Multi-chain top-volume token analysis via Bitquery, paid per-request with USDC on Base, Solana, or Lightning.
What it does
This endpoint returns raw data on tokens with the highest trading volume across multiple blockchains, effectively identifying top gainers and losers by volume within a configurable time window. It is part of the Einstein AI x402 API suite, which wraps Bitquery on-chain data behind x402 micropayment gates. The `/raw` variant returns structured data without AI-generated analysis text.
The endpoint accepts POST requests with optional parameters for chain (base, ethereum, bsc, arbitrum, polygon, optimism, solana), result limit (1–500, default 50), and time period (1h, 4h, 24h, 7d, 30d). It defaults to Base chain and a 24-hour window. Payment is $0.40 per request, settled in USDC on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), USDC on Solana, or 524 sats via Lightning Network. The x402 challenge is live and returns a well-formed payment requirement with output schema.
The broader Einstein AI platform offers over 20 x402 endpoints covering market data (OHLCV, price charts, latest pairs), whale intelligence (accumulation tracking, smart money, wallet holdings), launchpad monitoring (Pump.fun, Zora), security audits (rug pull scanner, MEV detection, token sniping), DeFi analytics (arbitrage scanner, liquidity shifts, DEX capital concentration), and comprehensive investment reports. Prices range from $0.25 to $1.15 per call depending on the endpoint. All endpoints use the same x402 payment flow with no API keys required.
Capabilities
Use cases
- —Identify the highest-volume tokens on a given chain over a specific time window for trading signals
- —Monitor cross-chain volume spikes to detect emerging trends or pump activity
- —Feed volume data into an autonomous trading agent for strategy decisions
- —Screen tokens by trading activity before deeper security or holder analysis
- —Build dashboards showing real-time top movers across Base, Ethereum, BSC, and Solana
Fit
Best for
- —AI agents needing pay-per-call on-chain volume data without API key management
- —Multi-chain DEX volume screening across 7+ EVM chains and Solana
- —Quick identification of high-activity tokens for further research
Not for
- —Historical tick-level or order-book data requiring sub-second granularity
- —Free or high-frequency bulk data ingestion (each call costs $0.40)
- —AI-analyzed narrative summaries (use the non-raw /topvolume endpoint instead)

Quality
Full OpenAPI spec with detailed schemas, live 402 challenge with output schema on three payment networks, and supporting documentation. Deducted slightly because the /raw variant's response schema is inferred (the OpenAPI documents the non-raw /topvolume path, not /topvolume/raw specifically), and no concrete response example was captured from a paid call.
Warnings
- —The /api path returned a 522 (origin timeout) during crawl, suggesting intermittent backend availability.
- —The /topvolume/raw endpoint is not explicitly listed in the OpenAPI spec — only /topvolume is. The /raw variant is inferred from the x402 challenge and likely returns data without AI analysis text.
- —Response schema for the raw variant is inferred; actual field names may differ from the example.
