How this service works
Free-source data APIs (100% margin, no proxy, $0.002/call): ...
Output
Returns endpoint-specific structured JSON from the Open5e dataset, such as monster stat blocks (AC, HP, speed, abilities, actions), spell descriptions (level, range, duration, components, text), class features, backgrounds, races, magic items, or other D&D 5e open-content data depending on the path and query parameters supplied.
Example use cases
Monster stat block lookup
“I'm running a D&D campaign tonight — can you pull up the full stat block for a Vampire from open5e, including its abilities, resistances, and legendary actions?”
Spell reference for character build
“What are the exact details of the Fireball spell in D&D 5th edition — damage, range, components, and spell level — from the open5e database?”
Character class feature reference
“Can you fetch the class features and progression table for the Paladin from the open5e open-source D&D data so I can plan my character build?”
Technical details
Endpoint
GEThttps://rotaryagency.uk/api/free/open5e?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Open5e D&D 5th edition reference data and are already operating in an x402 micropayment context. It is a thin, zero-markup proxy of the open5e.com API billed at $0.002/call, making it suitable for agents that need occasional lookups without managing open5e API keys directly. Prefer the native Open5e API (free) if you are making high-volume requests or want to avoid per-call fees.
Side effects
- Invalid or unsupported endpoint path returns an error or empty response
- Payment failure via x402 protocol results in 402 response before data is returned
- Rate limiting or upstream open5e unavailability may cause timeouts
- Misspelled resource names may return empty results rather than a helpful error
- No authentication mechanism beyond x402 micropayment
