AI visibility API and MCP server

Read your Glossy Data data from code or from an AI assistant. Every rate comes with its sample size and interval, the same numbers as the dashboard. Reads cost no credits.

Overview

REST API

Live

24 endpoints under https://www.glossydata.com/api/v1: projects, visibility per engine, share of voice, competitors, citations, answers, prompts and audits. JSON in, JSON out. 2 are marked Coming soon below.

MCP server

Live

9 tools for Claude, Cursor and any MCP client at https://www.glossydata.com/mcp. Tools run the same code as the REST API, so scopes, statistics and credit rules match.

Every success response is { data, meta }. meta.methodology names the method version (honest-score-v2); rates carry n, k and a 95% ci. How the numbers are computed: methodology.

Authentication

Sign in, then open Settings → API keys in your workspace. Owners and admins can create, rotate and revoke keys.
Name the key, choose its scopes and an expiry (30 days, 90 days, 1 year, Never). The secret starts with slk_ and is shown once. Keys are stored hashed.
Send it on every request as a bearer token: Authorization: Bearer slk_…

Check your key · Terminal

export GLOSSY_DATA_API_KEY="slk_your_key"

curl https://www.glossydata.com/api/v1/me \
  -H "Authorization: Bearer $GLOSSY_DATA_API_KEY"

Visibility for one project, last 28 days · Terminal

curl "https://www.glossydata.com/api/v1/projects/PROJECT_ID/metrics?engines=chatgpt,perplexity" \
  -H "Authorization: Bearer $GLOSSY_DATA_API_KEY"

Keep the key in an environment variable such as GLOSSY_DATA_API_KEY, never in client-side code. Browser writes from other origins are refused.

Scopes

Scope	Allows	Type
`read:metrics`	Projects, visibility, share of voice, competitors, citations, agent traffic.	Read
`read:answers`	Full answer text and receipts.	Read
`write:prompts`	Add, edit and archive prompts. Credit-checked and audit-logged. Plans with API write access.	Write
`run:audits`	Start audits from the API or MCP. Uses credits from your pool. Plans with API write access.	Write

Rotation and revocation

Rotate issues a new secret with the same name and scopes, and the old secret stops working at once. Revoke a key and it never verifies again; its last-used history stays in the audit trail. Update your environment variable, then rotate.

MCP authentication

The MCP server takes the same API key, sent as a bearer token in the Authorization header. There is no OAuth sign-in step: paste a key into your client's config. A request without a key gets 401 with a WWW-Authenticate header that points to the protected-resource metadata (RFC 9728). MCP keys need read:metrics; tools that need other scopes appear only when the key has them.

Rate limits and plan access

Limits are per key, per minute. REST responses carry x-ratelimit-limit; over the limit you get 429 rate_limited, so wait and retry. A short per-second burst guard also applies.

Plans without write scopes get read-only keys: write:prompts and run:audits are refused with 403. Prompt writes are credit-checked and audits use credits from your pool. Compare plans

MCP quickstart

Server URL https://www.glossydata.com/mcp. Streamable HTTP, stateless: clients send JSON-RPC with POST. Create a key with read:metrics (add read:answers for full answer text), then paste it below in place of slk_your_key.

Claude Desktop reads local servers from its config file, so the snippet runs the open-source mcp-remote bridge (needs Node.js) to reach the HTTP server. Restart the client after editing its config.
