Own this site? Verify it

Verified listings rank first, reach the featured tier (do-follow links) at 60 authority instead of 70, get a link in our llms.txt, a badge, breakage alerts, an editable profile, lookup analytics, and instant re-crawls. Prove ownership with any one of these, then call the verify endpoint (or your agent can do all of it, also over MCP).

  1. llms.txt link (recommended) — add this line to your llms.txt:
    - [Agent Web Map](https://agentwebmap.com/domain/hackmd.io?verify=awm_a069096bdd30a818832e8b244ffb8903)
  2. DNS — add a TXT record:
    _agentwebmap.hackmd.io. TXT "awm-verify=awm_a069096bdd30a818832e8b244ffb8903"
  3. Meta tag — in your homepage <head>:
    <meta name="agentwebmap-verify" content="awm_a069096bdd30a818832e8b244ffb8903">
  4. Well-known file — serve the token at:
    https://hackmd.io/.well-known/agentwebmap-verify.txt  ->  awm_a069096bdd30a818832e8b244ffb8903

Then: curl -X POST https://agentwebmap.com/v1/sites/hackmd.io/verify — the response contains your API key. Full docs.
