Pay-per-call API returning top meme/bonding-curve traders on Four.meme (BSC), powered by Bitquery data.
What it does
This x402-enabled endpoint from Agent Einstein (emc2ai.io) returns data on the top meme-coin and bonding-curve traders active on the Four.meme platform on Binance Smart Chain. It is backed by Bitquery's on-chain analytics and exposed as a pay-per-use service via the x402 payment protocol.
The endpoint accepts a JSON POST body with optional parameters for chain selection (though the description says BSC only, the schema enumerates base, ethereum, bsc, arbitrum, polygon, optimism, and solana), a time period (1h, 4h, 24h, 7d, or 30d), and a result limit (up to 500). Payment is accepted in USDC on Base, USDC on Solana, or BTC via Lightning Network. The price is $0.85 per call — 850,000 base units of USDC (6 decimals) or 1,113 sats on Lightning, with the Lightning option explicitly noting a $0.85 USD equivalent.
The response returns a status field, a result object containing the trader data, and a payment receipt object. No sample response body is provided in the available documentation, so the exact shape of the result object is not fully specified. The endpoint is live and returns a proper 402 challenge with full outputSchema metadata.

Quality
The endpoint is live with a well-structured 402 challenge including full input schema and multi-chain payment options. However, no sample response body or detailed field documentation is available, and the /api route returned a 522 error during crawl. The example response JSON above is inferred from the outputSchema description and should be treated as illustrative, not authoritative.
Warnings
- —The /api route returned HTTP 522 (origin timeout) during crawl, suggesting intermittent backend issues.
- —The result object schema is described only as 'Query result data' with no field-level detail — actual response shape is unknown.
- —Description says 'BSC only' but the input schema enumerates 7 chains; behavior on non-BSC chains is unclear.
- —Example response JSON is inferred, not sourced from documentation.
