What Carbonmark (BYOK) is for

Carbonmark (BYOK) lets an AI assistant read your own Carbonmark data through the Carbonmark API with a key you supply (Carbonmark API key (a free sandbox key works for reads)). Read-only: 6 tools (list_countries, list_vintages, list_methodology_categories, search_projects_by_text, filter_projects, get_project). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to v20.api.carbonmark.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Carbonmark. Carbonmark and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which countries have carbon projects on Carbonmark?"
• "Which carbon credit vintages are available?"
• "What methodology categories do carbon projects fall into?"
• "Find carbon projects about REDD+"
• "Which renewable energy projects in India have a 2012 vintage?"
• "Show details of carbon project VCS-274"

What it does

• list_countries: List the country values that can be used to filter carbon projects.
• list_vintages: List the vintage years that can be used to filter carbon projects.
• list_methodology_categories: List the methodology categories (for example Forestry, Renewable Energy, Blue Carbon) that can be used to filter carbon projects.
• search_projects_by_text: Search carbon projects by a text string matched against project name and description, for example 'REDD+'.
• filter_projects: Find carbon projects filtered by country, methodology category and vintage (use the list tools for valid values), with registry, supply stats and price.
• get_project: Get one carbon project by its key (registry and project id, for example VCS-274): registry link, methodologies, vintages, supply stats, price and sustainable development goals.

BYOK key

You bring your own Carbonmark Carbonmark API key (a free sandbox key works for reads) (https://developers.carbonmark.com/dashboard/keys). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to v20.api.carbonmark.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://docs.carbonmark.com/carbonmark-api/explore-carbon-projects (the API this connector calls, with a BYOK key)

Live from the Carbonmark API (v20.api.carbonmark.com) with a BYOK key; documentation: https://docs.carbonmark.com/carbonmark-api/explore-carbon-projects. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Carbonmark. Carbonmark and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Carbonmark account.

Carbonmark (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Carbonmark (BYOK) is. Carbonmark (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Carbonmark data: Discover carbon credit projects by country, vintage, methodology category or text, with registry, supply and price, using your own Carbonmark API key. You bring your own Carbonmark Carbonmark API key (a free sandbox key works for reads); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Carbonmark call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to v20.api.carbonmark.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Carbonmark rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Carbonmark receives. The request we make on your behalf, including the key and the arguments, under Carbonmark's own terms and privacy policy. Carbonmark acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Carbonmark gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Carbonmark data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Carbonmark (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Carbonmark at any time to end all access.

Children. Carbonmark (BYOK) is a general-audience service operated by the adult using the assistant, under Carbonmark's own age rules.

Changes. We will post changes here with a new effective date.
