Quickstart
Your first call is keyless. Three steps from curl to an agent with all 12 tools.
1. Call the API with nothing
The open tier serves a company's full current state without a key:
curl https://api.bixel.com/v1/companies/pinecone.io{
"data": {
"company": {
"name": "Pinecone",
"domain": "pinecone.io",
"slug": "pinecone",
"categories": ["vector-databases"]
},
"last_captured_at": "2026-07-14",
"jobs": { "active_postings": 3 },
"dimensions": {
"pricing": {
"count": 11,
"facts": [
{
"key": "pricing.model",
"value": "hybrid",
"provenance": "company_stated",
"as_of": "2026-07-13",
"source_url": "https://www.pinecone.io/pricing/"
}
]
}
}
}
}(Response truncated; the real payload carries all ten dimensions.)
Companies are identified by apex domain. If you only have a name, resolve it first:
curl "https://api.bixel.com/v1/search?q=pinecone"The change feed is also open, masked: you see that something changed and when, but values and summaries need a key.
curl "https://api.bixel.com/v1/changes?category=vector-databases&limit=3"{
"data": {
"events": [
{
"company": "pinecone.io",
"dimension": "features",
"fact_key": "features.agentic-retrieval",
"type": "feature_removed",
"significance": "high",
"detected_at": "2026-07-13",
"derivation": "confirmed",
"masked": true
}
]
}
}2. Add a free key to unmask
Sign in at bixel.com/account/keys and mint a key. Keys start with bx_ and are shown once; Bixel stores only a hash.
curl "https://api.bixel.com/v1/changes?category=vector-databases&limit=3" \
-H "Authorization: Bearer bx_your_key_here"Masked fields fill in: old_value, new_value, and a written summary per event, for the last 90 days of history — the full archive (back to 2020 for the deepest members) unlocks with Pro. The free key includes 1,000 credits per 30 days; see Authentication for how requests are weighted.
3. Point an agent at the MCP server
The MCP endpoint is https://api.bixel.com/mcp. In Claude, add it as a custom connector and sign in when prompted; tool calls work on every tier, the free account included. Key-header clients work too:
claude mcp add --transport http bixel https://api.bixel.com/mcp \
--header "Authorization: Bearer bx_your_key_here"The MCP guide covers the OAuth flow, client-by-client setup, and all 12 tools.
