# Health



## OpenAPI

````yaml https://api.nexusfeed.dev/openapi.json get /health
openapi: 3.1.0
info:
  title: B2B Agentic Arbitrage Hub
  description: >-
    Real-time LTL freight carrier fuel surcharge rates and ABC liquor license
    compliance records, served as agent-ready JSON with verifiability metadata.
    Built for AI agents that need authoritative B2B data — not raw HTML
    scraping.


    ## Products

    - **LTL Fuel Surcharge** (`/v1/ltl`): 6 carriers (ODFL, Saia, Estes, ABF,
    R+L, TForce), weekly rates, DOE diesel price, up to 5 years of history

    - **ABC License Compliance** (`/v1/abc`): CA, TX, NY, FL — license status,
    expiration, and suspension records


    ## Authentication

    All endpoints require an `X-API-Key` header. Contact `ops@nexusfeed.dev` to
    obtain an API key.


    ## Verifiability

    Every response includes a `_verifiability` block with `source_timestamp`,
    `extraction_confidence`, `raw_data_evidence_url`, `extraction_method`, and
    `data_freshness_ttl_seconds` — enabling agents to cite provenance and assess
    staleness.
