AlphaPipeline

Pay-per-call ($0.005–$0.03 USDC) market/on-chain data API for AI agents and trading bots — no signup, no API key, no OAuth. Authenticate and pay in a single request via the x402 protocol (HTTP 402) on Base, or call it as a remote MCP server from Claude Desktop, Cursor, or any MCP client.

Why AlphaPipeline

AlphaPipeline is a machine-first data API. Every endpoint is metered per call using x402: a request without a payment header gets back a standard HTTP 402 response describing exactly how to pay (asset, amount, network, recipient). No account creation, no dashboard, no API key issuance — sign, retry the request with the payment attached, and you get the data back in the same request/response cycle.

It is also exposed as a remote MCP server (POST /mcp) so agent frameworks (Claude Desktop, Cursor, LangChain, CrewAI, and anything else that speaks MCP) can discover and call it with zero custom integration code.

• Discovery is always free. initialize and tools/list never require payment — browse the full tool catalog before you decide to pay.

• One tool is a permanent free onboarding endpoint (unlocks.dump_risk, see below) so an agent can verify connectivity, latency, and response schema before it starts paying for the rest.

• Settlement is Coinbase CDP (Developer Platform) Facilitator on Base mainnet (eip155:8453), asset USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).

The endpoints have not been reviewed by Coinbase — please ensure you trust them prior to sending funds.

Quickstart — Remote MCP

Add this to your MCP client's config (Claude Desktop claude_desktop_config.json, Cursor .cursor/mcp.json, or equivalent):

{
  "mcpServers": {
    "alphapipeline": {
      "url": "https://alphapipeline-eu.onrender.com/mcp"
    }
  }
}

tools/list works immediately with no payment. tools/call on a priced tool requires an x402-aware client that can sign and retry a payment (a wallet-holding bot/agent client — most stock chat UIs cannot pay automatically). See examples/ for a working Python client using the official x402 SDK.

Quickstart — Plain REST / x402

curl -s https://alphapipeline-eu.onrender.com/v1/market/kimchi-alert?symbol=BTC
# -> HTTP 402, payment terms in the `payment-required` response header (base64 JSON)
# sign a payment, retry with the PAYMENT-SIGNATURE header attached -> 200 + data

Note for client authors: this server speaks x402 v2 — the 402 response body is an empty {}; the actual payment terms (accepts array, price, asset, pay-to address) are base64-JSON in the payment-required response header, not the body. A client written against the older body-shaped convention will get an empty object with no error, not a loud failure. Decode the header instead.

Note on unlocks.dump_risk: it is intentionally free (no x402 payment required) as an onboarding tool. If a third-party discovery catalog (e.g. x402 Bazaar) still shows a stale non-zero price for it from before this change, treat this server's own / response and MCP tools/list output as the source of truth — they always reflect the live price.

Note on tool names: MCP tool names use a domain.tool_name dot-notation (e.g. market.kimchi_alert) so the tool list forms a navigable tree by domain. The REST paths under /v1/<domain>/... are unaffected by this and remain stable.

Tools / Endpoints

Every response is timestamped in both UTC and KST, and every priced endpoint's payment prompt reads "Paid in USDC on Base." so a human looking at the 402 screen in a browser isn't left guessing which chain's USDC to send.
