All splash pad data, one place

Every JSON download SplashPadHub publishes — directory, Q&A, seasonal status, comparisons, coverage, sitemap, freshness — with cURL examples, schemas, and the embedded license. Built to be agent-callable and copy-pasteable. No auth, no rate limit, 24h edge cache.

What we publish

Twenty-four free JSON endpoints, statically generated at build time and served from the edge. Each download is the canonical source for one slice of the directory — every chart, report, and embed on the site traces back to one of these files. Sizes below are approximate (compressed payloads vary slightly between deploys); each endpoint links directly to the live JSON. No API key, no signup, no rate limit. Treat the catalog as stable: endpoint URLs and field names rarely change, and any breaking change shows up in /changelog first. If you only have one round-trip to spend, fetch /api/llms-full.json — it bundles the whole site for AI grounding.

Each JSON payload also embeds the license string inline (in meta.license where present) so downstream tooling can detect terms automatically. For derivatives, name the source as SplashPadHub Research and indicate any modifications.

Schema

Every endpoint returns either a JSON array of records or a JSON object with a meta envelope plus payload. Field names are stable; missing fields stay missing rather than being filled with placeholder values, so downstream code should treat most fields as optional. Coordinates are WGS84 decimal degrees; dates are ISO 8601; timestamps are UTC. Slugs are kebab-case and unique within their entity. The two highest- traffic endpoints are pads.json (the directory itself) and qa.json (the editorial Q&A bank); their shapes anchor the rest of the catalog. Everything else either references these slugs or aggregates over them.

Sample queries

Four cURL one-liners that exercise the catalog end-to-end. Each is safe to run from a shell, an agent, or a CI job — endpoints accept anonymous GETs and respond with permissive caching headers (s-maxage=86400, 1-week stale-while-revalidate). Pipe through jq for filtering; pipe to a file for offline analysis.

Count free Texas pads

curl -s https://splashpadhub.com/api/pads.json \
  | jq '[.[] | select(.state == "Texas" and .cost == "free")] | length'

List safety-tagged Q&A questions

curl -s https://splashpadhub.com/api/qa.json \
  | jq '.[] | select(.tags | contains(["safety"])) | .q' \
  | head -10

Pull the whole-site bundle and inspect summary

curl -s https://splashpadhub.com/api/llms-full.json \
  -o llms-full.json && jq '.summary' llms-full.json

Check freshness before refetching

curl -s https://splashpadhub.com/api/freshness.json \
  | jq '{ generatedAt, version, datasets: (.datasets | length) }'

Bulk download

If you want everything in one shot — every Q&A, glossary entry, seasonal status row, state / regional / special guide, top pads, recent blog, and the endpoint catalog — pull /api/llms-full.json. It is the canonical aggregate and is what most agents fetch first.

For human-readable inclusion in prompts and citations, the same bundle is mirrored as plain text at /llms-full.txt. A summary version for quick context lives at /llms-summary.txt.

Need a slice we don't publish — region, feature, time window? Email partners@splashpadhub.com with what you need. Custom slices ship as static JSON drops, same license.

Update cadence

Endpoints rebuild on every deploy and are validated against bun run validate (geo + schema audit) before publishing. To know whether a cached copy is stale, hit /api/freshness.json first — it returns per-dataset generatedAt timestamps, the build version, and the rebuild cadence. In normal operation expect a daily snapshot.

Material directory changes (pad additions, closures, methodology updates) are recorded in /changelog and mirrored in /api/changelog.json. Seasonal status refreshes fire before Memorial Day and Labor Day; full coverage sweeps land quarterly.

Edge cache: s-maxage=86400 (24h), stale-while-revalidate=604800 (1 week) on most endpoints. Browser cache: max-age=3600. There is no rate limit and no auth, so please cache locally if you plan to hit endpoints from a bot at high volume.
