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 is listed with 2 APIs on the APIs.io network. 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 27 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 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
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
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

    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.'
