loophole tape — real-time labelled pump.fun intelligence, paid per request (x402, USDC on Solana)

Base URL: https://htrlhl3y49.execute-api.us-east-2.amazonaws.com Payment: x402 v2, scheme exact, network solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp, asset USDC. The facilitator pays the Solana network fee; a caller needs only USDC. No accounts, no API keys, no humans.

What it is

An independent Yellowstone gRPC capture of every pump.fun launch, curve trade and migration, turned into labels that are not sold anywhere else per request:

• creator reputation as knowable at launch time (look-ahead-safe: launches, curve-true graduations, rugs, median time to the dev's first sell) over 385k launches / 90k creators

• create-slot bundle, insider and dev shares (who bought in the launch slot and how much they hold)

• rug / close flags within seconds: creator_sold, bundle_dumped, curve_drained, pool_drained, curve_closed_low, migrate_below_grad

• graduation truth: a graduation is the curve witnessed at >= 84 SOL; everything else (mayhem closes, operator-seeded pools, ~31% of "migrations") is labelled a close

• insider-funded (warm) launches: the creator was funded by a watched insider wallet within 30 minutes of launching

• demand and holder microstructure: unique buyers, buy/sell flow, inflow stall, top-5 share, HHI

• a free market regime meter and free delayed samples of every paid route

Routes

Every response is {"ok": true, "t": <unix>, "data": {...}, "meta": {"feed_lag_s": ..., "last_slot": ..., "disclaimer": ...}}.

Pay from Python (reference client)

pip install "x402[httpx,svm]==2.22.0" "solana==0.36.7"
TAPE_PAYER_KEYPAIR=~/.config/solana/payer.json python pay_client.py https://htrlhl3y49.execute-api.us-east-2.amazonaws.com "/v1/launches/recent?limit=5"

Any x402 v2 client works the same way: call the route, read the PAYMENT-REQUIRED header, sign the USDC transfer, retry with PAYMENT-SIGNATURE; the PAYMENT-RESPONSE header carries the settlement signature. TypeScript: @x402/fetch + @x402/svm. Agents: the routes are listed in the PayAI x402 catalog and on agent402.tools; AgentKit's discover_x402_services finds them.

MCP (for agents that call tools)

The same intelligence is an MCP server over streamable HTTP at https://htrlhl3y49.execute-api.us-east-2.amazonaws.com/mcp, listed in the official MCP registry as io.github.gosadu/loophole-tape. Tools: market_regime and sample_mint (free), mint_risk_card ($0.025), recent_launches ($0.01), recent_rugs, recent_graduations, creator_reputation, wallet_profile ($0.02 each). Paid tools use x402 over MCP: the first call returns a payment-required result, the client pays in _meta["x402/payment"], the settlement comes back in _meta["x402/payment-response"]. Reference client: mcp_client.py (pip install "x402[httpx,svm]==2.22.0" "solana==0.36.7" "mcp<2").
