Affiliate data, by API and MCP

The same verified directory the site runs on, as a REST API and a remote MCP server. Query affiliate programs by category, network, recurring vs one-time, and a modelled value per referral. Every figure traces to the program's own affiliate page or its network listing.

Free key with a daily limit. The bulk dataset and MCP server are open and keyless.How we verify

Authentication

Get a key, send it as a Bearer header

The REST API requires an API key. Create a free key (a 100-request daily limit), then send it on every request:

curl "https://bestaffiliateprograms.cc/v1/programs?limit=3" \
  -H "Authorization: Bearer YOUR_API_KEY"

Each response returns your X-RateLimit-Remaining for the day. The keyless surfaces for AI engines and agents are the bulk dataset /affiliate-programs.json and the MCP server below.

Quick start

Query the REST API

The highest-paying recurring SaaS programs, ranked by modelled value per referral:

curl "https://bestaffiliateprograms.cc/v1/programs?category=saas&recurring=true&sort=value&limit=5" \
  -H "Authorization: Bearer YOUR_API_KEY"

A single program by slug:

curl "https://bestaffiliateprograms.cc/v1/programs/toptal" -H "Authorization: Bearer YOUR_API_KEY"

Endpoints

Method	Path	Description
GET	/v1/programs	List programs. Filters: category, network, recurring, confidence, min_value, q, sort, limit, offset.
GET	/v1/programs/{slug}	One program's full verified record.
GET	/v1/categories	Category facet with counts.
GET	/v1/networks	Network facet with counts.
GET	/v1/stats	Headline coverage + the verification note.
GET	/v1/openapi.json	The full OpenAPI 3.1 specification (no key required).
POST	/v1/mcp	Remote MCP server (Streamable HTTP), no key required: initialize, tools/list, tools/call.

The data endpoints require a key. q is a relevance search (the same ranking the site's board uses: it matches a program's name, description, category, and network); when q is set, results are ordered by relevance. Results are paginated (50 per page by default, up to 200) with a next URL. Unknown params are ignored, never an error. Full spec: /v1/openapi.json.

For agents

Remote MCP server (no key)

Connect an AI assistant or agent (Claude, Cursor, and any MCP client) directly to the directory. It is a remote Streamable-HTTP server, so there is nothing to install and no key: just add the URL.

https://bestaffiliateprograms.cc/v1/mcp

Client config (e.g. an MCP mcpServers block):

{
  "mcpServers": {
    "bestaffiliateprograms": {
      "url": "https://bestaffiliateprograms.cc/v1/mcp"
    }
  }
}

Tools: search_affiliate_programs, get_affiliate_program, list_categories, list_networks, get_directory_stats.

What the numbers mean

Honest by construction

modelledValuePerReferralUsd is a conservative MODEL of one paid referral from each program's published terms, not a guaranteed payout.
confidence: confirmed means the commission and cookie were read on the program's own affiliate page; network means they were read on a reputable network or aggregator listing.
Every record carries its sources and a lastVerified date. Nothing is invented.
Data is free to cite with attribution and a link back. Please do not present the compilation as your own or rebuild a competing catalogue from a bulk copy. The full catalog is also at /affiliate-programs.json; methodology at /methodology.
