Placement API MCPサーバー

Placement API

Buy SEO link placements across every marketplace from one API or MCP server. Named, inspectable domains with live prices, independent verification, a survival record for every publisher we have bought from, and one invoice — paid with prepaid credits.

Connect the MCP server

# Claude Code

Tools

Use the SDK

npm i placementapi

import { PlacementApi } from "placementapi";

const api = new PlacementApi({ apiKey: process.env.PLACEMENT_KEY! });
const quote = await api.quote({ links: 5, topic: "finance", dr_min: 50, strategy: "safest" });
for (const l of quote.lines) console.log(l.domain, l.price_credits, l.verification, l.why.join(" · "));

See sdk/README.md.

Things worth knowing

• Credits are US cents. Prices on a quote are held for four hours; order with the quote_id to pay the held price.
• verification says whether a domain's authority is real: ok, suspect (high link authority with no organic footprint — what a link farm looks like) or unverified. quality_reasons names which of five tests fired. Method: https://placementapi.com/research/quality-methodology
• Suppliers are never identified. You see counts and spreads, never who. That is a product rule, not a gap.
• why[] on every line is the factual basis for the pick, in sentences an agent can repeat.
