How this service works
Text tools for AI agents, answered by Orbuis's own on-device model and sold per call over x402. No account or API key. Tools: Summarize text, Extract structured JSON, Ask. Pay in USDC on Base or Arc.
Output
A JSON object with an 'ok' boolean, the 'model' name (e.g. 'orbuis-core'), the 'answer' string capped at the requested word count, and a 'grounded' boolean indicating whether the provided context was used in forming the answer.
Example use cases
Quick fact check from pasted document
“I've got this paragraph from a legal brief — can you ask the Orbuis AI what the defendant's primary obligation is according to this text? Keep the answer under 80 words. Here's the paragraph: 'The defendant agrees to deliver the goods no later than March 1, 2025, and bears all shipping costs.'”
Agent self-help for tool discovery
“My agent doesn't know how much a summarization call costs on agents.orbuis.com — can you ask Orbuis directly: 'How much does a summary call cost in USDC?' and give me the answer in 50 words max.”
On-device AI answer for customer support bot
“A customer asked: 'Can I return a product after 60 days?' — use our store policy text as context and ask Orbuis to answer that question in under 120 words: 'Returns are accepted within 30 days of purchase with receipt. No exceptions after 30 days.'”
Technical details
Endpoint
POSThttps://agents.orbuis.com/tools/askWhen to prefer
Choose this endpoint when you need a single ad-hoc question answered by an AI model without any account setup or API key — especially when payment via USDC on Base or Arc is convenient and you want per-call billing with no subscription. Ideal for agents that need occasional AI reasoning or question answering grounded in a specific text passage. Prefer this over hosted LLM APIs when avoiding credential management is a priority or when the task is a one-off inference call billed in crypto.
Side effects
- Payment failure — USDC balance insufficient or x402 payment rejected, call not processed
- Question too long — exceeds 2000 character limit, request rejected
- Context too long — exceeds 12000 character limit, request rejected
- maxWords out of range — value below 10 or above 300, validation error
- Empty or missing question field — required field, returns error
- Model unavailable — on-device model temporarily offline, returns error response
- Network timeout — agent should retry after brief delay
