Research Organizations API
Every research organization in the world as an API — powered by ROR, the Research Organization Registry. ROR assigns a persistent open identifier (a ROR ID) to universities, government labs, companies, nonprofits, hospitals, archives and research facilities, with rich, curated metadata and crosswalks to GRID, ISNI, Wikidata and the Crossref Funder Registry. Search the registry by name (and filter by country or organization type); resolve any ROR ID to its full record — names, acronyms and aliases, types, location (city, country, coordinates), website, domains, external identifiers and relationships to parent and child organizations; and match a messy free-text affiliation string ("Dept. of Physics, Heidelberg University, Germany") to the most likely organizations with a confidence score — perfect for cleaning and disambiguating author-affiliation data. It is a research-organization identifier registry, distinct from a plain university directory, and a natural companion to ORCID (for people) in any scholarly-metadata stack. Open data from ROR (CC0).

DAO Treasury API
Live treasury composition for DeFi protocols and DAOs, keyless. For any protocol it returns the value its DAO holds in its treasury, split into the protocol OWN governance token versus real diversified reserves (stablecoins, ETH, BTC and other assets) — the single most-watched measure of treasury health and runway — broken down per chain, plus the treasury value over time. Live, nothing stored. The DAO-treasury layer for DeFi research, governance, risk and dashboard apps — this is treasury composition (own-token vs real reserves), not protocol TVL.

Stock Analyst Ratings & Price Targets API
Live Wall Street analyst coverage for US stocks from Nasdaq — no key, nothing stored. The "what do the analysts think" view of a stock: the consensus recommendation, the price target and how both have moved over time, distinct from the quote, movers, earnings and insider APIs in the catalogue. The consensus endpoint returns the recommendation picture — the number of analysts rating the stock buy, hold and sell, the total coverage and the mean rating (from Strong Buy to Strong Sell). The target endpoint returns the analyst price target — the low, mean and high targets, the current price and the implied upside to the mean target. The history endpoint returns the consensus timeline — the price target and the buy / hold / sell split month by month — so you can see whether sentiment is improving or deteriorating. Build research dashboards, price-target trackers, upgrade/downgrade alerts and valuation tools on top of real Nasdaq analyst data. Look up any US stock by its ticker symbol; targets and counts are returned as clean numbers and the implied upside is computed against the live price.

Crypto Coin Profile API
Live project profile, developer activity and official links for any cryptocurrency — what a coin is, not what it costs — served from the public CoinGecko feed with no key and nothing cached. The profile endpoint returns the project's description, market-cap rank, categories (Layer 1, DeFi, Meme and more), genesis date, hashing algorithm, country of origin, the community sentiment split, and the all-time high and low with their dates — Ethereum is a rank-2 Smart Contract Platform that launched in 2015 with an all-time high near $4,946. The developer endpoint returns the GitHub development activity investors use to gauge a project's health: stars, forks and watchers, the count of total and closed issues, merged pull requests and recent commits — Bitcoin's repositories carry over seventy thousand stars and thousands of merged pull requests. The links endpoint returns every official link: homepage, whitepaper, block explorers, GitHub repositories, the subreddit, Twitter handle, Telegram and forums. This is the project-research and due-diligence layer for any crypto research, screener, wallet or portfolio app. Live from CoinGecko, nothing stored. Distinct from price, market-cap and OHLC APIs — this is the project profile, developer activity and links. 4 endpoints.

Crypto Tokenomics API
Live crypto tokenomics — supply and dilution metrics for any cryptocurrency, powered by CoinGecko. For any coin it returns the circulating, total and maximum supply, the percentage of the maximum supply already issued, the market cap and the fully-diluted valuation (FDV), and the market-cap-to-FDV ratio — the share of supply already unlocked — together with the dilution overhang, the percentage of FDV still locked or yet to be minted. It can also rank the top coins by dilution overhang (which assets have the most future supply hanging over them) or by how much of their cap is issued. The supply-and-dilution layer that token research, due diligence and risk dashboards need. Live, no key, no cache. Distinct from price, market-cap and all-time-high APIs — this is the tokenomics analytic.
