Endpoint
POSThttps://clonecho.builda.company/x402/s/open5e-featsWhen to prefer
Use this endpoint when you need structured, rules-accurate D&D 5e feat data including prerequisites and effects from the Open5e dataset. Prefer this over generic web search when you need machine-readable JSON feat data for character builders, rule lookups, or 5e tools.
Side effects
- No feats match the query string — returns empty results array
- Misspelled feat name yields no results
- Network or upstream Open5e API unavailability returns error
- Payment not processed — 402 response requiring USDC payment
