Bonus: markdown for machines

Every public listing page supports content negotiation. Ask for markdown and you get a clean, LLM-friendly version of the page from the same canonical URL — no separate endpoint.

curl -H "Accept: text/markdown" "https://launchlog.ai/listing/seoauto-io"

Good to know

The public API exposes only published listings. Private fields (owner, billing, internal status) are never returned.
Be reasonable with request volume. Heavy or abusive traffic may be rate-limited.
