# Harbinger (Harbinger Motors Inc.) > Harbinger Motors is an American commercial-vehicle manufacturer founded in July 2021 and based in > Garden Grove, California. It builds a purpose-designed medium-duty platform — Class 4-6 stripped > chassis in all-electric and plug-in hybrid range-extended form, the HC Series low-cab-forward cab > chassis, the Sevna cab chassis and a step van — around in-house motors, battery packs, power > electronics and vehicle software. Its Industria line packages the same drivetrain as off-grid and > jobsite power systems. Customers and partners named in its own newsroom include FedEx, THOR > Industries, Bimbo Bakeries USA, Panasonic Energy, Airstream, Frazer, Wabash and American > Rheinmetall. **Harbinger Motors publishes no API, no developer portal, no API documentation, no SDKs and no partner API.** It is a vehicle manufacturer, not a software vendor. This file was generated by API Evangelist, not by Harbinger Motors; the provider serves no `/llms.txt` of its own (`https://harbingermotors.com/llms.txt` -> 404) and no `/.well-known/` discovery surface of any kind (every path probed -> 404, verified against a control path). The one machine-readable interface the company exposes to the public is the WordPress REST content API behind its marketing site at `https://harbingermotors.com/wp-json`. It is anonymously readable, read-only for unauthenticated callers, unversioned as a contract, and carries no rate-limit signal, no caching signal, no status page and no support channel. Consume it defensively. ## APIs Base URL: `https://harbingermotors.com/wp-json` — no credentials required, no signup, no key. - [Posts API](https://harbingermotors.com/wp-json/wp/v2/posts): 34 newsroom items — press releases, funding rounds, partnerships, product launches, plus two fleet-operations articles. Newest post dated 2026-07-31. - [Pages API](https://harbingermotors.com/wp-json/wp/v2/pages): 35 pages. The product line hangs off page id 660 (`/our-products/`): plug-in hybrid chassis, electric chassis, step van, cab chassis, HC Series cab, Industria power system. Also Technology, Charging, Warranty, Incentives, TCO Calculator, Dealers, Sourcewell, Careers, Supplier Portal and the legal set. - [Events API](https://harbingermotors.com/wp-json/wp/v2/event): 7 trade shows and industry summits (ACT Expo 2026, Work Truck Week 2026, Government Fleet Expo, FedEx Forward Service Provider Summit). The only site-specific post type Harbinger registered. - [Media API](https://harbingermotors.com/wp-json/wp/v2/media): 624 assets. Filter `?mime_type=application/pdf` to reach the actual spec sheets and brochures — this is where the vehicle numbers live. - [Taxonomy API](https://harbingermotors.com/wp-json/wp/v2/categories): three categories — Press Release (id 1, 25 posts), News (id 2, 7), Blogs (id 18, 2). The `post_tag` taxonomy is registered but empty. - [Search API](https://harbingermotors.com/wp-json/wp/v2/search): cross-type keyword search over posts, pages and events. Branch on `subtype`, not `type`. - [Discovery API](https://harbingermotors.com/wp-json/): the route index — 362 routes across 14 namespaces, each with its argument schemas. This is the contract everything else here was derived from. - [oEmbed API](https://harbingermotors.com/wp-json/oembed/1.0/embed): oEmbed 1.0 rich descriptors for any site URL. The `description` field is the cleanest product summary available. - [SEO Metadata API](https://harbingermotors.com/wp-json/yoast/v1/get_head): rendered head metadata and the schema.org JSON-LD graph for any site URL. ## Specs None of these is published by Harbinger. Each is derived by API Evangelist from the server's own route index and HTTP OPTIONS schema documents on 2026-08-22. - openapi/harbinger-posts-api-openapi.yml - openapi/harbinger-pages-api-openapi.yml - openapi/harbinger-events-api-openapi.yml - openapi/harbinger-media-api-openapi.yml - openapi/harbinger-taxonomy-api-openapi.yml - openapi/harbinger-search-api-openapi.yml - openapi/harbinger-discovery-api-openapi.yml - openapi/harbinger-oembed-api-openapi.yml - openapi/harbinger-seo-api-openapi.yml ## How to call it - Pagination: `page`, `per_page` (default 10, max 100 — 999 returns 400), `offset`, `order`, `orderby`. Read `X-WP-Total` and `X-WP-TotalPages`; follow the RFC 8288 `Link` header. - Sparse fields: `_fields=id,slug,title,link` cuts a multi-kilobyte record to a few hundred bytes. - Relations: `_embed=1` inlines author, featured media and terms. This is the **only** way to read an author — `/wp/v2/users` returns 401 anonymously. - Errors: `{code, message, data:{status, params?}}`. Match on `code`, never `message`. Not RFC 9457. - `context=edit` returns 401. Stay on the default `context=view`. ## What is NOT here - **No vehicle, telematics, charging or diagnostics data.** The `/technology/` page markets integrated telematics, ELD integration and predictive maintenance; there is no public interface to any of it, and no OCPP, OCPI, ISO 15118, SAE J1939 or ATA/TMC surface exists. - **No structured product data.** Range, GVWR, payload and battery capacity are inside rendered HTML and PDF one-pagers, not fields. - **No structured event data.** The `event` type returns `acf: []`, so event dates, venues and cities are only inside rendered content. - **No writes.** Anonymous POST returns 401 `rest_cannot_create`; application passwords have no public issuance path. - **No MCP server, no A2A agent card, no GraphQL, no gRPC, no SOAP, no AsyncAPI, no webhooks.** All probed on 2026-08-22; all absent. - **No SDKs.** Nothing first-party on npm, PyPI or any other registry. - **No rate limits, no status page, no changelog, no deprecation policy, no SLA, no developer support channel.** ## Company - Website: https://harbingermotors.com/ - About: https://harbingermotors.com/our-company/ - Products: https://harbingermotors.com/our-products/ - Technology: https://harbingermotors.com/technology/ - Newsroom: https://harbingermotors.com/newsroom/ (RSS: https://harbingermotors.com/feed/) - Downloads (spec sheets, brochures): https://harbingermotors.com/downloads/ - Dealers: https://harbingermotors.com/dealers/ - Contact: https://harbingermotors.com/contact/ - Careers: https://harbingermotors.com/careers/ - Terms of Use: https://harbingermotors.com/legal/terms-of-use/ - Privacy: https://harbingermotors.com/legal/privacy/ - Harbinger Industries (power systems): https://harbinger.industries/ ## Provenance Third-party profile maintained by API Evangelist (https://apievangelist.com).
