R.E. Merrill Pump Line Finder API is one of 2 APIs that [R.E. Merrill & Associates](https://apis.io/providers/remerrill-com/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Pump Selection, Industrial Pumps, Chemical Processing, and Agent-Native. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Deterministic pump line selection over plain HTTP: POST a duty ({fluid (required), concentrationPct?, temperatureF?, flowGpm? or flowGph?, pressurePsi? or headFt?, service? (transfer|feed|sump|slurry|boiler)}) to /api/line-finder and receive which represented pump lines fit and why — per-family matching-model counts, a rationale naming the smallest covering model with its source catalog and printed page, the items the endpoint deliberately leaves to a human engineer (fluid compatibility, concentration, temperature, service fit), the curated-vs-consult-REM coverage of the 13 lines, and an rfqUrl prefilling the quote form. Curated coverage is Grundfos dosing (116 model envelopes) and Continental progressing cavity (105); other lines return consult-REM. Unauthenticated, stateless, no rate limits documented. The provider publishes no OpenAPI; the one under openapi/ was generated by API Evangelist from the provider's llms.txt, agent card and live responses (2 operations).

## Operations (2)
