`GET https://api.wiseview.ai/v1/companies/{symbol}/value-chain`

A company's suppliers, customers, partners and competitors from WiseView's value-chain map, with the evidence for each link.

Each call counts against your allowance.

## Parameters

| Name | In | Type | What it does |
| --- | --- | --- | --- |
| `symbol` (required) | path | ticker | Stock ticker, like AAPL. |
| `types` | query | list, comma-separated, up to 8 | Only these link types, like supplier and customer. |
| `limit` | query | whole number, 1–200 | How many links. Leave it out for `60`. |

## Answer

`data`, abridged — real answers carry more fields:

```json

  "symbol": "NVDA",
  "asOf": "2026-10-21T13:00:00.000Z",
  "edges": [
    {
      "id": "6710c0ffee0000000000ab01",
      "type": "supplier",
      "direction": "direct",
      "counterparty": {

        "name": "Taiwan Semiconductor Manufacturing"
      },
      "confidence": 0.92,
      "status": "active",
      "firstSeen": "2024-02-21",
      "lastConfirmed": "2026-02-26",
      "evidence": [

          "snippet": "…wafers manufactured by Taiwan Semiconductor Manufacturing…",
          "sourceLabel": "Annual report (10-K)"
        }
      ]
    }
  ],
  "anonymousConcentration": [],
  "coverage": {
    "hasExtraction": true,
    "lastExtractedAt": "2026-10-20T00:41:00.000Z"
  }
}
```

The answer quotes text written outside WiseView and carries a `notice` saying so.

## Samples

```bash
curl "https://api.wiseview.ai/v1/companies/AAPL/value-chain" \
  -H "Authorization: Bearer $WISEVIEW_API_KEY"
```

```python
import os
import requests

response = requests.get(
    "https://api.wiseview.ai/v1/companies/AAPL/value-chain",
    headers={"Authorization": f"Bearer {os.environ['WISEVIEW_API_KEY']}"},
)
response.raise_for_status()
print(response.json())
```

```javascript
const response = await fetch("https://api.wiseview.ai/v1/companies/AAPL/value-chain", {
  headers: { "Authorization": `Bearer ${process.env.WISEVIEW_API_KEY}` },
});
if (!response.ok) throw new Error(`WiseView answered ${response.status}`);
console.log(await response.json());
```
