Live rug checks for new pump.fun memecoins on Solana (calibrated rug probability and graduation odds, holders, creator record, rug flags) and Robinhood Chain pons launch and token risk cards, computed in real time from our own independent capture of every on-chain event (not resold third-party data). Pay per request in USDC on Solana or Base through x402 with no account: $0.001-$0.04 per data call, $5.00 per daily dataset file; prepaid keys ($0.10 trial, $2.00) serve clients without an x402 library. Responses report coverage, freshness and observed evidence. Priced skills are paid per call with x402 (USDC on Solana mainnet or Base) over HTTP or MCP; the A2A endpoint answers any message with the catalog, the payment terms and the exact HTTP/MCP call for the skill you name. How our rug calls compare, scored against settled outcomes (2100 pump.fun mints, 7 of the last 7 UTC days on record (2026-10-01 to 2026-10-07)): our radar at rug odds of at least 50%, called a median 12.6 s after launch, precision 73.1% (583 of 798, 95% interval 69.9 to 76.0%), recall 74.0% (583 of 788, 95% interval 70.8 to 76.9%) on rugs within 300 s; RugCheck's free public report (any danger risk), read a median 12.8 h after launch, precision 33.3% (50 of 150, 95% interval 26.3 to 41.2%), recall 5.6% (50 of 889, 95% interval 4.3 to 7.3%). The outcome labels are ours and the sample is what our radar listed; method, caveats and every row: https://api.loopholetape.com/compare (https://api.loopholetape.com/v1/compare, https://api.loopholetape.com/v1/compare/rows).
mint_risk_card — Solana token safety card: holders, creator and rug flags for a pump.fun memecoin; authorities and Token-2022 extensions for any SPL mint ($0.025).

— Solana wallet profile: class and realised PnL from our pump.fun leaderboard, plus holdings. Use to classify a wallet buying a pump.fun memecoin (insider, latency_bot or skilled) and read its realised PnL when it ranks on our leaderboard; it describes the wallet, not a mint's rug risk (use GET /v1/check/mint).

rhc_curve_trades — Robinhood Chain pons memecoin curve: reserves and price after every trade. Use when you index or price a pons curve and need the reserves after each trade, which the deployed curves do not emit; check your own numbers first on the free sample GET /v1/rhc/sample/trades?address=.

Each new payment here buys a new $2.00 key.
