How this service works
Answer a short question, optionally using provided context, for lightweight context QA and agent reasoning steps. Pay up to $0.003 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.
Output
Returns a JSON object with a 'text' field containing a concise AI-generated answer to the submitted question, optionally informed by the provided context.
Example use cases
Customer support ticket auto-responder
“I need you to answer this support question quickly: 'How do I reset my password?' Here's the customer's account context: 'User has a legacy email address on file.' Give me a concise answer I can send back immediately.”
Research paper question extraction
“Can you answer this research question using the abstract I'm providing: 'What methodology was used in this study?' Here's the full abstract text to pull from, and keep your answer to under 300 tokens so I can cite it directly.”
Real-time chatbot fact lookup
“My chatbot just got asked: 'What's the difference between renewable and non-renewable energy?' Can you give me a quick, accurate answer with that background context included, so I can serve it to the user in under a second without hitting my subscription limits?”
Technical details
Endpoint
POSThttps://gpt55.558686.xyz/v1/tools/answerWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call AI question-answering capability without a subscription, especially when you want to leverage GPT-5.5 with optional context injection and control over token budget and temperature. Prefer this over full chat completion endpoints when you just need a single concise answer rather than a multi-turn conversation.
