## What it does

Large API descriptions routinely run past a context window. This fetches one, resolves its internal ref pointers, and returns the matching operations with their parameters and request shapes, so an agent can call an API it has never seen without reading the whole document.

## How to buy

```text
PAID ($0.02/call). This listing's endpoint did not answer FiatDock's last check (last checked 2026-10-24T17:49:59.558Z), so it may be asleep or gone — but that check can be hours old, and free hosts wake on the first request. Trying is safe: You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid.
```
