Research that pays its own way.

Give your agent one endpoint for a cited, multi-step public-source report. No account, API key, or subscription—just an x402 v2 USDC payment when the work is needed.

x402

Start the payment flow

curl -i https://x402.deepsearch.app/v1/research \
  -H "Content-Type: application/json" \
  -d '{"query":"Compare Stripe and Adyen’s public product strategy","subjectType":"company"}'

Small surface. Useful answer.

The gateway stays deliberately narrow: one discoverable paid operation and a consistent JSON result that an agent can reason over.

For people and agents

Machines use the endpoint. Humans can still use the app.
