Small tools that clean up messy data. Fast, and free to try.

Repair broken JSON, hash text, chunk Markdown, convert YAML or XML, and more. People and AI agents can call these tools over HTTPS. Heavy jobs (PDFs, Word files, crawling) are not on this API — those live on our paid Apify actors.

Free: 50 calls per IP each UTC day Free key: 200 calls per key each UTC day 16 KB max per call No paid billing yet

Start in one minute

You do not need a key to try it. Send JSON to any tool:

curl -sS https://tidybytetools.tidybytetools.workers.dev/v1/hash -H "Content-Type: application/json" -d '{"text":"hello"}'

Want a higher free cap, or a key for marketplaces? Create one instantly. We show the key once:

curl -sS -X POST https://tidybytetools.tidybytetools.workers.dev/keys -H "Content-Type: application/json" -d '{"label":"my agent"}'

Then send it as Authorization: Bearer tbt_..., or X-Api-Key, or an api_key query parameter. Never put a key in the URL path.

Tools on this API

19 pure-compute endpoints. They run at the edge. They do not fetch other websites or open files like PDFs.
