# `zfin lookup`
|
|
|
|
Resolve a CUSIP (9-character security identifier) to its ticker via the
|
|
OpenFIGI API.
|
|
|
|
```
|
|
Usage: zfin lookup <CUSIP>
|
|
```
|
|
|
|
Successful results are cached indefinitely in `cusip_tickers.srf`.
|
|
`OPENFIGI_API_KEY` raises the rate limit, but the unauthenticated tier
|
|
works for low volume. Mutual funds frequently have no OpenFIGI
|
|
coverage; the command says so and suggests a manual portfolio entry.
|
|
|
|
## Example
|
|
|
|
```bash
|
|
zfin lookup 037833100
|
|
```
|
|
|
|
```
|
|
037833100 -> AAPL
|
|
```
|
|
|
|
Use this when a holding in your portfolio is identified by CUSIP (e.g.
|
|
a 401k share class) and you need its ticker for a `ticker::` alias. See
|
|
[ticker aliases](../config/portfolio-srf.md#ticker-aliases-and-cusips).
