## 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 collectablespulse-grading-service-guide-d814782c
```

Example prompt: I have a 1986 Fleer Michael Jordan rookie basketball card in what looks like near-mint condition — should I get it graded, and if so, which service should I use, how much will it cost, and how long will it take?

## When to prefer this

Use this endpoint when a collector or investor agent needs to decide whether to submit an item for third-party grading and which of the major grading companies (PSA, BGS, CGC, PCGS, NGC) is most appropriate. Prefer this over generic web search when you need structured, actionable grading guidance with cost and turnaround data in a single call.

## Known failure modes

- Unrecognized or insufficiently described item type returns generic or null recommendations
- Very obscure collectibles may not have grading service coverage
- Grading costs and turnaround times may be outdated if services change pricing
- Missing item condition input may result in incomplete worth-grading assessment
