About

Every route publishes its own inputs — type, required flag and a worked example per field — which is why this listing carries real schemas rather than a description and a price. Apiosk resells it: the treasury settles the provider's own x402 in USDC on Base and the buyer pays the list price plus the Apiosk fee.

GET /alpha/launches LAUNCH RADAR — one call discovers what just launched AND rug-screens every candidate through the composite score (static + live buy/sell simulation, or the Solana dual-engine) + liquidity, returning a ranked shortlist with a per-token verdict. Replaces 10+ free-API calls and the coordination logic an agent would build: aggregating launch feeds, running per-candidate honeypot simulations, computing the composite risk score, reconciling free sources, and ranking by safety. The proactive 'give me safe alpha' endpoint for launch-sniping agents.

GET/wx/storm
$0.01 default
Description

STORM RISK for any coordinate on Earth — resolves NOAA/NWS active-alert GeoJSON polygons with real point-in-polygon geometry, blends in wind speed and alert severity, and returns ONE scored risk verdict. Replaces the whole pipeline an agent would otherwise build: fetch the alert feed, parse multi-ring GeoJSON, run point-in-polygon per alert, reconcile severity vocabularies, and merge a second wind source. Independently scored 9/10 by a bot-buyer panel: 'paying $0.04 to instantly bypass complex GeoJSON parsing, point-in-polygon math, and multiple API orchestration is a highly efficient time-sav

GET/yield/surface

Risk-adjusted yield surface across Base and Ethereum lending, DEX, and restaking pools -- pulls real pool data from yields.llama.fi, computes IL-risk-adjusted APY and cross-protocol TVL context, sorted by adjusted return. Replaces 3+ API fetches plus APY math, TVL normalization, and risk weighting an agent would do locally.
