What it does

This endpoint provides a token-centric view of whale accumulation patterns, including net capital flows and top holder data across multiple blockchains. It is part of the Einstein AI x402 API suite, which wraps Bitquery on-chain data behind x402 micropayments. The endpoint returns raw structured data (no AI analysis layer) for whale intelligence use cases.

The endpoint accepts POST requests with optional parameters for chain (base, ethereum, bsc, arbitrum, polygon, optimism, solana), result limit (up to 500), and time period (1h to 30d). It costs $0.85 per request, payable in USDC on Base (EIP-155:8453), USDC on Solana, or BTC via Lightning Network. No API keys are required — payment is handled entirely through the x402 protocol's X-PAYMENT header with a signed transfer authorization.

Supported chains span major EVM networks and Solana. The response includes a status field, result data object with whale accumulation metrics, and a payment receipt. The 90-second timeout on Base and 60-second timeout on Solana suggest the endpoint performs non-trivial on-chain data aggregation behind the scenes. The broader Einstein AI platform also offers related endpoints for smart money tracking, wallet holdings, holder concentration, and other whale intelligence tools at varying price points from $0.25 to $1.15.

Use cases

  • —Monitoring large wallet accumulation patterns for a specific token or chain
  • —Identifying net capital inflows/outflows driven by whale activity
  • —Building trading signals based on whale behavior across EVM chains and Solana
  • —Feeding whale intelligence data into autonomous trading agents
  • —Screening tokens for concentrated holder risk before investment

Fit

Best for

  • —AI agents needing programmatic whale intelligence without API key management
  • —Multi-chain whale tracking across Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, and Solana
  • —Pay-per-use on-chain analytics with no subscription commitment
  • —Raw data consumers who want structured JSON without AI interpretation

Not for

  • —Users needing free or subscription-based unlimited access to whale data
  • —Real-time streaming or websocket-based whale alerts
  • —Historical data beyond 30-day lookback windows

Quality

0.78/ 1.00

The endpoint is live with a well-formed x402 402 challenge, full OpenAPI spec with schemas, multi-network payment options, and clear pricing ($0.85). Docked slightly because the specific response data shape for whale-intel/raw is not fully documented in the OpenAPI (it's not listed as a separate path — only /whaleintel is), and no real example response with actual whale data fields is available. The /raw variant's exact output fields must be inferred.

Warnings

  • —The /x402/bitquery/whale-intel/raw path is not explicitly listed in the OpenAPI spec — only /x402/bitquery/whaleintel (at $1.00) is documented. This endpoint may be an undocumented raw-data variant.
  • —The /api route returned a 522 (host error) during crawl, suggesting some backend instability.
  • —Actual response data fields (e.g., specific whale metrics, holder lists) are not documented — the output schema only describes generic status/result/payment fields.
