  • crawler_block_testTest what a domain actually serves AI crawlers

    What the domain's CDN really does, as opposed to what its robots.txt says. Sends each AI crawler's real user-agent at the homepage and compares the response against a browser: a site can allow GPTBot in robots.txt and still have its CDN answer it a 403, and robots.txt cannot tell you that. Verdicts per crawler: ok, blocked, throttled (429, which is "too fast" and not "not you"), degraded (a 200 with a fraction of the bytes, the shape of a JS-gated page), or error. When `measurable` is false the site refused the control request too and there is no verdict to give. Live probe, ~6 requests. Free.…

  • preflightPreflight a domain

    What a domain publishes for AI agents before you touch it: ai-catalog.json (ARD), llms.txt, agents.md, and its robots.txt directives for AI bots (GPTBot, ClaudeBot, Google-Extended…). Includes a visibility receipt: surface-by-surface state, the words that would find the domain in search (or the honest fact that none would), what is missing and where to publish it. Served from the Desvela ARD index when fresh (<7 days), live-checked otherwise. Free.

  • searchSearch the agent-readable web

    Natural-language search over what Desvela has indexed: agents, MCP servers, registries — the same index as POST /search. Returns catalog entries per the ARD spec. When nothing matches, returns referrals (other ARD-conformant registries you can query the same way) and listing (how a domain gets into this index: publish ai-catalog.json, then preflight it), instead of an empty answer.

  • watchWatch a domain for agent-surface changes

    Subscribe to a domain: get a signed webhook (X-Desvela-Signature, HMAC-SHA256) when what it publishes for AI agents changes — ai-catalog.json entries added/changed/gone, llms.txt or agents.md edited or removed, robots.txt AI-bot directives changed. Checked weekly against the Desvela ARD index. Returns a manage_token (GET/DELETE https://registry.desvela.dev/watch/{id}) and the signing secret — store both.
