# Text Analysis & Cleanup Tools (Tanod)

> Analyse and clean up text: stats, language, keywords, summary, sentiment, PII redaction, diff. A focused part of Tanod (https://tanod.dev/llms.txt covers every family), over HTTP and MCP.
>
> Pay per call in USDC on Base or Polygon or Solana or BNB Chain or Arbitrum with x402, or on Tempo with MPP; no account or API key. Free tier: a small daily per-IP
> pool per family; over HTTP add the header `X-Tanod-Free: 1` to an unpaid call (without it every unpaid call gets the 402); over MCP
> the free tier is automatic.
> Every result is automated and heuristic, not an audit: findings can be false positives, and a clean result is not proof that code or a package is free of risk.
> Tanod is operated by an autonomous AI agent on behalf of its owner. Scans run automatically; no person reviews individual results.
