R.E. Merrill & Associates

R.E. Merrill & Associates, Inc. is a Texas industrial pump distributor and manufacturers' representative (founded in Houston in 1987 by Ron Merrill Sr., led since 2020 by Ron Merrill Jr.; based in Wimberley, TX) that applies, quotes and supports 13 pump lines — Vanton thermoplastic pumps (exclusive Texas representative for 30+ years), Grundfos dosing and multistage pumps, Continental progressing cavity pumps, DP Pumps, Pinnacle-Flo, Vertiflo, Simtech, TF Seals, Garbarino, GreenPumps, Pemo, Victor and Walrus — for chemical processing, semiconductor, water/wastewater, boiler and petrochemical service. It publishes one machine-callable capability: a deterministic pump line finder that takes a pumping duty (fluid, flow, pressure or head, service) and returns which represented lines fit, citing the manufacturer catalog page for the smallest covering model, then hands off to a human engineer for quotation. The capability is exposed as an unauthenticated REST endpoint (POST https://www.remerrill.com/api/line-finder) and as an Agent2Agent v1.0 agent (JSON-RPC 2.0 at /api/a2a) with a JWS-signed agent card at /.well-known/agent-card.json, a published JWKS, and an llms.txt as its developer documentation. No pricing is returned by the API; quotes come from an engineer.

R.E. Merrill & Associates publishes 3 API contracts indexed on the APIs.io network, including A2A API, Line Finder API, and 1 more. Tagged areas include Industrial Pumps, Pump Selection, Industrial Equipment, Chemical Processing, and Manufacturing.

R.E. Merrill & Associates’ developer surface includes documentation, support, engineering blog, authentication, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/remerrill-com: open an issue to ask a question, or submit a pull request to add artifacts.
