# Saia Fuel Surcharge API

> Current and historical Saia LTL Freight fuel surcharge rates including DOE diesel price — extracted from the carrier's public tariff table.

Saia LTL Freight (SCAC: **SAIA**) publishes its fuel surcharge schedule as a plain HTML table on `saia.com/tools-and-resources/fuel-surcharges`. The table includes the effective date, the DOE #2 diesel price, the LTL fuel surcharge percentage, and a truckload rate. NexusFeed parses the table in headless Chromium and normalizes the dates to ISO 8601.

## Carrier overview

| Field                          | Value                                     |
| ------------------------------ | ----------------------------------------- |
| **SCAC code**                  | SAIA                                      |
| **Full name**                  | Saia LTL Freight                          |
| **Headquarters**               | Johns Creek, GA                           |
| **Coverage**                   | National                                  |
| **DOE diesel price**           | Yes                                       |
| **Historical weeks available** | Full history published on the tariff page |
| **Extraction method**          | `playwright_dom`                          |
| **Cache TTL**                  | 7 days                                    |

## Why the URL matters

Saia's fuel surcharge page is at the **plural** path `/tools-and-resources/fuel-surcharges` — the singular form redirects to the carrier's homepage. A surprising number of scrapers target the wrong URL and get the home page HTML back, producing silent failures. NexusFeed uses the plural path and parses the well-formed table directly.

## Example request

<CodeGroup>
  ```bash curl theme={null}
  curl "https://api.nexusfeed.dev/v1/ltl/fuel-surcharge?carriers=SAIA&weeks=4" \
    -H "X-API-Key: YOUR_KEY"
  ```

  ```python Python theme={null}
  import httpx

  resp = httpx.get(
      "https://api.nexusfeed.dev/v1/ltl/fuel-surcharge",
      params={"carriers": "SAIA", "weeks": 4},
      headers={"X-API-Key": "YOUR_KEY"},
  )
  data = resp.json()
  print("Current Saia LTL fuel surcharge:", data["weeks"][0]["fuel_surcharge_pct"], "%")
  ```
</CodeGroup>

## Example response

```json theme={null}
{
  "carrier": "SAIA",
  "weeks": [
    {"effective_date": "2026-04-07", "fuel_surcharge_pct": 40.1, "doe_diesel_price_usd": 3.812}
  ],
  "_verifiability": {
    "source_timestamp": "2026-04-10T14:22:11Z",
    "extraction_confidence": 1.0,
    "raw_data_evidence_url": "https://www.saia.com/tools-and-resources/fuel-surcharges",
    "extraction_method": "playwright_dom",
    "data_freshness_ttl_seconds": 604800
  }
}
```

## Use cases

* Audit Saia LTL invoices against the published weekly rate.
* Compare Saia's fuel surcharge to [ODFL](/carriers/odfl), [Estes](/carriers/estes), and [XPO](/carriers/xpo) when picking a carrier for a given shipment.
* Track week-over-week trends alongside DOE #2 diesel prices for procurement planning.
