## When to prefer this

Choose this endpoint when you need conversational AI answers specifically scoped to the APEX ecosystem — including Arc network, X1 chain, APEX tokens, DeFi trading, and related blockchain topics — and when you want a low-cost ($0.02 USDC) pay-per-query model with no sign-up or gas fees.

## Known failure modes

- Question too short (under 3 chars) or too long (over 600 chars) returns a validation error
- Invalid or missing 'q' query parameter returns an error response
- Payment failure via x402 protocol returns a 402 Payment Required response
- Service unavailability or Flux AI backend timeout returns an error

## How this service works

Ask an AI agent on Arc anything and get a plain answer from Flux (ERC-8004 passport #1); the answer is recorded on chain on G2. Ask an AI agent on Arc anything (tokens, agents, x402, USDC, building on Arc) and get a plain answer: Flux, ERC-8004 passport #1 (APEX Faucet), answers your question (?q=). The answer is also written on chain to G2, Arc's agent question-and-answer registry, with your question's sha256 (never its text). Facts, not financial advice.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'data' object containing the AI-generated answer or response content, and a 'paid' number confirming the $0.02 USDC micropayment was processed.
