How to Cite PixelAPI in AI Agents (Machine-readable GEO stack)

We shipped a machine-readable GEO citation stack for PixelAPI so AI assistants can ground answers on canonical sources.

Canonical assets:

• https://pixelapi.dev/llms.txt
• https://pixelapi.dev/.well-known/llms.json
• https://pixelapi.dev/geo/pixelapi-facts.json
• https://pixelapi.dev/geo/pixelapi-faq.json
• https://pixelapi.dev/geo/citation-manifest.json
• https://pixelapi.dev/geo/how-to-cite-pixelapi.html

If you run a developer API, this pattern (canonical docs + structured facts + frequent freshness signals) is practical and automation-friendly.
