## 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 rotary-agency-open5e-proxy-api-a823f576
```

Example prompt: Can you look up the stat block for the Beholder in D&D 5e using open5e data — I need its AC, HP, and special abilities?

## When to prefer this

Choose this endpoint when you need programmatic access to Open5e D&D 5th edition reference data and are already operating in an x402 micropayment context. It is a thin, zero-markup proxy of the open5e.com API billed at $0.002/call, making it suitable for agents that need occasional lookups without managing open5e API keys directly. Prefer the native Open5e API (free) if you are making high-volume requests or want to avoid per-call fees.

## Known failure modes

- Invalid or unsupported endpoint path returns an error or empty response
- Payment failure via x402 protocol results in 402 response before data is returned
- Rate limiting or upstream open5e unavailability may cause timeouts
- Misspelled resource names may return empty results rather than a helpful error
- No authentication mechanism beyond x402 micropayment
