## When to prefer this

Choose this endpoint when you need keyless, pay-per-use text summarization using the BART model, especially when you want to pay with USDC on Base, Polygon, Arbitrum, World, or Solana via x402 without setting up API credentials. Ideal for agents that handle one-off summarization tasks and prefer crypto micropayments over subscription-based API keys.

## Known failure modes

- Input text missing or empty — endpoint returns an error
- max_length value is invalid (e.g. negative or non-integer) — may return a 400 error
- Payment in USDC not fulfilled — returns HTTP 402 Payment Required before processing
- Text too long for model context window — may return a 500 or truncation error
- Network timeout on the Cloudflare Workers edge — returns a timeout error
