This guide assumes you want one of two things: a live LTL fuel surcharge rate or a current ABC liquor license status. Both follow the same pattern — get a key, send one request, read the _verifiability block.

​
1. Get an API key

NexusFeed is provisioned through RapidAPI in the MVP phase. There are two separate listings — one per product. Subscribe to the one you need.

LTL Fuel Surcharge

ladourv/api/ltl-fuel-surcharge-api · $0.03 per request

ABC License Compliance

ladourv/api/abc-license-compliance-api · $0.05 per request
After subscribing, RapidAPI shows you an X-RapidAPI-Key on the listing page. That is your API key. It is also valid as X-API-Key when calling api.nexusfeed.dev directly.
You can subscribe to both listings with the same RapidAPI account. They bill independently.

​
2. Your first LTL fuel surcharge call

curl "https://api.nexusfeed.dev/v1/ltl/fuel-surcharge?carriers=ODFL&weeks=1" \
  -H "X-API-Key: YOUR_KEY"
Expected response shape: 
{
  "carrier": "ODFL",
  "weeks": [
    {
      "effective_date": "2026-04-07",
      "fuel_surcharge_pct": 42.3,
      "doe_diesel_price_usd": 3.812
    }
  ],
  "_verifiability": {
    "source_timestamp": "2026-04-10T14:22:11Z",
    "extraction_confidence": 1.0,
    "raw_data_evidence_url": "https://api.odfl.com/tools/fuel-history/v1.0/fuel-history.list",
    "extraction_method": "api_mirror",
    "data_freshness_ttl_seconds": 604800
  }
}
Always check _verifiability.extraction_confidence >= 0.90 before using a rate in a billing decision or invoice audit. Lower confidence means one or more required fields could not be extracted cleanly from the upstream source.
curl "https://api.nexusfeed.dev/v1/abc/search?state=CA&dba_name=TRADER%20JOE" \
  -H "X-API-Key: YOUR_KEY"
At least one of dba_name, owner_name, or address is required. Results are cached for 24 hours keyed on the query parameters.

​
4. Direct license lookup (already know the license number)

curl "https://api.nexusfeed.dev/v1/abc/license/47-123456?state=CA" \
  -H "X-API-Key: YOUR_KEY"
This is the precise version — one license number in, one record out. The _verifiability.raw_data_evidence_url in the response links directly to the state agency’s record so a human auditor can independently verify.
