Agent readiness · Product analytics

8 of 14 measurable points under formula 9.2, measured on 2026-08-12. 15 checks exist; each is one HTTP request with a published rule, so every sentence below can be rerun and argued with. 2 of them could not be measured from where we ask, and those are left out of the denominator rather than counted as failures.
A · Discovery
- PASSAnswers an agent user-agentAnswered 200 to LetAgentsIn/1.0 (+https://letagentsin.com/methodology)
- PASSllms.txt publishedllms.txt and llms-full.txt present at https://usefathom.com/llms.txt and https://usefathom.com/llms-full.txt, and the 12 links we sampled across both files all answer
- PASSDocs readable without JavaScript6,630 characters of text without JS, on https://usefathom.com/docs/account/add-delete rather than on https://usefathom.com/docs
- PASSOn-demand agents not blockedNo on-demand agent is blocked
- N/APaths robots.txt points at answerrobots.txt names no concrete path, only patterns or nothing, so there is no claim to check
- PASSNo punishing crawl delayNo Crawl-delay applies to the agents we check
B · Agent entry
- FAILAgent entry pointNone of the 9 known agent entry paths returns a file rather than your page shell
- FAILOAuth dynamic client registrationNo OAuth metadata on any of the 9 hosts probed, including the usual auth and api subdomains
- FAILMCP surfaceNo MCP surface: nothing answered at mcp.usefathom.com, mcp.usefathom.com/mcp, mcp.usefathom.com/v1/mcp, api.usefathom.com/mcp, /mcp or /api/mcp, and no file mentions MCP
C · Registration
- UNMEASUREDNo CAPTCHA in the signup HTMLUnmeasurable: the signup form at https://app.usefathom.com/register is not in the server HTML, so its gates are not eitherServer-render the form, or tell us the endpoint it posts to, and the gates become visible to us and to an agent.
- FAILSignup reachable without a browserhttps://app.usefathom.com/register is reachable, but its form needs JavaScript
D · Provisioning
- PARTProgrammatic key provisioning1 of 7 provisioning phrases across the 4 documents we read: "account api"
- PASSFree tier or no-card trial stated in textFree tier or no-card signals at https://usefathom.com/pricing: "Free trial"
E · Integration
- UNMEASUREDTyped SDK on the registryUnmeasurable: we could not identify the package a developer installs to use you, from your site, your docs or a registry searchName your package once in your docs, or link it from your repository, and we stop guessing. If your product is not something a developer installs, this check does not apply to you: unmeasured is out of the score and out of the denominator, so it costs you nothing.
- PASSMachine-readable API descriptionOpenAPI at https://usefathom.com/api/openapi.json
Tell me when this changes
The failures here are the kind nobody notices. An edge rule that starts refusing agents changes nothing a person sees in a browser, so the first sign is usually an integration that quietly stopped working. We rescan weekly and write only when a verdict moves.
This page is the newest scan we hold for usefathom.com and changes when we rescan. It is not a judgement of the product: we measure whether an unattended run can get through, not whether the thing is any good. The whole corpus is published as JSON and CSV.
