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 APIs 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.
CarbonFarm’s developer surface includes engineering blog, support, authentication, and 17 more developer resources.
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.
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/carbonfarm: open an issue to ask a question, or submit a pull request to add artifacts.

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.

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
— a host found by following the image URLs on carbonfarm.tech and by DNS enumeration after crt.sh returned 502. The rice
MRV product API remains gated behind an Auth0 organization login at app.carbonfarm.tech, which 301s every path.'
