Built for the
Autonomous Economy.
No SDK, no account, no API key to get started. Every endpoint is plain HTTP — call it directly with curl, fetch, or any HTTP client. Free tiers exist on most endpoints; paid calls settle instantly over x402. Full pricing at /pricing.

REAL ENDPOINT
curl -X POST https://stillosdigitalholdings.com/notary/screen-entity \
-H "Content-Type: application/json" \
-d '{"agent":"your-id","entity":"Acme Corp"}'
# Free tier: 5 calls/agent/day. No account, no API key.
# Past the free tier, the same call returns HTTP 402 with a real
# x402 payment request (payTo, USDC asset, price) -- pay and retry
# the exact same request for a signed, verifiable receipt.
