CONNECT

How does an agent connect?

Over MCP, one config block and no install. Works with Claude Desktop, Claude Code, Cursor, Cline, and any MCP client:

{ "mcpServers": { "crustapi": { "command": "npx", "args": ["-y", "crustapi-mcp"], "env": { "CRUSTAPI_API_KEY": "key_live_xxxx" } } } }

Restart the client and the tools appear. Prefer raw HTTP? It is one GET, and the OpenAPI spec is machine-readable, so agents can discover it themselves. LangChain users: pip install langchain-crustapi.

AGENT PAYMENTS

Can the agent pay for itself?

Yes, for real. An agent with a wallet hits POST /v1/x402/topup with no key, gets back x402 payment requirements, pays in USDC, and receives a working, credit-loaded API key. No card, no human, no signup form. Proven end-to-end with a real on-chain payment.

THE RESPONSE

What does a response look like?

A real type=web call, trimmed. Nine organic results came back in 984 ms:

PRICING

How much does it cost?

One credit per successful search, however many results come back. A search that returns nothing is free, so a wandering agent never burns budget on dead ends. Maps bills per business returned instead.

Start with 3,000 free credits a month, no card. Paid packs run from 25,000 credits for $49 ($1.96 per 1,000) down to $0.40 per 1,000 at volume, and credits never expire, which matters when an agent's usage is bursty.

FAQ

Common questions

Yes, crustapi-mcp on npm. One npx config block, no install, and it works in Claude Desktop, Claude Code, Cursor, Cline, and any other MCP client. It is also listed in the official MCP registry.

x402 lets software pay for an API over HTTP. An agent with a USDC wallet calls our topup route, pays, and gets a working key back, with no human in the loop. Useful when an agent manages its own running costs.

Yes. langchain-crustapi is on PyPI and n8n-nodes-crustapi is on npm, both official. Everything else connects over MCP or plain HTTP with the OpenAPI spec.

Every call runs the search at request time. Nothing on this page or in the API is served from a stored crawl, which is the difference between grounding an agent in the web and grounding it in a snapshot.

We collect public, logged-out pages with no accounts and no fake profiles. Logged-out, public-only collection has repeatedly defeated computer-fraud and contract claims. Check your own use case with a lawyer.

3,000 credits every month, no card, across every surface including LinkedIn. Enough to build and test an agent end to end before you spend a dollar.
