# Moody's RMS > Moody's RMS is the catastrophe risk modeling and risk-data business of Moody's Corporation. It sells peril models (hurricane, earthquake, flood, wildfire, severe convective storm, terror, cyber, pandemic) and the exposure-data infrastructure that property-and-casualty insurers, reinsurers, brokers and capital-market participants use to price, accumulate and transfer catastrophe risk. Its products run on the cloud-native Intelligent Risk Platform, which fronts Risk Modeler, ExposureIQ, UnderwriteIQ, TreatyIQ and Risk Data Exchange. The developer portal is public and readable without a login, but the APIs are tenant-scoped: API keys are issued only to licensed Intelligent Risk Platform tenants, so there is no self-serve signup and no sandbox. > Generated 2026-07-25 by API Evangelist from https://github.com/api-evangelist/moodys-rms ## APIs - [Platform APIs](https://developer.rms.com/platform): ~24 REST API families that automate portfolio management, underwriting and risk-transfer workflows across Risk Modeler, UnderwriteIQ, ExposureIQ, TreatyIQ and Risk Data Exchange.

Keys are issued by a tenant administrator; there is no self-serve signup. - Hosts: regional — `api-use1.rms.com` (Americas) or `api-euw1.rms.com` (Europe). - Idempotency: pass a client-generated UUID in the `x-rms-requestid` header on POST and PATCH. - Pagination: `limit` + `offset`; filtering via `q`/`filter` with `=`, `!=`, `>`, `<`, AND, OR, IN, NOT IN, LIKE, NOT LIKE; ordering via `sort`. Exposure calls also carry `datasource` naming the EDM. - Async: everything expensive is a polled job — no webhooks, no events, no AsyncAPI. - Errors: vendor envelope `{code, message, logId}` in `application/json`; 2,125 documented codes across 106 domain prefixes. Not RFC 9457. - Versioning: URI path (`/v1/`, `/v2/`); calendar releases named `YYYY.MM.`. A superseded version is deprecated immediately and stays live for one year, announced in a `Warning` header. ## Artifacts - [apis.yml](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/apis.yml) - [Authentication profile](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/authentication/moodys-rms-authentication.yml) - [API conventions](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/conventions/moodys-rms-conventions.yml) - [Error-code registry](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/errors/moodys-rms-error-codes.yml) - [Problem types](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/errors/moodys-rms-problem-types.yml) - [Lifecycle](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/lifecycle/moodys-rms-lifecycle.yml) - [Changelog](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/changelog/moodys-rms-changelog.yml) - [Conformance](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/conformance/moodys-rms-conformance.yml) - [Data model](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/data-model/moodys-rms-data-model.yml) - [Domain security](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/security/moodys-rms-domain-security.yml) - [Agentic access](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/agentic-access/moodys-rms-agentic-access.yml) - [Well-known probe record](https://raw.githubusercontent.com/api-evangelist/moodys-rms/refs/heads/main/well-known/moodys-rms-well-known.yml) ## Not published - No OpenAPI for the Platform APIs or Climate On Demand — rendered reference pages plus Postman collections only. - No AsyncAPI, webhooks, event catalog or streaming surface.
