Independent, daily-updated trust & safety data for the x402 agent-payment economy (HTTP 402 + stablecoins on Base) and the MCP server ecosystem — by PulseFeed. AI agents increasingly pay for APIs autonomously over x402 and connect to MCP servers that can run code on install. But 20% of listed x402 endpoints are dead or invalid, and "live" is not the same claim as "payable": of 24131 endpoints that return a valid 402, only 22426 across 1904 operators are things an agent can actually buy — the rest are documentation placeholders, testnet sandboxes priced in dollars, or payment schemes outside the x402 spec. Both figures are in ecosystem.json as healthyEndpoints and payableEndpoints; compare…

Part of a dataset collection on Hugging Face. Daily health snapshots of the AST SpaceMobile BlueBird direct-to-cell satellite constellation, derived from CelesTrak GP (General Perturbations) data. Tracks the BlueWalker 3 prototype and all production BlueBird satellites as the constellation is built out. AST SpaceMobile is developing a unique LEO constellation designed to provide broadband connectivity directly to ordinary unmodified smartphones, without special satellite-phone hardware. The BlueBird satellites use unusually large phased-array antennas (up to 700 m2) to close the link budget with handset-sized antennas on the ground. The BlueWalker 3 prototype launched in 2022, the first…

One row per player, game, team, and statistic group. Regular-season games at AA, High-A, and Single-A, subject to configured coverage. Source: MLB Stats API. Data is extracted from box-score stats, never seasonStats. Missing statistics are null. pitchingIPstr uses baseball notation; use pitchingouts for arithmetic. Files are grouped by season, historical league ID, and team ID. catalog.json maps IDs to names and table paths. The train split is a loading convention; no training/test split has been applied. state/index.json records season completion; partially backfilled seasons can be visible. state/SEASON.json records the games successfully stored. Current-season games are refreshed…

MLEBench Goal and Flame Chase 6h Campaign Backup Private operational backup of the 2026-09-03 FlowBench-isolated MLEBench campaigns. It preserves the historical Goal and Flame Chase evidence and the fresh 75-task Kimi K3 run, 75 GLM-5.3 Goal cells, and 75 fixed-time GPT-5.6 Sol/Kimi K3 Flame Chase cells. Historical Kimi records do not count toward the fresh continuation result. At this snapshot, the
