Choose this endpoint when you need frictionless, one-shot text summarization with no API key or account setup — ideal for AI agents that want to pay per use with USDC on Base via the x402 protocol. Best when you need Llama-quality summaries without committing to a subscription or managing credentials.
Side effects
- Missing or malformed 'input' body returns a validation error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Body type mismatch (e.g. sending form-data when json is expected) may cause parsing failure
- Very short or empty text input may produce a trivial or empty summary
- Network timeouts on large text inputs if the model takes too long
