What your agent can do

From web search and document generation to data conversion and validation. A sample of what's available.

Search & Research

Search the web, pull news on any topic, or extract metadata from a URL.

/tools/search/tools/news/tools/extract-url-metadata

Documents & Files

Generate PDFs from HTML, convert Markdown to a document, or fill a template.

/tools/html-to-pdf/tools/markdown-to-html/tools/fill-template

Media & Graphics

/tools/csv-to-json/tools/encode/tools/slugify

Finance & Time

Convert currencies at live rates, parse date strings, or translate between timezones.

/tools/currency-convert/tools/date-parse/tools/timezone-convert

Validation

Validate email addresses, check if URLs are reachable, or verify phone number formats.

/tools/validate-email/tools/validate-url/tools/validate-phone

Code & Dev

Format code, minify CSS or JS, or validate JSON against a schema.

/tools/format-code/tools/minify/tools/json-validate

Two ways to connect

Call any endpoint directly over HTTP. Or configure an MCP client once and your agent auto-discovers every available tool with no additional setup required.

via REST API

curl -X POST https://api.bigapi.ai/tools/search \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "Q3 2025 EV sales data", "limit": 5}'

via MCP — agent discovers all tools

// claude_desktop_config.json
// Your agent auto-discovers every available tool.
{
  "mcpServers": {
    "bigapi": {
      "url": "https://api.bigapi.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Sample endpoints

Every endpoint accepts JSON and returns JSON. Authenticated with X-API-Key.

How it works

Three steps and you're making API calls.

Create an account

Takes under a minute. Your account is ready immediately.

Get an API key

Generate a named key from your dashboard. Pass it as the X-API-Key header on every request.

Start calling tools

Hit any /tools/* endpoint over HTTP, or point an MCP-compatible client at https://api.bigapi.ai/mcp and it will auto-discover every available tool.

Pricing

Straightforward pricing. No seat fees, no per-endpoint fees.
