Example prompt: Summarize this blog post into bullet points using 24K Labs: 'Artificial intelligence is transforming healthcare by enabling faster diagnosis, personalized treatment plans, and predictive analytics that help clinicians anticipate patient deterioration before it occurs. However, concerns around data privacy, algorithmic bias, and regulatory approval remain significant barriers to widespread adoption.'

## When to prefer this

Choose this endpoint when you need quick, pay-per-use AI summarization without managing API keys or subscriptions. Ideal for agents that summarize content infrequently or on-demand and want to pay only for what they use via USDC on Base L2. Best for bullet-point style summaries powered by Claude Haiku.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Missing required 'code' (content) field — may return empty or error response
- Content too long for model context window — truncation or error
- Network timeout on Base L2 payment processing — request fails
- Invalid USDC transaction on Base L2 — payment rejected, no summary returned
