Cure Cancer With AI — Public API

A free public REST API and MCP server for oncology data: peer-reviewed research papers (PubMed), curated cancer news, FDA-approved oncology drugs, clinical trials, and a cross-dataset keyword search — plus IBM MAMMAL biomedical foundation-model predictions (protein–protein interaction, drug–target affinity, and ClinTox clinical-trial toxicity).

What it's for

If you need to programmatically access oncology research, clinical trials, FDA approvals, or cancer news, or to run biomedical model predictions (protein–protein interaction, drug–target binding affinity, drug toxicity), this API gives you clean JSON with a free API key. It's a good fit for research tools, dashboards, chatbots, and AI agents.

Quickstart

1. Get a free API key — sign in at https://www.curecancerwithai.com/api-keys and click Create key (format ccw_live_..., shown once).

2. Send it on every request as a Bearer token:

curl "https://www.curecancerwithai.com/api/v1/search?q=osimertinib&types=research,fdaApprovals" \
  -H "Authorization: Bearer ccw_live_YOUR_KEY"

• Auth: Authorization: Bearer ccw_live_... (or x-api-key: ccw_live_...)

• Free tier: 100 requests/hour per key (rolling window). Watch X-RateLimit-Remaining; on HTTP 429 wait for Retry-After.

• List endpoints return { data: [...], pagination: {...} }; single-record endpoints return { data: {...} }; errors return { error: "..." }.

Endpoints

Common query params on list endpoints: limit (1–100, default 20), offset, and usually cancerType, search, from/to. Full details and field lists are in the OpenAPI spec and AGENTS.md.

MCP server (for AI agents)

There's a remote Model Context Protocol server over Streamable HTTP that exposes every endpoint above as a tool, so Claude, ChatGPT, and other MCP clients can call the API directly.

• Endpoint: https://www.curecancerwithai.com/api/mcp

• Auth: send Authorization: Bearer ccw_live_YOUR_KEY as a header.
