## When to prefer this

Choose this endpoint when you need to invoke AI agent tools or aggregated services without managing individual API keys or subscriptions, and when you want a single pay-per-call gateway billed in USDC. Ideal for AI agents that need access to diverse capabilities (RSS parsing, business lookup, news aggregation, etc.) through one unified interface with minimal setup friction.

## Known failure modes

- Insufficient USDC balance in x402 wallet returns a 402 Payment Required error
- Unknown or invalid tool identifier returns a 404 or routing error
- Underlying service unavailable returns a timeout or 503 error
- Malformed request payload returns a 400 validation error
- Network or blockchain confirmation delays may slow payment processing

## Output
