Monitor smart contract deployments on Base and other chains via x402 micropayment.
What it does
This x402-enabled endpoint from Erudite Intelligence LLC lets callers monitor contract deployments on blockchain networks. You POST a JSON body containing a contract address and a chain identifier (e.g. "base"), and the endpoint returns deployment data. Payment is required per-call via the x402 protocol, settling in USDC on Base (EIP-155:8453) or USDT on Tron, at $0.01 per request.
The endpoint is live and returns a proper x402 v2 challenge with two accepted payment options: USDC on Base via the Coinbase CDP facilitator, or Tether USD on Tron. The price is 10,000 base units in both cases — which equals $0.01 given 6-decimal stablecoins. The provider, EruditePay, operates a multi-chain x402 payment bridge supporting 20 blockchains and is registered as a FinCEN MSB.
Documentation is sparse for this specific monitoring endpoint. The Bazaar schema embedded in the x402 challenge describes the input (address + chain fields) and a generic output shape ({success: true, data: {}}), but no detailed field-level documentation for the response data object is available. The provider's landing page focuses on the facilitator bridge itself rather than individual data endpoints. Callers should expect JSON output but should test with real payments to discover the full response structure.
Capabilities
Use cases
- —Detect new smart contract deployments on Base or other supported chains in near-real-time
- —Monitor a specific deployer address for new contract creations
- —Feed contract deployment events into an analytics or alerting pipeline
- —Automate discovery of newly deployed contracts for security auditing
Fit
Best for
- —Agents or bots that need programmatic, pay-per-call access to contract deployment data
- —Developers building blockchain monitoring dashboards
- —Security researchers tracking deployer addresses
Not for
- —Free or high-volume bulk historical data retrieval (each call costs $0.01)
- —Monitoring non-EVM chains not listed in the supported set
- —Users who need detailed ABI or source-code analysis of deployed contracts

Quality
The endpoint is live (402 challenge captured) with a clear schema for input and pricing, but the response data structure is essentially a stub ({data: {}}), there is no dedicated documentation page, and the provider's docs URL returns a 404. The actual content of the 'data' field is unknown.
Warnings
- —Response schema is a stub — the example output shows an empty 'data' object with no documented fields
- —Provider documentation at /docs returns endpoint_not_found; no external docs site was reachable
- —The exact content and granularity of contract deployment data returned is unverified
