webcap tools (20)

write = sends, deletes, buys or posts
  • webcap_agent_funnelFree

    Free agent-income funnel: reach, 402 challenges, trial claims, paid calls, distinct paying wallets and funded watches. Aggregate only; use to see real usage.

  • webcap_analyzeFree

    PAID ($0.01): AI analysis of one URL. Pick the task that matches the question you are answering.

  • webcap_auditFree

    PAID ($0.002): SEO basics plus link and Open Graph health for one URL in a single call. Returns issues with severity, not just raw tags.

  • webcap_captureFree

    PAID ($0.001 image/PDF, $0.005 video): turn a URL into a persistent public artifact. png/jpeg/pdf are a screenshot or PDF and include free OG metadata; mp4/webm scroll-record the page as WebM/VP8 (mp4 is a legacy alias). Settles gasless USDC over x402 — but an unpaid call runs free while the rolling per-IP allowance lasts, so just call it.

  • webcap_extractFree

    PAID ($0.01, one payment covers a batch of up to 50 URLs): structured content as JSON — title, headings, paragraphs, links, images, document-order markdown. Provide exactly one of "url" (a single page) or "urls" (a batch); "url" is shorthand for a one-item "urls".

  • webcap_feedbackFree

    Free feedback into webcap: message (8-4000 chars) plus optional category and the endpoint you were using. No account, rate-limited per client (60/hr). Also open to humans at GET /feedback.

  • webcap_healthFree

    Free liveness + chain info.

  • webcap_map_liteFree

    PAID ($0.002): discover a site's URLs from its sitemap and robots.txt plus a 1-hop same-host crawl, and return them as a JSON list. Cheaper than crawling each page with webcap_extract.

  • webcap_ogFree

    Free Open Graph metadata for a URL: title, description, image, icon. No payment.

  • webcap_previewFree

    Free bounded preview of a page: title, description, headings, links, word count and a truncated markdown slice. Use it to peek before the full extract. Rate-limited per IP. This is a teaser, not the product: the real products are free too inside the rolling per-IP allowance.

  • webcap_quick_thumbnailFree

    Free no-wallet JPEG thumbnail (3/day per IP). The full trials need a wallet signature.

  • webcap_serviceFree

    Free machine catalog: every paid endpoint with its exact price, the network, USDC asset, payTo, facilitator and the how-to-pay flow. Call this first to learn what webcap can do and what it costs.

  • webcap_service_catalogFree

    Free service catalog (no payment): every paid endpoint with its exact price in USDC, the settlement network, USDC asset, payTo address, facilitator and the step-by-step x402 how-to-pay flow, plus the free allowance this caller has left. Call this first to learn what webcap sells and what it costs.

  • webcap_trial_claim_analyzeFree

    FREE (one per wallet): one real deterministic visual analysis, no payment. Model-backed analysis stays paid.

  • webcap_trial_claim_auditFree

    FREE (one per wallet): one real SEO + link/OG audit, no payment. Claim it before buying webcap_audit.

  • webcap_trial_claim_captureFree

    FREE (one per wallet): a real full PNG screenshot plus its public artifact URL, no payment. Claim it before buying webcap_capture.

  • webcap_trial_claim_extractFree

    FREE (one per wallet): one real single-URL structured extraction, no payment. Claim it before buying webcap_extract.

  • webcap_trial_claim_map_liteFree

    FREE (one per wallet): one real site-map run capped at 10 URLs, no payment.

  • webcap_trial_statusFree

    Free per-wallet trial menu: which endpoints a wallet already claimed, which it can still claim, the exact claim recipe, and the priced paid catalog with how to pay (x402) once the free calls are used.

  • webcap_videoFree

    PAID ($0.005): scroll-capture a page as an MP4/WebM video artifact.

Why webcap?

Features

Bearer-token rail (no signing key)

The same products are buyable with an API key: POST /v1/register ({"address"} → {apiKey}), fund with a plain USDC transfer via POST /v1/invoice, then send Authorization: Bearer to POST /v1/extract, POST /v1/audit, POST /v1/map-lite, POST /v1/video, POST /v1/analyze, or POST /v1/analyze/batch. Every call costs 1 credit, refunded whenever the call does not return 200; an empty balance answers 402 with a 1-credit top-up invoice. Watches fund the same way: POST /v1/watches/{id}/topup {"runs": 100} (capture pack 10 credits, extract pack 100). Full spec: GET /openapi.json (tags: accounts).

Free endpoints (no payment)

Quick start

Use as an MCP server (agent runtimes)

webcap ships an MCP server, so any MCP host (Claude Desktop, Cursor, agent frameworks) can call it as a tool. Two ways to wire it: a remote endpoint (no install at all) or the stdio server from a checkout.

The remote endpoint is the cheapest path for an agent — nothing to install, no package registry, no account:

{
  "mcpServers": {
    "webcap": { "url": "https://webcap.shoutsid.fyi/mcp" }
  }
}

Shortened. The full README is on GitHub.
