## When to prefer this

Choose this endpoint when you want to interact with a Nitrograph-branded AI agent via the Questflow swarm platform, particularly for questions related to crypto, blockchain, Web3, or market topics. Prefer this over generic LLM APIs when you specifically need the Nitrograph persona or Questflow swarm orchestration, or when you are building workflows that integrate with the x402 payment protocol.

## Known failure modes

- Missing required 'input' field returns a validation error
- Empty or overly vague messages may produce low-quality or generic responses
- Payment failure via x402 protocol results in a 402 Payment Required response
- Agent may not have up-to-date information on very recent events
- Swarm agent may occasionally produce hallucinated or inaccurate content
