Endpoints

• GET /api/robots.json — every robot's current record.
• GET /api/robots/<slug>.json — one robot, e.g. /api/robots/unitree-g1.json.

Fields on each robot record

• slug — Kebab-case identifier, e.g. "tesla-optimus" — used in URLs and filenames.
• name — Model name.
• maker — Manufacturer or organization.
• category — "humanoid", "quadruped", or "biped".
• locomotion — "legged", "wheel-legged", or "hybrid".
• status — "concept", "prototype", "pilot", "commercial", "discontinued", or "retired".
• release_date — ISO date, or null if unknown.
• price — amount (number or null) and currency (ISO 4217) and date the price was last confirmed — currency and date are null whenever amount is null, never a currency with no amount.
• specs — Category-specific fields (height_cm, weight_kg, etc.) — varies by category.
• product_url — The manufacturer's official product page.
• links — video, docs, and price_source URLs — each null when not published for this robot.
• canonical_url — This robot's page on robocensus.com.
• image — status ("photo" or "glyph"), url, and credit (present only for Creative Commons images). image.url is outside the CC BY data license — see above.

Good to know

• These are static snapshots regenerated on every deploy, not a live query API — sources themselves are re-checked on a rolling 3-day cycle.
• The schema may still evolve before a 1.0 — that's what schema_version is for.
