How this service works

Pay-per-call AI inference for agents: chat (Llama 3.3 70B / 3.1 8B), structured JSON, summarize, translate (incl. Egyptian Arabic), extract, classify, sentiment, keywords, rewrite, embeddings, moderation, vision and speech-to-text. USDC on Base mainnet over x402. No API key, no account.

Output

Returns a JSON object containing the rewritten text in the requested tone, the tone label applied, and the model used (e.g. @cf/meta/llama-3.3-70b-instruct-fp8-fast).

Example use cases

Formalizing customer support responses

“Take this support message and rewrite it in a formal tone: 'Hey, sorry about the mess! We know things are broken and our team is literally on it right now, hang tight!'”

Simplifying legal or technical copy

“Rewrite this clause in simple language so a non-lawyer can understand it: 'The licensee shall indemnify and hold harmless the licensor from any and all claims arising out of the licensee's use of the licensed materials.'”

Converting product copy to marketing tone

“Rewrite this plain product description in a marketing tone to make it more persuasive: 'Our app lets you track your daily expenses and see where your money goes each month.'”

When to prefer

Choose this endpoint when you need tone-controlled text rewriting without managing API keys or subscriptions — ideal for agents that need to pay per call in USDC via the x402 protocol. It is especially useful when you need one of four well-defined tones (formal, casual, marketing, simple) and optionally want output in a specific language. Prefer over hosted LLM APIs when you need permissionless, accountless, micropayment-based access.

Side effects

Text exceeds 4000 character limit — request rejected
Invalid tone enum value — returns error
Payment not settled in USDC on Base mainnet — 402 response blocks the call
Malformed ISO 639-1 language code — may default or error
Model latency spike causing timeout on long texts
