D&D 2024 SRD API

A standalone, public JSON API serving three D&D 5e datasets — the official 2024 SRD 5.2 corpus, a legacy archive of original 5e + third-party material, and 2024 Expanded, which unions SRD 5.2 with community-submitted homebrew content. CORS-open, no auth required for reads. Stat blocks, level progressions, and lookup tables are parsed into structured JSON so they're queryable.

Filtering

List endpoints accept query-string filters on publisher, book, source.
?source=*SRD*Contains match (case-insensitive). * is the wildcard.
?publisher=Wizards*Starts-with.
?source=a,bOR within a single field.
?source=*SRD*&publisher=Wizards*AND across fields.
?fields=name,slug,sourceChoose which columns the list endpoint returns.

Response shape

Two envelopes — list (name+slug) and detail (full record). 
GET /api/2024/monsters
{
  "data": [ { "name": "Aboleth", "slug": "aboleth" }, ... ],
  "count": 345
}

GET /api/2024/monsters/aboleth
{
  "data": {
    "slug": "aboleth", "name": "Aboleth",
    "description":    "Aboleth Large Aberration, Lawful Evil AC 17 HP 150 ...",
    "description_md": "## Aboleth\n\n*Large Aberration, Lawful Evil*\n\n- **AC** 17\n- **HP** 150 ...",
    "properties": { "size": "Large", "creatureType": "Aberration", "stats": { ... }, "actions": { ... } },

Endpoints Legacy

Original 5e + third-party corpus. GET /api/legacy lists the resources in this namespace.
Resource List Detail
Monsters 11,463 records GET /api/legacy/monsters GET /api/legacy/monsters/{slug}
Spells 5,849 records GET /api/legacy/spells GET /api/legacy/spells/{slug}
Backgrounds 405 records GET /api/legacy/backgrounds GET /api/legacy/backgrounds/{slug}

Species 383 records GET /api/legacy/species GET /api/legacy/species/{slug}
Classes 134 records GET /api/legacy/classes GET /api/legacy/classes/{slug}

Filtering

Same filter syntax as SRD 5.2 — publisher, book, and source. Legacy data has richer publisher/book values since it includes third-party material.
?publisher=*Kobold Press*Filter by third-party publisher (contains match).
?source=*SRD*Find legacy entries that carry an SRD Source tag.
?publisher=Kobold Press,Goodman GamesOR within a single field.
?source=*5e*&book=*Tome*AND across fields.
?fields=name,slug,publisher,book,sourceChoose which columns the list endpoint returns.

Response shape

Identical envelope to SRD 5.2. Legacy records typically carry populated publisher and book fields. 
GET /api/legacy/monsters
{
  "data": [ { "name": "Aboleth", "slug": "aboleth" }, ... ],
  "count": 11,463
}

GET /api/legacy/monsters/aboleth
{
  "data": {
    "slug": "aboleth", "name": "Aboleth",
    "description": "...",
    "properties": { "Category": "Monsters", "Size": "Large", "Type": "aberration", "Source": "5th Edition SRD", ... },
    "publisher": "Wizards of the Coast",
    "book": "Systems Reference Document 5.1",
    "source": "5th Edition SRD"
  }
}

// Note: legacy responses omit `description_md` — that field is only present
// on the curated 2024 SRD tables (and inherited by the expanded namespace).

Rate limits & caching

Per client IP. Burst-friendly — short spikes pass; sustained scraping doesn't.
60 req / minutePlenty of headroom for any real UI or paginated crawl.
1,000 req / hourCatches loop-style scraping that slips under the per-minute cap.
10,000 req / daySlow-drip ceiling. Need more? Open an issue and tell us what you're building.
X-RateLimit-Limit / Remaining / ResetReturned on every response so honest clients can self-pace.
429 Too Many RequestsSent with Retry-After (seconds) when a window is exhausted.
Cache-Control: max-age=3600 & ETagSend If-None-Match to get a 304 with no body — doesn't count toward limits in practice since most clients/CDNs serve from cache.

Want to help out?

This API is 100% free — no rate-tier paywall, no ads, no tracking. Server bills and the hours behind keeping it audited / current come out of my pocket and my evenings.
