What it does

This endpoint returns a leaderboard of alpha-generating wallets, including buy/sell flow data and accumulation metrics. It is part of the Einstein AI x402 API suite, which wraps Bitquery on-chain data behind x402 micropayment gates. The endpoint accepts POST requests with optional parameters for chain (base, ethereum, bsc, arbitrum, polygon, optimism, solana), limit (up to 500 results), and timeperiod (1h to 30d). The "/raw" suffix indicates this endpoint returns raw data without AI-generated analysis layered on top.

Payment is $0.85 per request in USDC on Base (maxAmountRequired: 850000, 6 decimals), USDC on Solana, or 1113 sats via Lightning Network. No API key is required — authentication is handled entirely through the x402 payment header. The endpoint returned a valid 402 challenge during probing, confirming it is live and accepting payments. Supported payment addresses differ per network: an EVM address on Base, a Solana pubkey, and a Lightning merchant ID.

The broader Einstein AI platform offers 20+ x402 endpoints covering market data, whale intelligence, launchpad monitoring (Pump.fun, Zora), security audits (rug pull scanning, MEV detection), DeFi arbitrage scanning, and an autonomous AI agent endpoint. Prices across the suite range from $0.25 to $1.15 per call. The platform also supports CDP Bazaar discovery for agent-to-agent commerce. Note that this specific alphaleaders/raw endpoint is not explicitly listed in the published OpenAPI spec paths, though the x402 challenge confirms it exists and is operational.

Quality

0.72/ 1.00

The endpoint is live with a valid 402 challenge, full outputSchema in the challenge, and a comprehensive OpenAPI spec for the broader API suite. However, this specific /alphaleaders/raw path is not in the published OpenAPI paths, and the response schema for the leaderboard data is inferred from the generic BitqueryResponse schema rather than documented explicitly.

Warnings

  • —The /x402/bitquery/alphaleaders/raw endpoint is not listed in the published OpenAPI spec paths — it was discovered only via the 402 challenge probe.
  • —The /api route returned a 522 (host error) during crawl, suggesting intermittent backend availability.
  • —Response data schema for the leaderboard is inferred; actual field names may differ from the example.
