Every SnapTools tool is also an HTTP endpoint, running the same tools-core
engine as the web UI — so the API and the browser return identical results for identical
input. This page loads an interactive reference; the summary below is the same
information in static form.
Requests are authenticated with an API key issued from your dashboard and sent as a bearer token. Keys are shown once and stored hashed.
curl -X POST https://thesnaptools.com/api/v1/tools/json-minifier \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"json": "{ \"id\": 42 }"}'POST /api/v1/tools/{slug} — run one tool. {slug} is any slug listed below.GET /api/v1/tools/jobs/{runId} — poll an asynchronous run. Inputs over 500 KB are queued and return a queue_job_id to poll rather than a synchronous result.POST /api/v1/pipelines — run several tools in sequence, passing each step's output to the next.Every response uses the same envelope:
{
"success": true,
"data": { ... },
"meta": { "tool": "json-minifier", "processing_ms": 3, "timestamp": "..." }
}
Failures return success: false with an error object carrying a
code and message. Rate-limit state is returned on every response
in the X-RateLimit-* headers.
170 endpoints across
8 categories. Each takes POST /api/v1/tools/{slug}.
