Look up labels/tags for wallet or contract addresses on Base via x402 micropayment.
What it does
This endpoint from Erudite Intelligence LLC provides crypto address labeling ("Crypto data intelligence") on the Base network. You POST a wallet or contract address and receive label/tag data associated with that address. The endpoint is gated behind the x402 payment protocol (v2), returning a 402 challenge until payment is provided.
Payment is accepted in two ways: USDC on Base (eip155:8453) at 0.01 USDC per call, or USDT on Tron (tron:728126428) at 0.01 USDT per call. The x402 facilitator is Coinbase CDP for the Base option. The provider is Erudite Intelligence LLC, a FinCEN MSB-registered entity. The Bridge facilitator at bridge.eruditepay.com supports 20 blockchains and handles verify/settle steps.
Documentation is sparse — the endpoint description is simply "Crypto data intelligence" and the example output is a generic `{"success": true, "data": {}}` stub. There is no detailed schema for what fields appear inside `data`, no enumeration of supported label types, and the docs link (docs.eruditepay.com) was not reachable in the crawl. The input schema requires a JSON body with an `address` string field described as "Wallet or contract address." The endpoint path includes `/base/` suggesting it is scoped to the Base L2 chain, though this is inferred from the URL structure rather than explicit documentation.
Capabilities
Use cases
- —Identify known entities (exchanges, protocols, scammers) behind a Base address before transacting
- —Enrich on-chain transaction data with human-readable labels for compliance dashboards
- —Agent-driven wallet screening: automatically label counterparty addresses during trade execution
- —Build address books that auto-tag new addresses encountered in DeFi interactions
- —Power AML/KYC workflows by resolving addresses to known entity labels
Fit
Best for
- —AI agents that need per-call address intelligence without API key management
- —Compliance and risk teams screening Base wallet addresses
- —On-chain analytics pipelines that need entity resolution for addresses
Not for
- —Bulk labeling of millions of addresses (per-call micropayment model would be expensive at scale)
- —Chains other than Base (this specific endpoint is scoped to /base/)
- —Detailed transaction history or balance queries — this is label/tag data only

Quality
The endpoint is live (402 challenge captured) with a clear input schema and pricing, but the output schema is a stub with no detail on what label data is actually returned. No external documentation was reachable. The description 'Crypto data intelligence' is vague.
Warnings
- —Output schema is a generic stub — no documentation on what fields appear inside 'data'
- —docs.eruditepay.com was not crawled/reachable; /docs on bridge returns 404
- —Endpoint description is vague ('Crypto data intelligence') — actual label taxonomy unknown
- —Scope appears limited to Base chain based on URL path; no confirmation of multi-chain label coverage at this endpoint
