Delilah API is one of 2 APIs that [Delilah](https://apis.io/providers/delilahusa-com/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Legislation, Government, and Public Data. The published artifact set on APIs.io includes API documentation.

Delilah's REST legislative data API (service "delilah-api") serving bills, roll-call votes, legislators, committees, hearings, sessions, statutes and 2026 election data for all 50 states, D.C. and Congress under /v1 (e.g. GET /v1/bills, /v1/legislators, /v1/votes/{roll_call_id}), as named in the tool descriptions of Delilah's own MCP server. Requests require an X-API-Key header; keys are requested at https://delilahusa.com/developers/request and the developer docs sit behind the delilahusa.com login. The host root advertises an OpenAPI document at /openapi.json, which returned 404 on 2026-11-05, while /v1/openapi.json returned 401 (missing X-API-Key), so no contract is publicly readable.
