Apihubio tools (9, 2 write)

write = sends, deletes, buys or posts
  • apihub_balanceFree

    Read-only. Returns your current APIHub credit balance (in microdollars and USD), total lifetime spending (microdollars and USD), and total completed request count. Requires a valid API key. Use before apihub_call or apihub_call_external to confirm sufficient funds for a paid request, or periodically to audit usage. Does not modify state, send payments, or call upstream APIs; for top-ups use apihub_topup.

  • apihub_callwrite actionFree

    Sends payment. Calls a paid endpoint on an onboarded APIHub service. Debits the endpoint's price from your credit balance and forwards the request to the upstream provider. Returns an object with the upstream response body, HTTP status, and credits_charged_microdollars. Requires a valid API key and sufficient credit balance; if balance is insufficient the call returns a 402 with payment requirements (use apihub_topup to add credits, apihub_balance to check). Use this for services already onboarded to APIHub (find slugs via apihub_search or apihub_list_services); use apihub_call_external for arbitrary x402 URLs not onboarded here, or apihub_read_content for content gateways.

  • apihub_call_externalFree

    Call an external x402-protected URL (any provider in the marketplace or any x402 API). APIHub pays the provider on your behalf using the platform wallet and debits your credit balance for the exact amount. No wallet or gas required.

  • apihub_get_serviceFree

    Get full details for a specific API service including all endpoints, schemas, and pricing.

  • apihub_list_servicesFree

    Read-only. Lists onboarded APIHub services alphabetically, returning each service's slug, name, description, category, provider, endpoint count, and lowest per-endpoint price in microdollars. No authentication required. Use this to browse the full onboarded catalog when you don't have a specific capability in mind; prefer apihub_search when filtering by query, category, or price. Does not include external x402 APIs (use apihub_search_external for those) and does not return endpoint-level details (use apihub_get_service for that).

  • apihub_read_contentFree

    Read web content through a paid content gateway. Returns clean, structured text extracted from the URL. Use this for content services (service_type = 'content').

  • apihub_searchFree

    Read-only. Searches onboarded APIHub services by free-text query, with optional category, price, and type filters. Returns up to 10 matches ranked by uptime and endpoint count, each with slug, description, endpoints array, min price in microdollars, provider name, and quality score. No authentication required. Use this when you need to find an API by capability; use apihub_list_services to browse without a query, apihub_search_external to include the external x402 catalog, or apihub_get_service when you already know a slug. Does not call any upstream API or debit credits.

  • apihub_search_externalFree

    Search external x402-protected APIs (not operated by APIHub, but callable via credits). Returns listings with endpoint counts, prices, and on-chain activity.

  • apihub_topupwrite actionFree

    Purchase APIHub credits via x402 (USDC on Base). Returns payment instructions including a web URL for browser-based payment, a CLI command, and raw x402 requirements for agents with wallet support. Credits are added to your account instantly once payment confirms on-chain.

APIHub MCP Server

MCP server for APIHub — discover and call paid APIs with USDC credits. No wallet, no gas, no per-provider SDKs.

  • Hosted endpoint: https://mcp.apihub.io/mcp
  • Transport: Streamable HTTP
  • Protocol version: 2025-03-26
  • Auth: Bearer token (get a free key at apihub.io)

## Tools

## Quick start

### Claude Desktop / Cursor / Codex

Add to your MCP config:

{
    "mcpServers": {
      "apihub": {
        "url": "https://mcp.apihub.io/mcp",
        "headers": {
          "Authorization": "Bearer ahk_your_api_key"
        }
      }
    }
  }

### APIHub CLI

npx @apihubio/cli install    # writes the MCP config for you
  npx @apihubio/cli register   # get an API key
  npx @apihubio/cli topup 10   # fund with $10 USDC

## Why credits instead of per-call x402

  • Gasless: pay on-chain once when topping up, not per request
  • Walletless: no USDC, no EIP-3009 signing, no gas
  • Works in any MCP client: just a Bearer token header
  • Instant: D1 debit at the edge, no block confirmations per call
