# Averitt Express Fuel Surcharge API

> Averitt Express LTL fuel surcharge rates via hidden JSON API — current week with DOE diesel price.

Averitt Express (SCAC: **AVRT**) publishes its LTL fuel surcharge through a hidden JSON endpoint used by the carrier's own web frontend. NexusFeed calls that endpoint directly, so the extraction is fast, reliable, and low-overhead — no browser rendering required. Averitt is routed through a residential proxy at the httpx layer because its origin is geography-sensitive.

| **Historical weeks available** | **Current week only** (upstream JSON endpoint returns only `/api/fuel_surcharges/current`) |
| **Extraction method**          | `api_mirror`                                                                               |

## Why the proxy matters

Averitt's fuel surcharge JSON API rejects traffic from certain cloud egress ranges, including Railway's EU region. NexusFeed routes Averitt httpx requests through a residential proxy to present a US origin. The proxy is transparent to callers of this API — you'll see a clean `api_mirror` response with a full `_verifiability` block either way.

## Example request

```bash theme={null}
curl "https://api.nexusfeed.dev/v1/ltl/fuel-surcharge?carriers=AVERITT&weeks=1" \
  -H "X-API-Key: YOUR_KEY"
```

## Example response

```json theme={null}
{
  "carrier": "AVERITT",
  "weeks": [
    {"effective_date": "2026-04-07", "fuel_surcharge_pct": 38.9, "doe_diesel_price_usd": 3.812}
  ],
  "_verifiability": {
    "source_timestamp": "2026-04-10T14:22:11Z",
    "extraction_confidence": 1.0,
    "raw_data_evidence_url": "https://www.averittexpress.com/api/fuel_surcharges/current",
    "extraction_method": "api_mirror",
    "data_freshness_ttl_seconds": 604800
  }
}
```

## Use cases

* Auditing Averitt LTL invoices in real time.
* Quoting southeastern lanes where Averitt is a preferred carrier.
* Pairing with [SEFL](/carriers/sefl) and [ODFL](/carriers/odfl) for multi-carrier southeast benchmarking.
