Validate AI claims against live data: check endpoints, count competitors, and test hypotheses. Includes free and paid tools via x402.

Read-only relational-readiness preflight for AI agents evaluating market trust, permission, evidence gaps, pilot readiness, and scale readiness in African and other high-context markets.

Gateway connector between LLM agents and world data, providing access to financial market prices, macroeconomic indicators, and news through a bundled endpoint catalog.

Enables coding agents to query AI model API prices, including historical point-in-time lookups with cited sources, using a bundled dated dataset and requiring no API keys.

An MCP server exposing a registry of paper-backed quantitative trading methods plus a deterministic, no-LLM decision helper for reproducible trading research.

A read-only MCP server for bounded table discovery, deterministic profiling, and maintained-library statistical testing (Welch's t-test and two-proportion z-test) using SQLite, pandas, SciPy, and statsmodels.

Enables MCP clients to search Yellow Pages local businesses by keyword and location and retrieve full listing details such as phone, hours, services, brands, and payment methods.

Generates synthetic time-series test data with configurable trend, seasonality, noise, anomalies, and multiple correlated streams, outputting JSON, CSV, or SQL.

Recommends study designs for a research question, states the identifying assumptions to verify, and returns runnable R, Python, or Julia code with a formatted citation for every source, drawn from methodological textbooks, an R package, and research articles on causal inference, econometrics, statistics, and machine learning.

Provides AI agents with Korean national fiscal data (budgets, settlements, and fiscal programs) from multiple government APIs through 7 tools, enabling natural language queries.

Provides access to 9 AI executives offering board-ready business intelligence, competitor analysis, trend monitoring, and more via agent-payable endpoints.

Enables listing, reading, and searching daily AI news from AI Daily Insights with structured tools and no API key required.

MCP server exposing ATLAS research capabilities: live tokenized stock market data, on-chain source-of-truth reads, and published research atlases. Connects to MCP clients over stdio with no API keys required for public testnet endpoints.

MCP server that lets AI assistants like Claude Code and Codex drive the co-scientist engine to generate, review, rank, and evolve scientific hypotheses via an Elo tournament.

Enables LLM clients to retrieve official Turkish central-bank exchange rates, MPC (PPK) decisions, Inflation Reports, Financial Stability Reports, and market-participant surveys, with page- or bulletin-level citations and sentence-level comparisons of policy statements. It works without any API key for FX data and documents, while an optional free EVDS key unlocks the full statistical catalogue for policy rates, inflation, and reserves.

Enables agents to search, inspect, preview, download, and cite LTER and EDI ecological data packages from the PASTA+ repository, including metadata, entities, citations, change feeds, and provenance. An API key unlocks quality reports, lineage, read counts, and other privileged PASTA endpoints.

Enables agents to query live artificialanalysis.ai data — leaderboards, model digests, benchmarks, pricing, cost-per-task, speed, provider endpoints, and image/video/speech/music arenas — through token-efficient table tools that need no API key. It works from the site's public RSC payloads by default, with an optional JSON-API backend (and automatic fallback) for capability and coding/agentic indexes.
