DocketLayer is a pay-per-query API that gives AI agents programmatic access to federal court docket monitoring. Your agent submits a case ID and court code, pays $0.99 in USDC via the x402 protocol, and receives structured JSON with change detection built in. No accounts. No subscriptions. No API keys. The payment is the authentication.

​
How it works

1

Submit

Your agent makes a GET request to /v1/case with a case ID, court code, and a last_checked timestamp.
2

Pay

DocketLayer responds with HTTP 402. Your x402 client pays $0.99 in USDC on Solana automatically and retries the request.
3

Receive

DocketLayer returns structured JSON — changed: true or false, and if true, the full details of every new filing since your last check.

​
What you need

  • A Solana wallet funded with USDC
