Getting Started

Quickstart

Generate your first file with the API in three steps.

Before you begin: create an account

API keys live in your account, so you need one first:

  1. Sign up at llms-txt.io/sign-up — with Google, or an email and password.
  2. If you signed up with email, verify it before logging in. We send a verification link to your inbox — click it before you try to sign in, or the login won't go through. Check your spam folder if it hasn't arrived in a minute. (Signing up with Google skips this step.)
  3. Sign in at llms-txt.io/login.

The API and managed sites are paid features — see Pricing. The web generator stays free and needs no account.

1. Create an API key

Once you're signed in, open Account → API keys and click Create key. Copy the key immediately — it's shown only once and looks like:

text
llmstxt_sk_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Treat your key like a password. It's stored only as a hash on our side, so a lost key can't be recovered — just revoke it and create a new one.

2. Generate a file

Send a POST to the generate endpoint with your key in the x-api-key header:

bash
curl https://llms-txt.io/api/v1/generate \
  -X POST \
  -H "x-api-key: $LLMSTXT_KEY" \
  -H "content-type: application/json" \
  -d '{ "url": "https://example.com", "fileType": "both" }'

The response contains both files as strings:

json
{
  "url": "https://example.com",
  "domain": "example.com",
  "fileType": "both",
  "llmsTxt": "# Example\n\n> A one-line summary…",
  "llmsFullTxt": "# Example\n\n## Page title\n…",
  "llmEnhanced": true,
  "note": null
}

3. Validate it (optional)

Lint a file — by URL or raw content — before you publish:

bash
curl https://llms-txt.io/api/v1/validate \
  -X POST \
  -H "x-api-key: $LLMSTXT_KEY" \
  -H "content-type: application/json" \
  -d '{ "url": "https://example.com" }'
