You are not charged for the Apify platform usage, but only a fixed price for specific events. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## EMMA Municipal Bonds Scraper Scrape municipal bond securities from **EMMA** (Electronic Municipal Market Access) — the official SEC-designated disclosure platform for the US municipal securities market, operated by the Municipal Securities Rulemaking Board (MSRB). ### What It Does This actor navigates [emma.msrb.org](https://emma.msrb.org) — the authoritative, freely accessible repository of US municipal bond data. For each bond security it extracts: - **Issuer Name** — name of the municipal bond issuer (city, county, state agency, utility district, etc.) - **Security Description** — series name and bond type (e.g. "SR-MEASURE BB", "GO BONDS SERIES A") - **State** — full state name and two-letter state code - **Principal Amount** — total face value of the bond offering (e.g. $4,785,000) - **Coupon Rate** — annual interest rate paid to bondholders (e.g. 5%) - **Maturity Date** — date when the bond principal is repaid (MM/DD/YYYY) - **Dated Date** — date from which interest begins to accrue (MM/DD/YYYY) - **Offering Price** — initial price as a percentage of par value (e.g. 102.167%) - **Offering Yield** — yield to maturity at the offering price (e.g. 1.53%) - **Credit Ratings** — whether Fitch, Moody's, S&P Global, and KBRA ratings exist for the bond - **Security URL** — direct EMMA page link for full prospectus and disclosure documents ### Use Cases - **Fixed-income research** — build structured databases of municipal bond offerings by state, issuer, or yield - **Credit analysis tools** — identify rated vs. unrated bonds and cross-reference rating agencies - **Investment screening** — filter bonds by state, maturity horizon, coupon level, or principal size - **Public finance analytics** — track municipal borrowing activity by jurisdiction over time - **Compliance and due-diligence** — verify offering details against EMMA's official disclosure records ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `states` | array of strings | `["CA"]` | Two-letter US state/territory codes to scrape (e.g. `["CA", "NY", "TX"]`). Accepts all 50 states plus DC, GU, PR, VI. | | `maxItems` | integer | 100 | Maximum number of bond records to return. Set to 10 for a quick test. | ### Output Each item in the dataset contains: ```json { "issuerName": "ALAMEDA COUNTY TRANSPORTATION COMMISSION", "securityDescription": "SR-MEASURE BB", "stateName": "California", "stateCode": "CA", "principalAmount": "$4,785,000", "couponRate": "5%", "maturityDate": "03/01/2023", "datedDate": "07/14/2022", "offeringPrice": "102.167%", "offeringYield": "1.53%", "fitchRating": "", "moodysRating": "", "spRating": "", "kbraRating": "", "securityUrl": "https://emma.msrb.org/Security/Details/A60477195F2E8C188281BB5745B77C8EE", "scrapedAt": "2026-06-05T14:55:54.680Z" } ```` Rating fields contain `"rated"` if a rating from that agency exists for the bond, or an empty string if unrated. MSRB renders the actual rating values as images for licensing reasons — the presence/absence signal is available from the data. ### About EMMA EMMA is operated by the Municipal Securities Rulemaking Board (MSRB) under SEC designation as the official disclosure repository for US municipal securities. All data is sourced directly from official MSRB disclosures. The actor scrapes only publicly available data — no authentication or subscription is required. *** *For issues or feature requests, contact * # Actor input Schema ## `sp_intended_usage` (type: `string`): Please describe how you plan to use the data extracted by this crawler. ## `sp_improvement_suggestions` (type: `string`): Provide any feedback or suggestions for improvements. ## `sp_contact` (type: `string`): Provide your email address so we can get in touch with you. ## `states` (type: `array`): List of two-letter US state/territory abbreviations to filter bonds by (e.g. \["CA", "NY", "TX"]).
