3 Practical Utility APIs for AI Agents: Document Conversion, Cryptographic Hashing, and More

#mcp #ai #api #webdev

If you're building AI agent pipelines, you eventually hit the same pattern: you need a small, boring utility that's annoying to self-host. Convert a DOCX to PDF. Hash a string. Read a file from GitHub. None of these are core to your product — but every agent workflow needs them eventually.

IteraTools now covers all of these with 48 pay-per-use API endpoints. This post covers the three most recently added utility tools.

1. Document Format Conversion — POST /document/convert

Convert documents between formats with a single API call:

  • DOCX/PPTX → PDF (LibreOffice)
  • Markdown → HTML or PDF (Pandoc)
  • HTML → PDF
  • PDF → DOCX

Price: $0.003/conversion

Example — Convert Markdown to HTML:

curl -X POST https://api.iteratools.com/document/convert \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "# Hello\n\nThis is **bold** text.",
    "from_format": "md",
    "to_format": "html"
  }'
Enter fullscreen mode Exit fullscreen mode

Response:

{
  "success": true,
  "url": "https://cdn.iteratools.com/docs/abc123.html",
  "format": "html",
  "size_bytes": 312
}
Enter fullscreen mode Exit fullscreen mode

Use cases for AI agents:

  • Agent generates a markdown report → convert to PDF for delivery
  • User uploads a DOCX → extract content for analysis
  • Generate PDF invoices from HTML templates

Pass either a url (public URL to the document) or content (inline text or base64 for binary formats). The from_format and to_format fields are required.

2. Cryptographic Hash Generation — POST /hash

Generate hashes of any text using standard algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512.

Price: $0.001/call

This runs entirely on Node.js native crypto — no external API, instant response, zero external cost.

Example:

curl -X POST https://api.iteratools.com/hash \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "hello world", "algorithm": "sha256"}'
Enter fullscreen mode Exit fullscreen mode

Response:

{
  "hash": "b94d27b9934d3e08a52e52d7da7dabfac484efe3...",
  "algorithm": "sha256",
  "input_length": 11,
  "hex": "b94d27b9934d3e08a52e52d7da7dabfac484efe3...",
  "base64": "uU0nuZNNPgilLlLX2n2r+sSE7+N6U4DukIj3rOLvzek="
}
Enter fullscreen mode Exit fullscreen mode

Both hex and base64 encodings are returned in every response. The algorithm defaults to sha256 if not provided.

Use cases for AI agents:

  • Generate unique IDs for documents (content-addressable storage)
  • Deduplicate content before storing in a vector database
  • Verify file integrity — hash the content, compare later
  • Generate deterministic cache keys for LLM responses
  • Create short fingerprints for long prompts

3. GitHub Integration — 4 Endpoints

For AI agents that work with code, four GitHub endpoints are available:

GET /github/repo — Repository details ($0.001)

Stars, forks, language, topics, last commit, description. Pass owner and repo as query params. Optional token for higher rate limits.

GET /github/search — Search repositories ($0.001)

Full GitHub Search syntax support. q=language:python stars:>1000, sort by stars/forks/updated, up to 30 results.

POST /github/issue — Create an issue ($0.002)

Programmatically create issues with title, body, and labels. Requires a GitHub PAT with repo scope.

POST /github/file/read — Read file content ($0.001)

Read any file from any public (or private with token) GitHub repository. Pass owner, repo, path, and optionally ref for a specific branch/commit.

Example — read a file:

curl -X POST https://api.iteratools.com/github/file/read \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "owner": "vercel",
    "repo": "next.js",
    "path": "package.json"
  }'
Enter fullscreen mode Exit fullscreen mode

Using via MCP

All 48 tools are available as an MCP server:

{
  "mcpServers": {
    "iteratools": {
      "command": "npx",
      "args": ["-y", "mcp-iteratools"],
      "env": {
        "ITERATOOLS_API_KEY": "YOUR_KEY"
      }
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

Add this to Claude Desktop, Cursor, or any MCP-compatible host and all tools appear automatically — including the new document converter, hash generator, and GitHub endpoints.

Pricing at a glance

Endpoint Price
POST /hash $0.001
GET /github/repo $0.001
GET /github/search $0.001
POST /github/file/read $0.001
POST /github/issue $0.002
POST /document/convert $0.003

No subscriptions, no monthly minimums. Pay only for what you use, via x402 micropayments on Base (USDC) or a standard API key.
