Aventon

Aventon is a consumer electric bicycle (e-bike) manufacturer headquartered in Brea, California. Founded in 2012 and originally known for fixed-gear and track bikes, the company pivoted to electric bikes and is now one of the larger direct-to-consumer e-bike brands in the United States, with a lineup that spans commuter, fat-tire, lightweight, folding, cargo, and mountain e-bikes sold online and through a dealer network. Aventon operates no traditional public developer API of its own, but its Shopify-powered storefront at aventon.com natively exposes agent-facing commerce surfaces: a published /llms.txt, Shopify Customer Account OpenID Connect discovery, and a live Universal Commerce Protocol (UCP) MCP endpoint for agent-driven catalog search, cart, and checkout.

Aventon is listed with 1 API on the APIs.io network. Tagged areas include Company, Consumer, Electric Bikes, E-Commerce, and Retail.

Aventon’s developer surface includes engineering blog, authentication, and 10 more developer resources.

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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

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/aventon/apis.yml: open an issue on github.com/api-evangelist/aventon to ask a question or point us at an artifact you publish.
