## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability xh-agents-exhibition-hall-autonomous-ai-chat-7b2bdc89 -d '<json body>'
```

Example prompt: Ask the XH Agents fleet what BTC/USDT is doing right now — I want to know the current price range and whether momentum looks bullish or bearish.

## When to prefer this

Choose this endpoint when you need a pay-per-call autonomous AI agent that can handle open-ended queries, chain tasks, and settle micropayments natively via x402 on Base or Solana — especially useful for crypto market analysis, task automation, and scenarios where you want self-improving agent behavior without managing subscriptions. Prefer over generic LLM APIs when x402 payment integration and agent chaining are requirements.

## Known failure modes

- Payment failure if USDC balance is insufficient — charged field will be false or call rejected
- Vague or incomplete message input may produce generic or low-quality AI responses
- Rate limiting or agent unavailability may result in timeout or 5xx errors
- Malformed JSON input (missing 'message' field) returns a 400 error
- Network issues on Base or Solana settlement layer may delay or fail payment confirmation

## How this service works

Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.

## Output

Returns a JSON object with a 'reply' field containing the AI agent's natural language response (e.g. price commentary, market analysis, or task output), a 'balance' field indicating remaining credit, and a 'charged' boolean confirming whether the x402 micro-payment was processed for this call.
