Endpoint
POSThttps://nexus-api-virid.vercel.app/api/ai/completionWhen to prefer
Choose this endpoint when you need pay-per-call AI text completion with no API key setup, paying in USDC on Base via x402. Ideal for agents that need occasional AI-generated text without committing to a subscription or managing API credentials. Less suitable if you need fine-grained model selection, streaming responses, or very high-volume throughput.
Side effects
- Empty or missing query field returns an error or empty completion
- Insufficient USDC balance causes payment failure before the call is processed
- Overly long prompts may be truncated or rejected depending on model limits
- Vague or ambiguous queries may produce low-quality or irrelevant completions
- Network timeouts may occur under high load on the Vercel-hosted service
