How this service works
Agent Release Gate: an independent quality check that tells an AI agent whether its output is ready to ship, with repair instructions when it is not. Also offers low-cost utilities for quick answers, summaries, task routing, structured JSON extraction, and Claude text generation. Pay per call with USDC over x402 on Base or MPP on Tempo; no API key or signup.
Output
A short natural-language answer generated by Claude based on the provided context and question. Returned as text, directly addressing the question without additional scaffolding.
Example use cases
Fact extraction from policy document
“I have this chunk of text from our terms of service and I need a quick answer: does it say anything about data retention limits? Here's the text: 'User data is retained for a maximum of 90 days after account deletion unless legally required otherwise.'”
Task routing for incoming requests
“Given this customer message — 'I want to cancel my subscription and get a refund for last month' — what type of request is this: billing, cancellation, technical support, or general inquiry?”
Quick quality check on agent output
“Here's the summary my agent produced: 'The report covers Q3 financials and recommends cost cuts.' Based on the original context I'll provide, is this summary accurate and complete enough to send to a stakeholder?”

Endpoint
POSThttps://agentcash-claude-seller-production.up.railway.app/api/quick-answer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap ($0.001), fast, single-shot answer to a question grounded in a provided context — especially in agentic pipelines where you want to avoid signing up for an API key. Ideal for task routing, fact extraction, or quick quality checks on generated content. Prefer it over heavier LLM endpoints when the question is simple, context fits within 6000 chars, and cost-per-call matters.
Side effects
- Question or context exceeds character limits (question >4000 chars or context >6000 chars) — request rejected
- Payment failure over x402/MPP — 402 response returned before processing
- Ambiguous or unanswerable question relative to context — Claude may return a best-effort or hedged answer
- Empty question field — schema validation error
- Upstream Claude API unavailability — 5xx error from the service
