How this service works
Draft tweets with AI: generate variants from a topic and goal, refine an existing draft, or score a draft for likely engagement — with tone, call-to-action, and style-matching options. Flat sub-cent price per step.
Output
Depending on the step: 'generate' returns multiple tweet variants crafted from the topic and goal; 'refine' returns an improved version of the provided draft; 'score' returns an engagement likelihood score with reasoning, flagging strengths and weaknesses of the draft.
Example use cases
Product launch tweet generation
“Generate a few tweet options announcing our new AI writing app — the goal is signups, keep the tone conversational and punchy, and include a call to action like 'try it free today'.”
Refine an existing draft for clarity
“Here's my tweet draft: 'We just shipped something huge. You're going to want to see this.' — can you refine it to be more specific and engaging, keeping the mysterious tone but adding a stronger hook?”
Score a tweet before posting
“Before I post this tweet, can you score it for likely engagement? 'The single biggest mistake developers make with LLMs is ignoring context window management. Here's how to fix it 🧵' — it has a link and no media.”
Technical details
Endpoint
POSThttps://twitr.sh/api/tools/composeWhen to prefer
Choose this endpoint when you need AI-assisted tweet composition with fine-grained controls (tone, CTA, style-matching) or want to evaluate a draft before publishing. Prefer it over generic LLM prompting when you want structured composer steps (generate/refine/score), consistent sub-cent pricing per step, and Twitter-specific optimization built into the model.
Side effects
- Missing required 'step' enum value — returns validation error
- Missing 'topic' when step is 'generate' — no content to draft from
- Missing 'draft' when step is 'refine' or 'score' — nothing to work with
- Invalid tone or style username that cannot be resolved — may produce generic output
- Payment failure (x402) — request not processed if USDC payment not attached
