CarbonFarm Technology is a French climate-tech company (registered in Nanterre, SIREN 912160389) that uses satellite imagery and proprietary machine-learning models to monitor, measure and verify greenhouse-gas reductions in rice production. Rice accounts for roughly 12% of global methane emissions, and practices such as Alternate Wetting and Drying can cut paddy methane substantially — but conventional MRV depends on self-declared practices recorded in paper logbooks, which is expensive to collect from smallholders and open to fraud. CarbonFarm detects water-management and straw-management practices remotely at paddy level, estimates baseline and project emissions with validated models, and verifies additionality, at a fraction of the cost of ground-based MRV. Customers and partners named publicly include Mars Food, Tilda, Beneo, Amru Rice, Vida Energy, Fortune Rice, Ostrom Climate, Core Carbon X, the Sustainable Rice Platform, UNDP, Danone, Rikolto, Cornell University, IRRI and Regrow Ag. CarbonFarm operates no developer program: there is no developer portal, API reference, SDK or public API product, and the client platform sits behind an Auth0 organization login. The one machine-readable contract it publishes is the Directus headless CMS behind its marketing website.
CarbonFarm publishes 6 API contracts indexed on the APIs.io network, including Assets API, Authentication API, Files API, and 3 more. Tagged areas include Company, Climate Tech, Carbon Credits, Agriculture, and MRV.
The CarbonFarm catalog on APIs.io includes 1 Spectral governance ruleset.
CarbonFarm’s developer surface includes engineering blog, support, authentication, and 17 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 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/.

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility+6 pts — a reversal operation in the contract, graded up when a window is documented too
5 more unmet checks in the Agent Readiness table above.

The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
All data within the platform is private by default. The public role can be configured to expose data without authentication, or you can pass an access token to the API to access...
Access to where Directus runs. Allows you to make sure your server has everything needed to run the platform, and check what kind of latency we're dealing with.
Overlays applied on top of this provider's contracts. Each card says who wrote it: a document the provider publishes, or one API Evangelist derived or generated.

x-pointers-deliberately-withheld:
note: These artifacts exist on disk or were probed, but no canonical pointer is emitted because the pointer would assert
something CarbonFarm does not publish. Recorded so a later pass does not "fix" the omission.
withheld:
- type: MCPServer
reason: mcp/carbonfarm-mcp.yml is a DERIVED candidate with deployment.mode = none. CarbonFarm ships no hosted endpoint
and no stdio package.
- type: AgentCard
reason: /.well-known/agent-card.json and /.well-known/agent.json return 404 or 301 on every host. Never generated.
- type: SecurityTxt
reason: No security.txt on any host (404 everywhere).
- type: Idempotency
reason: Zero idempotency support — no Idempotency-Key on any of the 14 operations, no "idempoten" match in the spec.
- type: Compliance
reason: No certifications, no compliance page, no trust center. A privacy policy is not a compliance program.
- type: TrustCenter
reason: probe-security-programs.py returned trust=none.
- type: Security
reason: No vulnerability disclosure policy, no bug bounty, no security@ contact published. probe returned vdp=none.
- type: StatusPage
reason: No status page. carbonfarm.statuspage.io is unclaimed and 302s to statuspage.io itself.
- type: Deprecation
reason: No deprecation policy, no Sunset/Deprecation header, no API versioning scheme at all.
- type: ChangeLog
reason: carbonfarm.tech/posts is company news, not an API changelog. Wired as Blog.
- type: SDKs
reason: No first-party client library in any registry — npm, PyPI, RubyGems and crates.io all return nothing for "carbonfarm".
- type: Packages
reason: Same — no packages exist to catalogue.
- type: AsyncAPI
reason: No AsyncAPI published. GraphQL subscriptions exist in the SDL and are recorded there as evidence, not promoted
to an event contract.
- type: Webhooks
reason: No webhooks documented anywhere.
- type: Pricing
reason: No pricing page (/pricing, /plans, /price all 404).
- type: TermsOfService
reason: No terms of service published; the /legal page carries a privacy policy and a stakeholder consultation document
only.
- type: SignUp
reason: No self-serve sign-up (/signup, /register 404). Login is wired instead.
- type: Documentation
reason: No documentation of any kind exists.
- type: DeveloperPortal
reason: /developers and /api return 404. No developer portal.
- type: APIReference
reason: No API reference exists.
- type: GettingStarted
reason: No getting-started or quickstart page.
- type: Roadmap
reason: No public roadmap.
- type: Postman
reason: No public Postman collection or workspace found.
- type: Sandbox
reason: No sandbox, test mode, or test credentials published.
- type: CLI
reason: No first-party CLI.
- type: OAuthScopes
reason: The Auth0 tenant advertises only the default OIDC claim scopes, not an API permission model, and /.well-known/oauth-protected-resource
is 404. Recorded inside authentication/ instead of forcing an empty scopes artifact.

detail: 'STEP 0b contract discovery beat the marketing site. A first-round "no spec" verdict would have been wrong: a live
OpenAPI 3.0.1 and a full GraphQL SDL are published anonymously by CarbonFarm''s Directus CMS at cms.int.carbonfarm.app

MRV product API remains gated behind an Auth0 organization login at app.carbonfarm.tech, which 301s every path.'
