Companion Backstory Generator

Choose this endpoint when you need structured companion character backstories with explicit personal goals and story complications — especially when you want thematic coherence with a specific game world or lore context, or when reproducibility via seed is needed for playtesting. Prefer this over general NPC generators when the character must be a companion role with narrative depth rather than a one-off NPC profile.

• count exceeds maximum of 5 — returns validation error
• malformed input schema — returns 400 bad request
• payment failure via x402 protocol — returns 402 payment required
• theme or context strings too long or unsupported — may return truncated or generic output
• seed provided but not recognized format — may still generate but reproducibility not guaranteed
