Technical details
Endpoint
POSThttps://aimomo.vercel.app/api/searchWhen to prefer
Choose this endpoint when you need a one-off AI-generated answer without a subscription, want to pay per query in USDC on Base via x402, or are building a crypto-native agent pipeline that requires micropayment-gated LLM access. Prefer alternatives (OpenAI, Anthropic direct APIs) if you need fine-grained model selection, system prompts, multi-turn conversation, or high-volume queries where per-call pricing is expensive.
Side effects
- Payment not included or rejected — returns 402 Payment Required
- Missing required 'query' field — returns 400 Bad Request
- Query too long or malformed — model may return empty or truncated answer
- Insufficient USDC balance — payment fails before request is processed
- Service unavailable on Vercel — returns 500 or 503
