Fluid Truck

Fluid Truck was a Denver, Colorado peer-to-peer commercial vehicle sharing platform founded in 2016 by James Eberhard and Jenifer Snyder, often described as "the Zipcar of commercial vehicles". It operated an app-based, self-service rental marketplace for cargo vans, box trucks and flatbeds across roughly 400 cities in 32 US states, and ran the Fluid Vehicle Investor Program (FVIP) through which individuals and small businesses bought fleets that Fluid managed and rented out. The company raised over $80 million in venture funding, filed for Chapter 11 bankruptcy in Delaware in October 2024 after an $20.6 million cash loss in 2023, sold substantially all assets to Kingbee Rentals in December 2024, and the case converted to Chapter 7 liquidation in September 2025. The company is wound down: no developer program, API documentation, or machine-readable contract was ever published, and its own web properties no longer serve a valid TLS certificate.

Fluid Truck is profiled on the APIs.io network. Tagged areas include Company, Transportation, Logistics, Vehicle Rental, and Fleet Management.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

13 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Developer Ergonomics scores 0.0 — up to +20.0 composite points
Access Clarity scores 0.0 — up to +20.0 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/fluid-truck/apis.yml: open an issue on github.com/api-evangelist/fluid-truck to ask a question or point us at an artifact you publish.

  detail: Fluid Truck is wound down — Chapter 11 in Delaware October 2024, assets sold to Kingbee Rentals December 2024, converted
    to Chapter 7 liquidation September 2025 — and fluidtruck.com now fails the TLS handshake outright on every request while
    app.fluidtruck.com returns Vercel DEPLOYMENT_NOT_FOUND, so there is no surface left to read and no archived evidence a
    developer program ever existed.
