session and stops its time. HTTP equivalent: POST /web/v1/session/{id}/close. No additional close fee; outstanding browser time is settled when applicable. If you do not close it, it closes itself after a minute without use.
Inputs: sessionId (required).
Opens a browser session and returns the map of controls. Opening costs 2.5 credits plus the requested outputs; the first minute is included. Further started minutes cost 2 credits with an account key. Use web_act to interact and web_session_close when done. API key and credits required. Reference: https://oassis.dev/openapi.json
Inputs: url (required), pdf, json, wait, +10 more.
Stops a task using its owning API key, or its legacy access_token. No new operations start. Cancellation is free; unused account credit reservations are released. Cancelling a finished task changes nothing.
Inputs: id (required), access_token.
Starts a research task: a question answered by reading public pages, with sources, progress and cost. Requires an API key and credits. The maximum budget is reserved, actual execution cost is charged, and unused credits are released. Returns a task id: check it with web_task_status.
Inputs: task (required), mode, urls, limits.
Returns a task's status, progress, sources, limitations, result and billing. Only your own tasks.
Inputs: id (required), access_token.
