## 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 scribed-glossary-cohort-definition-1f8a4a9b
```

Example prompt: Look up the definition of 'cohort' from the Scribed glossary on PennyPress — it costs a penny per lookup and returns the machine-readable gloss.

## When to prefer this

Choose this endpoint when you specifically need the Scribed/PennyPress editorial definition of 'cohort' — especially when building agents that consume machine-readable glossary content from essay-based publications, or when integrating x402 micropayment-gated content retrieval. Not suitable for general dictionary lookups or bulk terminology fetching.

## Known failure modes

- Payment not received or insufficient — endpoint returns 402 Payment Required and withholds the gloss
- Term not found — endpoint may return an empty or error response if 'cohort' is not in the glossary
- Network timeout — slow response if PennyPress server is under load
- Malformed payment header — micropayment protocol not correctly implemented results in payment rejection
