Conversation
The site already served llms.txt, per-page markdown mirrors, canonicals, a sitemap and an RSS feed, but an agent arriving cold had no way to find the security contact, the HTTP APIs behind the product, or the MCP server, and nothing it fetched was readable cross-origin. - /.well-known/security.txt (RFC 9116), /.well-known/api-catalog (RFC 9727, linking both published OpenAPI specs to their docs pages), and /.well-known/mcp.json describing the stdio `agent-relay mcp` server. The App Router skips dot-prefixed directories, so these live under app/well-known/ and next.config rewrites the canonical paths onto them; the internal path carries X-Robots-Tag: noindex and a robots.txt disallow. - CORS (Access-Control-Allow-Origin: *) on every machine-readable endpoint — llms.txt, the markdown mirrors, feed.xml, sitemap.xml, robots.txt and the well-known documents — plus X-Content-Type-Options: nosniff site-wide. - Site-wide Organization / WebSite / SoftwareApplication JSON-LD in the root layout, cross-referenced by @id so any single page resolves its publisher. - <link rel="alternate"> for llms.txt, llms-full.txt and the feed on every page, so the plain-text mirrors are discoverable from any entry point. - robots.txt names the AI crawlers and agent fetchers that read their own user-agent (Perplexity, Google-Extended, Applebot, Meta, Amazon, CCBot, Mistral, Cohere and others) alongside the OpenAI and Anthropic entries.

There was a problem hiding this comment.
When an API-catalog consumer uses this anchor as the API base, it is directed to api.agentrelay.com, while the linked Relaycast documentation identifies https://cast.agentrelay.com/v1 as the hosted production endpoint and uses it in request examples. This makes the new machine-readable catalog inconsistent with its own service documentation and can cause generated clients or agents to target the wrong host.

There was a problem hiding this comment.
When security tooling or a researcher follows the Policy field, this sends them to the general Terms of Service, which contains no vulnerability-reporting or disclosure policy. Since Policy specifically advertises where the site's security policy can be found, publishing this unrelated URL makes the new discovery document misleading; omit the field until a real policy exists or point it to an actual security-policy page.

Apply the /well-known/ exclusion to named crawlers.
AI_CRAWLERS.map(...) emits a separate, more-specific robots group for each named crawler. Those crawlers use their own Allow: / group and do not fall back to the wildcard group, so Line [57] does not block /well-known/ for named crawlers. The Robots Exclusion Protocol selects the matching specific group, and Next supports grouping multiple user agents in one rule. (datatracker.ietf.org)
If /well-known/ is an internal rewrite target that no crawler should request, add the same disallow to the named groups. Group AI_CRAWLERS into one rule to keep the policy consistent.

- userAgent,
- allow: ['/'],
- })),

RFC 9116 Expires field less than one year in the future exact wording
💡 Result:
The exact wording in RFC 9116 regarding the Expires field is: "It is RECOMMENDED that the value of this field be less than a year into the future to avoid staleness." [1][2][3] This recommendation is found in Section 2.5.5 of the document [1][2]. While some secondary sources describe this requirement as mandatory [4][5], the official RFC explicitly uses the term "RECOMMENDED" [1][2][3].

Keep Expires less than one year ahead.
For 2028-02-29T00:00:00Z, setUTCFullYear(... + 1) produces 2029-03-01T00:00:00Z, which is 366 days ahead. Use a fixed duration such as 364 days and add a leap-day test.

api.agentrelay.com does not exist. It was in the api-catalog anchors added by
the previous commit, and in two marketing snippets that predate it.
Replaced with the hosts the v8 docs name as authoritative:
- Relaycast -> cast.agentrelay.com/v1, per the base-URL table in
content/docs/relaycast-api.mdx. content/docs/loop/sources.mdx still pointed
at api.relaycast.dev, which only survives in the archived 7.1.1 docs and on
the standalone /message page.
- Relayfile -> file.agentrelay.com/v1, the domain content/docs/file/cloud.mdx
names for the hosted data plane. The SDK, Python SDK and CLI pages were
sending users to api.relayfile.dev; the /file page also carried a bogus
/relayfile/v1 path prefix, where the API reference documents /v1/workspaces.
The homepage webhook snippet posted to a POST /v1/webhooks endpoint that does
not exist, with a {channel,text} body and no auth. Inbound webhook URLs are
minted per webhook by relay.webhooks.createInbound(), so the snippet now shows
the opaque URL as an environment variable with the documented {message,author}
body and bearer token.
The api-catalog test now pins both anchors so a fabricated host fails the build
rather than shipping.

None of the *.dev API domains the site advertised exist. Sweeping them, leaving the archived 7.1.1 docs alone since those record what that release actually shipped with. Where a real host is documented, references now point at it: - /message (Relaycast) -> cast.agentrelay.com/v1, per the base-URL table in content/docs/relaycast-api.mdx. - The homepage A2A agent card showed relay.dev/a2a/scout; the A2A gateway is served at the engine root without /v1, so it is cast.agentrelay.com/a2a/scout. - content/docs/observer.mdx -> observer.agentrelay.com, matching the cast/file/history subdomain pattern. The surrounding section is about pointing the CLI at a non-production deployment. Where no host exists, the curl examples take a base-URL environment variable instead of naming one, the way content/docs/file/api-reference.mdx already does with RELAYFILE_BASE_URL: - /auth -> $RELAYAUTH_BASE_URL - /schedule -> $RELAY_CRON_BASE_URL, matching the RELAY_CRON_API_KEY already in that snippet. Two clickable CTAs pointed at app.agentcron.dev. Both now link the RelayCron repo, which content/blog/just-give-the-agent-files.mdx already references and which matches the relayauth/relayfile/relaycast repo links on the same primitives page. The /schedule CTA gained target/rel, which the equivalent link on the primitives page already had.

Why
Prompted by agentrelay.com scoring 69/100 on is-agentic.com's AI-agent readiness scan. It grew a second half: building the API catalog surfaced that the API hosts the site advertises don't exist.
Caveat on scope: the scan host and
agentrelay.comitself are both blocked by this environment's egress proxy, so I could not read the failed-check list, re-scan to verify a score, or reach any of the hosts discussed below to confirm what resolves. Everything here comes from the codebase and an offline audit against the criteria the scanner publishes. Treat the score impact as unverified.Part 1 — discovery surfaces
The site was already strong on retrieval: server-rendered content,
llms.txt, per-page.mdmirrors, canonicals, sitemap, RSS. The gaps were in discovery and cross-origin access — an agent arriving cold had no way to find the security contact, the HTTP APIs, or the MCP server, and nothing it fetched was readable from another origin./.well-known/security.txt(RFC 9116)/.well-known/api-catalog(RFC 9727)/.well-known/mcp.jsonagent-relay mcplaunch — command, args, required env — rather than a remote URL, since the server ships in the CLI.llms.txt, the markdown mirrors,feed.xml,sitemap.xml,robots.txtand the well-known documents were same-origin only, so unreadable to any browser-based agent. PlusX-Content-Type-Options: nosniffsite-wide.Organization/WebSite/SoftwareApplication, cross-referenced by@idso any single page resolves its publisher.<link rel="alternate">on every pagerobots.txtcrawler coverage*rule; several of these bots treat "no rule for me" more conservatively than an explicitAllow.Two implementation notes:
app/well-known/with anext.config.mjsrewrite onto the canonical/.well-known/*paths. The internal path carriesX-Robots-Tag: noindexand arobots.txtdisallow so only the canonical URL is advertised.OPTIONShandlers for CORS preflight, deliberately. Exporting a second method opts a route handler out of static prerendering — I tried it, and it turned/llms.txt,/skill.mdand the markdown mirrors from ISR into dynamic, which the existing code comments call out as broken on the Workers runtime.Access-Control-Allow-Methodsis thereforeGET, HEAD, which is accurate; the simple GETs agents make are never preflighted.Part 2 — fabricated API hosts
Writing the catalog meant naming the APIs, which is where this surfaced:
api.agentrelay.comdoes not exist, and neither do the*.devAPI domains. Corrected sitewide, with the archivedcontent/docs/7.1.1/left alone since it records what that release actually shipped with.Where a real host is documented, references point at it:
/messageapi.agentrelay.com,api.relaycast.devcast.agentrelay.com/v1, per the base-URL table incontent/docs/relaycast-api.mdx/file, file SDK/CLI/Python docsapi.agentrelay.com/relayfile/v1,api.relayfile.devfile.agentrelay.com/v1— the domaincontent/docs/file/cloud.mdxnames, and the path the API reference documentsrelay.dev/a2a/scoutcast.agentrelay.com/a2a/scout— the A2A gateway is served at the engine root without/v1content/docs/observer.mdxobserver.relaycast.devobserver.agentrelay.comcontent/docs/loop/sources.mdxapi.relaycast.devcast.agentrelay.com/v1Where no host exists, the curl examples take a base-URL environment variable instead of naming one, the way
content/docs/file/api-reference.mdxalready does withRELAYFILE_BASE_URL:/authuses$RELAYAUTH_BASE_URL,/scheduleuses$RELAY_CRON_BASE_URL(matching theRELAY_CRON_API_KEYalready in that snippet).Two other fixes fell out:
POST /v1/webhooksendpoint that does not exist, with a{channel,text}body and no auth. Inbound webhook URLs are minted per webhook byrelay.webhooks.createInbound(), so it now shows the opaque URL as an environment variable with the documented{message,author}body and bearer token.app.agentcron.dev. Both now link the RelayCron repo, whichcontent/blog/just-give-the-agent-files.mdxalready references and which matches the relayauth/relayfile/relaycast repo links on the same primitives page.The api-catalog test pins both anchors, so a fabricated host fails the build rather than shipping.
Still worth a look
content/docs/file/cloud.mdxdescribesfile.agentrelay.comas "a rebuild in progress". The SDK, CLI and Python pages now send users there, so if that migration hasn't landed, those docs are early.content/docs/7.1.1/still containsapi.relaycast.devin two places, left intact by choice.Testing
