Clickwise Affiliate Network

Clickwise API: products by GTIN, tracked affiliate links, MCP

Clickwise is an affiliate network with an API built for developers and AI agents. Search product feeds with GTINs from the networks, get product links tracked to you, find and join affiliate programs, and pull your conversions. Use it over REST, from an AI agent through MCP, or from HasOffers-compatible tools.

This repo gets you from zero to a working call: quickstarts, thin clients, MCP configs and a deployable affiliate store.

1. First call, no key

# How big is the catalog right now?
curl -s https://partners.clickwise.net/api/v1/public/catalog-stats/

# Sample products in one market (DE, ES, GB, PT, SE, FR, US); no links without a key
curl -s "https://partners.clickwise.net/api/v1/public/catalog-sample/?country=DE"

# Ask the MCP server which programs fit your site
curl -s https://partners.clickwise.net/api/v1/mcp \
  -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"find_affiliate_programs","arguments":{"topic":"sneakers","country":"ES","channel":"site"}}}'

2. Get your key

Request a publisher API key at https://partners.clickwise.net/developers/. Put it in an environment variable and keep it on your server:

export CLICKWISE_API_KEY=...   # never commit it, never ship it to a browser

3. First call with your key

# Who am I, what can this key do, what are my limits?
curl -s https://partners.clickwise.net/api/v1/publisher/me/ -H "X-API-Key: $CLICKWISE_API_KEY"

# Price, stock and YOUR tracked link for up to 100 GTINs
curl -s --get https://partners.clickwise.net/api/v1/publisher/products/lookup/ \
  -H "X-API-Key: $CLICKWISE_API_KEY" \
  --data-urlencode 'gtins=4006381333931,5901234123457' --data-urlencode 'country=DE'

# Search by title in one market
curl -s --get https://partners.clickwise.net/api/v1/publisher/products/ \
  -H "X-API-Key: $CLICKWISE_API_KEY" \
  --data-urlencode 'q=running shoes' --data-urlencode 'country=ES' --data-urlencode 'limit=20'

Each product comes back as {"gtin", "title", "price", "currency", "image", "url", "merchant", "availability", ...}. url is your tracked link: publish it exactly as returned.

Runnable versions of steps 1 and 3: quickstart/curl.sh · quickstart/quickstart.mjs (Node 18+) · quickstart/quickstart.py (Python 3.8+). No dependencies.

4. Use it from an AI agent (MCP)

Remote MCP server (Streamable HTTP): https://partners.clickwise.net/api/v1/mcp, listed in the official MCP Registry as net.clickwise/mcp. 19 tools; the key is optional (program discovery, deals and catalog stats work without it).

claude mcp add --transport http clickwise https://partners.clickwise.net/api/v1/mcp --header "X-API-Key: $CLICKWISE_API_KEY"

Configs for Claude Code, Cursor, Claude Desktop, VS Code and n8n, plus the tool list, in mcp/.

Earn commission from your AI assistant (product search, sub-IDs and signed postbacks): quickstart/monetize-agent.md.

5. Ship an affiliate store

templates/affiliate-store: a Next.js storefront that reads products by GTIN, shows live prices and publishes your tracked links. It deploys without a key in preview mode.

Building with Lovable, Bolt or v0? Paste templates/affiliate-store/PROMPT.md.

Running your own app or SaaS? Paste templates/merchant-tracking/PROMPT.md into Lovable, Bolt or v0 to add Clickwise sales tracking with Stripe, Lemon Squeezy or the conversions API.

6. Clients

Thin, dependency-free clients generated from the OpenAPI, one method per operation:

• TypeScript: clients/typescript/clickwise.ts (copy one file; Node, Bun, Deno, edge).
• Python: clients/python (pip install "git+https://github.com/softdevfz/clickwise-api#subdirectory=clients/python").

const cw = new Clickwise(); // CLICKWISE_API_KEY
const { products } = await cw.lookupProducts({ gtins: "4006381333931", country: "DE" });

What the API covers

One error shape ({"error": {"code", "message", "status", "request_id"}}), RateLimit-* headers on every response, Retry-After on 429, Idempotency-Key on POST, X-Request-Id everywhere. Changes inside v1 are additive.

Rules of the road

• Keep the key on your server. A key acts only for its own account and never has admin access.
• Publish product and tracking links exactly as returned, and disclose affiliate relationships (rel="sponsored" on links plus a visible disclosure).
• Refresh prices at least every 48 hours; hide products a lookup no longer returns.
• Honour rate limits: back off on 429 using Retry-After.
