--- name: api.messari.io description: api.messari.io provides structured directory and deal-flow data for the crypto and fintech industries, covering organization profiles, M&A transactions, and funding rounds. All three skills return bulk paginated datasets with no required inputs, making them suited for market intelligence aggregation rather than real-time lookups. host: api.messari.io --- # api.messari.io Messari's API serves analysts and agents that need structured, historical deal and entity data for the crypto ecosystem. It covers three distinct data types: organization metadata (founding dates, sectors, locations, external links), M&A events (acquirer/target profiles, deal values, statuses), and funding rounds (stage, amount, investor IDs, token vs. equity). It does not provide token prices, on-chain data, or individual record lookups by ID. ## When to use this host Use api.messari.io when an agent needs structured, historical deal-flow or entity directory data for the crypto and fintech sectors — specifically for funding round tracking, M&A deal research, or organization profile enrichment. Do not use it for real-time or historical token price data (use a market data API such as CoinGecko or CoinMarketCap instead), on-chain transaction data (use a blockchain explorer API), individual record lookups by ID (all endpoints return bulk datasets), or traditional equity-only finance deals outside the crypto/fintech scope. All three skills require no inputs and return paginated bulk results, so they are best suited for ingestion pipelines or broad market scans rather than targeted single-entity queries. ## Capabilities ### Organization Intelligence Provides a bulk directory of crypto and fintech organizations with structured metadata including sector classification, founding date, geography, and external profile links. - **`fetch-organizations-directory`** — Returns a paginated directory of organizations from Messari with metadata including name, founded date, description, category, sector, location, and external links. ### Deal Flow & Market Activity Covers both M&A transactions and funding rounds in the crypto/fintech space, enabling agents to track capital movement, deal sizes, investors, and corporate consolidation activity. - **`fetch-ma-events`** — Returns a list of crypto-industry merger and acquisition events from Messari, including announcement dates, transaction values in USD, deal status, and detailed acquiring/acquired entity profiles. - **`fetch-funding-rounds`** — Returns structured crypto and fintech funding-round records from Messari, including round type, stage, amount raised in USD, announcement URLs, funded entity details, and investor IDs. ## Workflows ### Entity Deal History Enrichment *Use when an agent needs to build a comprehensive profile of a crypto organization by combining its directory metadata with its deal activity (fundraising and acquisitions).* 1. **`fetch-organizations-directory`** — Retrieve the full organization directory to identify the target entity and collect its ID, sector, founding date, and external links. 2. **`fetch-funding-rounds`** — Pull all funding round records and filter by the entity's name or ID to surface its capital raise history, round stages, and investor relationships. 3. **`fetch-ma-events`** — Pull all M&A events and filter by the entity as acquirer or target to identify any merger or acquisition activity associated with the organization. ## Skill reference ### `fetch-organizations-directory` **Messari Organizations Directory** — Returns a paginated directory of organizations from Messari with metadata including name, founded date, description, category, sector, location, and external links. *Use when:* Use when an agent needs to look up or enrich organization profiles (e.g. venture capital firms, crypto funds, tech companies) with structured metadata such as founding date, sector classification, geographic location, and links to Crunchbase, LinkedIn, Twitter, or other sources. *Not for:* Do not use for real-time price or market data; use a market data endpoint instead. Not suitable for fetching individual organization details by ID — this returns a bulk directory. **Returns:** Returns a data array of organization objects, each with a UUID, name, optional foundedDate, description, category, sector, location string, and a links array containing named URLs to external platforms such as Crunchbase, LinkedIn, Twitter, and the organization's website. **Example:** `GET https://api.messari.io/funding/v1/organizations` --- ### `fetch-ma-events` **Messari M&A Events** — Returns a list of crypto-industry merger and acquisition events from Messari, including announcement dates, transaction values in USD, deal status, and detailed acquiring/acquired entity profiles. *Use when:* Use when an agent needs structured M&A deal data for crypto and related companies, such as identifying recent acquisitions, deal sizes, announcement dates, or entity details for a specific transaction or market overview. *Not for:* Do not use for token price data, fundraising rounds, or venture capital investments; use a dedicated funding or market data endpoint instead. **Returns:** Returns a data array of M&A event objects each with a UUID, announcement URLs, announcementDate, transactionAmountUSD, status, and full acquiringEntity and acquiredEntity profiles including names, categories, sectors, tags, and external links. **Example:** `GET https://api.messari.io/funding/v1/mergers-and-acquisitions` --- ### `fetch-funding-rounds` **Messari Funding Rounds** — Returns structured crypto and fintech funding-round records from Messari, including round type, stage, amount raised in USD, announcement URLs, funded entity details, and investor IDs. *Use when:* Use when an agent needs deal-level funding data for crypto or fintech projects — e.g., to track recent raises, identify investors in a sector, filter by round stage, or build market intelligence pipelines. *Not for:* Do not use for real-time token price feeds or on-chain transaction data; use a market data or blockchain explorer API instead. Not suitable for equity-only traditional finance deals outside crypto/fintech scope. **Returns:** Returns a JSON object with error=null and a data array of funding-round records, each containing round UUID, announcement URLs, date, type, stage, USD amount raised, funded entity details, and investor ID lists. **Example:** `GET https://api.messari.io/funding/v1/rounds` ---
