Clerk

The AI-native legal data layer for the agentic economy.

Clerk provides permissionless access to 500M+ US federal court records across 94 federal courts through 11 data endpoints. Built on Base, it eliminates subscriptions and API keys by using x402 micropayments at just $0.001 per query in USDC. Stack legal intelligence into any AI agent workflow.

What is Clerk?

Clerk is an x402-paid API that exposes US federal court records to AI agents. No API keys to manage. No subscriptions. No forms. Agents call the endpoint, the 402 response triggers a USDC payment, the call retries automatically, and the agent receives JSON.

The agent calls. The 402 fires. The agent pays. The data returns. No keys, no forms, no humans in the loop.

Install

pip install clerk-api

Requires Python 3.10+. One dependency: httpx (or requests as a fallback).

Quick start

/search works in demo mode without payment — perfect for trying the SDK first:

from clerk_api import ClerkClient

client = ClerkClient()  # no auth — demo mode

cases = client.search("SEC v Ripple")
for case in cases:
    print(f"{case['case_name']} — {case['court']} — {case['date_filed']}")

For full access on paid endpoints, you send USDC externally first (any wallet on Base — MetaMask, Bankr, web3.py, etc.) to Clerk's payment wallet, then pass the resulting transaction hash to the client:

import os
from clerk_api import ClerkClient

# 1. Send $0.001 USDC to the Clerk payment wallet on Base (you do this
#    out-of-band using any web3 client). Capture the resulting tx hash.
# 2. Pass the tx_hash to the SDK. The client encodes it as an x402
#    payment header that the server validates against the on-chain tx.
client = ClerkClient(tx_hash=os.environ["CLERK_PAYMENT_TX"])

docket = client.docket("67614382")
print(docket)

Free unlimited access: wallets holding 1B+ $CLERK on Base bypass per-call payment entirely. The protocol auto-detects $CLERK balance from the payment context.

$CLERK token

Pay-per-query via x402 micropayments. Or hold 1B+ $CLERK on Base to unlock unlimited free queries on every endpoint.

The protocol auto-detects $CLERK balance from your signing wallet on each request.

Delegated signer pattern (production)

For agent ops at scale, never put your main $CLERK-holding wallet in a script. Instead, delegate signing to a fresh wallet funded only with gas.

python examples/register_delegates.py --csv my_agents.csv

Your main wallet stays cold; agent wallets do all the signing. See examples/register_delegates.py.

Demo mode

/search works without payment in demo mode (limited results per IP per hour). Use it to test the integration before wiring up x402.

client = ClerkClient()  # no key — demo mode
results = client.search("Binance", limit=5)

Limits

• Federal courts only (94 district courts + appellate). State courts not covered.
• Sealed dockets are not exposed.
• Surfaces public records only. Not legal advice — interpretation requires a licensed attorney.
