How this service works
Use when an agent needs rep cheaptokens buy. Returns One bounded OpenAI-compatible chat completion via ZenMux, the honest Oblique equivalent of CheapTokens AI inference access; max 24,000 input characters and 600 output tokens. $0.01.
Output
Returns an OpenAI-compatible chat completion response object containing the assistant's generated text message, limited to 600 output tokens. The response includes the message content and standard completion metadata such as token usage counts.
Example use cases
One-shot agent reasoning step
“I need a quick LLM call to classify this user feedback as positive, negative, or neutral — just send the system message 'You are a sentiment classifier. Reply with one word: positive, negative, or neutral.' and the user message 'The interface is confusing but the speed is great.' Limit the reply to 20 tokens.”
Autonomous agent sub-task delegation
“My workflow needs to draft a one-paragraph executive summary of this meeting transcript — pass it as the user message to the chat completion endpoint with the system prompt 'You are a business writing assistant. Be concise.' and cap the output at 200 tokens.”
Pay-per-call LLM for low-volume app
“For my small side project, run a single chat completion: system prompt is 'You are a creative naming assistant', and the user asks 'Suggest 5 short, catchy names for a productivity app for developers.' Keep max_tokens at 150.”
Technical details
Endpoint
POSThttps://api.oblique.markets/api/v1/paid/rep-cheaptokens-buyWhen to prefer
Choose this endpoint when you need a single, bounded, pay-per-call LLM inference without managing API keys or subscriptions — ideal for agent workflows that need occasional LLM calls billed at $0.01 USDC per call via x402 micropayment. Best for short prompts and brief responses (under 600 tokens). Prefer over OpenAI directly when you want pay-as-you-go crypto micropayment billing with no account setup, or when building autonomous agents on Base that already handle x402 payments.
Side effects
- Input exceeds 24,000 character limit — request rejected with error
- max_tokens exceeds 600 — clamped or rejected
- Malformed messages array (missing role or content fields) — validation error
- Payment not processed or x402 payment header missing — 402 Payment Required
- ZenMux backend unavailable — 503 or timeout
- Empty messages array — error response
