api record

Paid tools use x402. tools/list is free. For tools/call, send the payment proof in the PAYMENT-SIGNATURE header; without it, the response carries the payment challenge and inputSchema.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ paid on base 30 days

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 77 other origins: the figure is the gateway's, not this listing's alone. How it is counted.

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly

_ what it can do 3 tools

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • browser_task 0.012 USDC paid never probed

    Loads one https page in a real headless browser and performs up to eight steps on it: click, fill, select, check, uncheck, wait, wait_for_selector. Returns a per-step log saying what was attempted and whether it succeeded, plus the final URL, title, visible text, links, form structure and an optional screenshot as a base64 PNG. Three limits are part of the product, not accidents. robots.txt is fetched and evaluated before the page is loaded, following RFC 9309 precedence, and a disallowed path is refused rather than fetched; an unreadable robots.txt counts as a refusal, not as permission. Login walls, captchas and paywalls are detected and the call is aborted instead of worked around. And a step cannot navigate: the only address loaded is the one in url, so this endpoint cannot be steered somewhere else by a step list. Nothing is charged when a call is refused for any of those reasons. Not suitable for pages that require a session, and not a crawler: one page per call.

  • form_dryrun reads 0.01 USDC paid never probed

    Loads a public https page, finds the requested form, fills your values into it in a real headless browser and reports what a submission would run into — without submitting. Each field is checked against what the page itself declares: whether it is required and empty, whether the value matches the field type for email, url, number, tel, date, time and color, and whether a select value is one of the offered options. Fields you named that the form does not have are reported, as are required fields you left out. The promise not to submit is structural, not a policy: the input schema has no place to put a selector or a click, and the only browser steps this endpoint generates are fill, select and check on fields that exist in the loaded form. It never clicks, and it never presses a key. One thing it cannot prevent and therefore states plainly: a page whose own script submits on input will do so regardless of who typed. What it cannot do is run the page own JavaScript validation — a site that checks values in script may still reject a value this endpoint calls plausible, and that limit is stated rather than papered over. robots.txt is honoured; login walls, captchas and paywalls end the call instead of being worked around, and a refused call is not charged.

  • ephemeral_browser reads 0.01 USDC paid never probed

    Creates a fresh browser context for one HTTPS page, obeys robots.txt, refuses login walls, CAPTCHAs and paywalls, renders JavaScript, returns a sanitized DOM and/or base64 PNG, and destroys the context after the request. There is no reusable cookie jar, session handle, login automation or navigation step list. The runtime ceiling is 60 seconds and the returned DOM is capped at 1 MiB.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

card completeness
70%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
