Two calls to first result
Start here
curl -s -X POST https://getattest.com.au/api/v1/keys -H "content-type: application/json" -d '{"label":"my agent"}'
# then, with the key it returns:
curl -s -X POST https://getattest.com.au/api/v1/text/stats \
-H "authorization: Bearer $ATTEST_API_KEY" \
-H "content-type: application/json" \
-d '{"text":"Hello there."}'
POST /api/v1/keys issues a key with 25 free credits and no signup. Send the key as a bearer token in the authorization header. One key and one credit balance cover every service, including Attest Capture. A failed call is refunded automatically. Costs below are credits per successful call; a free tool costs nothing but still needs a key and still writes a receipt.
