How this service works
D&D 5e Rules Lookup: spells, monsters, classes, items (SRD). Dungeons & Dragons 5e rules lookup (SRD 5.1): spells, monsters with full stat blocks, classes, races, equipment, magic items, conditions and rules text.
Output
Returns a JSON object indicating whether the requested resource was found (found: boolean), the name of the resource, its category (spell, monster, class, item, condition, etc.), and full details such as stat blocks, descriptions, damage dice, ranges, components, spell levels, saving throws, and other relevant rules text from the D&D 5e SRD 5.1.
Example use cases
Spell rules lookup mid-session
“Quick, what does the Sleep spell do in D&D 5e? I need the range, area of effect, and how many hit points it affects.”
Monster stat block for encounter prep
“Pull up the full stat block for a Mind Flayer from the D&D 5e SRD — I need its AC, hit points, abilities, and actions.”
Class feature reference for character building
“What are the features and abilities of the Ranger class in D&D 5e according to the SRD? I'm building a character and want to see all the class details.”

Endpoint
GEThttps://saylorinnovations.com/api/dnd/spells/fireball?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, structured access to D&D 5th Edition SRD rules content — spells, monsters, classes, items, or conditions — without maintaining your own rules database. Ideal for tabletop RPG assistants, character builders, encounter planners, or game masters needing rules references mid-session. Best when you need the open SRD 5.1 content specifically; if you need content from non-SRD sourcebooks, this endpoint will not have it.
Side effects
- Resource not found in SRD (found: false) — non-SRD content like many monsters from official supplements are not included
- Misspelled or ambiguous resource names may return no results
- Content not in the SRD 5.1 open license (e.g. proprietary WotC-only content) will not be available
- Rate limiting or payment failures at $0.001 USDC per call via x402 protocol
