Vestaron

Vestaron is an agricultural biotechnology company founded in 2005 and headquartered in Kalamazoo, Michigan, that develops peptide-based bioinsecticides derived from the venom of spiders and other venomous species. Its peptides deliver insecticidal modes of action that had never before been used for insect control — SPEAR, the first commercialised active ingredient, introduced IRAC Group 32, the first new neuromuscular mode of action since the diamides — and are effective on lepidopteran and sucking pests while remaining gentle on pollinators and beneficial insects. The commercial portfolio is SPEAR LEP, SPEAR RC, SPEAR T, BASIN FLEX, LEPROTEC and LEPROTEC WG, manufactured in partnership with ADM. The company has won the Crop Science Award and an EPA Green Chemistry Challenge award, and in 2024 became the first agriculture and food company inducted into the Global CleanTech 100 Hall of Fame. Vestaron publishes no developer program, no product API and no API documentation. The only machine-readable surfaces on vestaron.com are the WordPress REST content API (wp/v2), which is anonymously readable and serves the corporate newsroom, product and company pages and media library, and an OAuth-gated Model Context Protocol endpoint advertised through RFC 8414 and RFC 9728 metadata.

Vestaron publishes 9 APIs on the APIs.io network, including Comments API, Discovery API, Media API, and 6 more. Tagged areas include Company, Agriculture, AgTech, Biotechnology, and Crop Protection.

Vestaron’s developer surface includes product news, support, legal docs, YouTube channel, authentication, code examples, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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 github.com/api-evangelist/vestaron: open an issue to ask a question, or submit a pull request to add artifacts.

    is OAuth 2.1 authorization-code with mandatory PKCE (S256), a single `mcp` scope, public clients (token_endpoint_auth_methods
    none), refresh tokens and client-ID metadata documents. tools/list is authenticated: an anonymous JSON-RPC call returns
    HTTP 401 mcp_unauthorized, and the backing wp-abilities/v1 registry returns 401 rest_forbidden, so the live tool schemas
    require an authorized session and no tool list is asserted here.'
