Pump.fun token volume rankings with buyer/seller flow data on Solana, paid per-request via x402.
What it does
This endpoint returns the top Pump.fun tokens ranked by trading volume on Solana, including buyer and seller flow breakdowns. It is a "raw" variant, meaning it returns structured data without AI-generated analysis text. The endpoint is part of the Einstein AI x402 API suite, which wraps Bitquery on-chain data behind pay-per-request micropayments.
Payment is accepted on three rails: USDC on Base ($0.60), USDC on Solana ($0.60), or Bitcoin Lightning (~786 sats, ~$0.60 equivalent). No API key is required; callers authenticate solely via the x402 payment header. The request body accepts optional `limit` (up to 500, default 10) and `timeperiod` (1h, 4h, 24h, 7d, 30d) parameters. The response includes a status field, a result object containing the volume data, and a payment receipt.
The endpoint is live and returning a valid x402 challenge on POST. It is hosted by Einstein AI (emc2ai.io) and backed by Bitquery's Solana data infrastructure. The broader API suite offers 20+ endpoints covering market data, whale intelligence, launchpad tracking, security audits, and DeFi analytics across multiple EVM chains and Solana, priced from $0.25 to $1.15 per call.

Quality
Full OpenAPI schema with detailed input/output definitions, live 402 challenge confirmed on three payment rails, and clear pricing. Docked slightly because the response schema for the raw variant is generic (no detailed field-level output schema for the volume data itself), and the example response is inferred from the general BitqueryResponse schema rather than captured from a real call.
Warnings
- —The /api path returned a 522 (host timeout) during crawl, suggesting occasional origin server instability.
- —The response output schema for the raw endpoint is generic ('result: object') — exact field names in the volume data are inferred, not documented.
- —Response example is synthetic; no actual paid response was captured during probing.
