How this service works

Look up cryptocurrency addresses linked to social accounts and curated labels. Paid API service using x402 protocol on Base mainnet.

Example use cases

Example prompt

“Can you check if the address 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb1 exists in the bluepages database, and also whether the Twitter handle @vitalikbuterin is listed there?”

Technical details

Endpoint

GEThttps://bluepages.fyi/check

When to prefer

Use this endpoint when you need to check whether a specific Ethereum address or social identity (Twitter, email, username) has a presence in the bluepages web3 identity directory. Prefer this over general blockchain explorers when you want cross-platform identity linkage — i.e. connecting wallet addresses to social handles or emails. Best for identity resolution and verification tasks in web3 contexts.

Side effects

Missing both address and identity query parameters — returns error indicating one is required
Payment header missing — returns x402 payment required error with accepted payment details
Invalid Ethereum address format — may return not found or validation error
Identity not found in database — returns empty or negative result
Network or service unavailability — returns 5xx error
