What is APIbase?

Production MCP server that gives AI agents access to 789 real-world API tools through a single endpoint. Agents connect once to https://apibase.pro/mcp and can search flights, get stock quotes, check weather and tides, forecast ocean waves and swell, query US Census and CDC health data, search ML models on HuggingFace, look up World Bank indicators, query UN SDG development goals data, track streamflow from USGS stations, search 7M+ CS papers on DBLP, generate images, send emails, decode VINs, look up chemical compounds, scan npm/PyPI vulnerabilities, search NIST NVD CVE records, find EV chargers, estimate solar PV output, search art at the Met Museum, look up Dota 2 match stats, get decoded aviation METAR/TAF, look up parsed NOTAMs and PIREPs, search FDA medical device recalls and 510(k) clearances, batch multiple calls, track usage analytics — and 869 tools across 30+ categories.

Built for AI agents, not humans. Auto-registration, zero setup, pay-per-call via x402 USDC micropayments on Base or MPP (Machine Payments Protocol) on Tempo.

Quick Start (30 seconds)

Claude Desktop / Cursor / Windsurf

{
  "mcpServers": {
    "apibase": {
      "url": "https://apibase.pro/mcp"
    }
  }
}

Multi-server setup (recommended)

Combine APIbase (real-world APIs) with Playwright (browser) and Context7 (docs):

{
  "mcpServers": {
    "apibase": { "url": "https://apibase.pro/mcp" },
    "playwright": { "command": "npx", "args": ["-y", "@playwright/mcp"] },
    "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp"] }
  }
}

With Base MCP (pay from your Base Account)

Base MCP launched May 2026 with native x402 support. APIbase is x402-native on Base mainnet — the two pair cleanly. Base MCP signs payments from your Base Account; APIbase serves 600+ external API tools.

{
  "mcpServers": {
    "base-mcp": { "url": "https://mcp.base.org" },
    "apibase":  { "url": "https://apibase.pro/mcp" }
  }
}

Zero API-key management (Base Account handles auth + signing), zero per-provider signup (APIbase aggregates 250 providers). Full guide: apibase.pro/frameworks#base-mcp.

Via npm (stdio bridge)

{
  "mcpServers": {
    "apibase": {
      "command": "npx",
      "args": ["-y", "apibase-mcp-client"]
    }
  }
}

Platform Features

Usage Analytics (Free)

Track your API usage — total calls, cost, cache hit rate, latency, and per-tool breakdown.

# Usage summary
curl -X POST https://apibase.pro/api/v1/tools/account.usage/call \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"period": "7d"}'

# Per-tool breakdown
curl -X POST https://apibase.pro/api/v1/tools/account.tools/call \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"sort": "cost", "limit": 10}'

# Time series (hourly/daily buckets)
curl -X POST https://apibase.pro/api/v1/tools/account.timeseries/call \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"period": "30d", "granularity": "day"}'

Tool Quality Index (Free)

Check tool reliability before calling — uptime, p50/p95 latency, error rate. Updated every 10 minutes.

# Quality metrics for a specific tool
curl -X POST https://apibase.pro/api/v1/tools/platform.tool_quality/call \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"tool_id": "crypto.get_price"}'

# Rankings — find the most reliable tools
curl -X POST https://apibase.pro/api/v1/tools/platform.tool_rankings/call \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"sort": "uptime", "limit": 20}'

Batch API (Free wrapper)

Execute up to 20 tool calls in parallel with a single request. Each sub-call runs the full pipeline independently. You pay only for individual tool calls.

# Via MCP tool
curl -X POST https://apibase.pro/api/v1/tools/platform.call_batch/call \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"calls": [
    {"tool_id": "crypto.get_price", "params": {"coin": "bitcoin"}},
    {"tool_id": "finance.exchange_rates", "params": {"from": "USD", "to": "EUR"}},
    {"tool_id": "country.by_code", "params": {"code": "US"}}
  ]}'

# Via REST endpoint
curl -X POST https://apibase.pro/api/v1/tools/call_batch \
  -H "Authorization: Bearer ak_live_..." \
  -d '{"calls": [...], "max_parallel": 10}'

Predictive Pre-fetching

When an agent calls a tool, the platform can automatically pre-fetch related data into cache. For example, a flight search pre-fetches exchange rates for the destination currency — so when the agent asks for rates next, it's an instant cache hit.

• Fire-and-forget: does not slow down the original response
• Controlled by PREFETCH_ENABLED env var (disabled by default)
• Rules: flight search → exchange rates, real estate → walk score,
