# How do I get a fund's name from its ISIN?

**Short answer:** Call GET https://fundfactsapi.com/api/v1/funds/{isin} with a bearer API key and read name (envelope) in the JSON response (related fields: data.shareClass, data.keyFacts.manager / currency). The name is read from the fund house's product page and matches the share-class name in the prospectus. The Free plan gives 5 lookups a month with no card, and the keyless demo endpoint shows the shape for an already-loaded fund.

## Where it is in the response

| Path | Type | Meaning |
|---|---|---|
| `name (envelope)` | `string or null` | Official share-class name, e.g. "iShares Core MSCI World UCITS ETF". |
| `data.shareClass` | `string or undefined` | Share-class label when it can be inferred. |
| `data.keyFacts.manager / currency` | `string` | Manager and share-class currency. |
| `GET /search?q=` | `results[]` | Name → { isin, name, issuer, currency, assetClass, shareClass, income, category }; free. |

Sample for iShares Core MSCI World UCITS ETF ([IE00B4L5Y983](https://fundfactsapi.com/funds/IE00B4L5Y983)):

```json
{
  "isin": "IE00B4L5Y983",
  "name": "iShares Core MSCI World UCITS ETF",
  "data": { "shareClass": "USD Acc", "keyFacts": { "currency": "USD", "manager": "ETF" }, "structure": "ETF" }
}
```

## Where the figure comes from

The name is read from the fund house's product page and matches the share-class name in the prospectus. The reverse direction, name to ISIN, is `GET /search?q=msci world`; it is free and returns issuer, currency, share class and distribution policy per result so you can pick the right class before spending a request.

## The request

```bash
curl -s --max-time 300 https://fundfactsapi.com/api/v1/funds/IE00B4L5Y983 \
  -H "Authorization: Bearer $FUNDFACTS_API_KEY" | jq '.name'
```

```python
import os, requests
r = requests.get("https://fundfactsapi.com/api/v1/funds/IE00B4L5Y983",
                 headers={"Authorization": f"Bearer {os.environ['FUNDFACTS_API_KEY']}"}, timeout=300)
fund = r.json()
print(fund["name"], fund['name'])
```

```javascript
const res = await fetch("https://fundfactsapi.com/api/v1/funds/IE00B4L5Y983", {
  headers: { Authorization: `Bearer ${process.env.FUNDFACTS_API_KEY}` },
  signal: AbortSignal.timeout(300_000),
});
const fund = await res.json();
console.log(fund.name, fund.name);
```

Sign up at [fundfactsapi.com/signup](https://fundfactsapi.com/signup) for a key; the Free plan is 5 lookups a month with no card. Without a key, `GET https://fundfactsapi.com/api/v1/demo/funds/IE00B4L5Y983` returns the same payload for funds already in the store (30 calls a minute per IP; it never loads a new fund).

## Caveats

- Search covers funds that have already been loaded by someone; a fund nobody has requested yet is found by ISIN, not by name.
- For a stock, bond or index ISIN the answer is 404 fund_not_found: the API only knows funds.

## Several funds at once

`POST /funds` with `{ "isins": ["…", "…"], "wait": true }` returns the same payload for up to 10 ISINs per call on Starter, 50 on Pro and 200 on Scale. One request is counted per fund found. `X-RateLimit-Remaining` on every response tells you how many are left this month; a `429 rate_limited` response carries `Retry-After`. Search and `/me` are free.

A fund never loaded before is read on demand from the documents the fund house publishes. That first call takes 15 seconds to about 3 minutes; set your client timeout to 300 seconds and do not fire a second request for the same ISIN while the first is running. Every later call returns from the store in well under a second with `cached: true`; past 24 hours the payload comes back flagged `stale: true` while a refresh runs in the background, and nothing older than 7 days is served without a new read.

Everything else in the payload is listed in the [field reference](https://fundfactsapi.com/docs/fields).

## FAQ

### Can I look up a fund by ticker, WKN or SEDOL?

Not directly: the key is the ISIN. Search by name usually finds the fund in one step, and the ISIN is printed on every factsheet and broker page. The glossary explains how ISIN, ticker, SEDOL, WKN and CUSIP relate.

### Do I need a credit card to try it?

No. The Free plan is 5 lookups per month with no card; sign up with an e-mail address or Google and the key is shown in the dashboard.

### Which ISINs work?

Any share class of a UCITS fund, ETF, money-market fund or open-end fund whose management company publishes a product page, factsheet and KID. Each share class has its own ISIN and is looked up on its own. Stocks, bonds and indices are not funds and return 404 fund_not_found.

### How current are the figures?

Each ISIN is re-read from the fund house's documents at most every 24 hours; a request past that is answered at once from the store (stale: true) while the refresh runs in the background. data.dataAsOf is the as-of date printed on the documents, typically the last month end for a factsheet and the last trading day for holdings files.

## About FundFacts API

FundFacts turns any fund or ETF ISIN into one dated factsheet (fees and KID costs, the 1–7 risk indicator, holdings, sector and country exposure, returns) read from the fund house's own documents: as a client-ready PDF under your firm's name for advisers and wealth managers, as JSON through its API for developers, or inside ChatGPT and Claude through its MCP server.

FundFacts works inside ChatGPT and Claude as a connector (a remote MCP server): ask about any fund or ETF by ISIN, ticker or name and the assistant answers from FundFacts' dated figures, fees, risk, holdings, exposure and returns, with fund cards, side-by-side comparisons, holdings overlap and portfolio look-through.
