Say you lead a small team that has to pick an API to build on in construction. Somebody pulls up the Construction tag on APIs.io and points out that the two top-ranked providers are Procore and Bentley Systems. Procore is at 63.9 on the Kin Score and Bentley is at 62.9. Both are rated strong. The gap is 1.0 point. You'd be tempted to call that a tie and move on, or to pick Procore because it's first. The post says to do neither, and it explains why.
Start with what the score measures. The Kin Score covers the public API surface, not the product and not the company. The Construction tag holds 314 providers, and its 312 scored members average 15.6. Both of these sit more than 47 points above their own category, so either one is far ahead of the typical provider in the tag.
Next, look at what you'd actually be buying. These are different purchases. Procore is the construction management platform, the system of record for a job: project management, financials, quality and safety, field productivity. Bentley is infrastructure engineering software for roads, bridges, rail, water and energy, and it reaches developers through iTwin, a digital twin platform. One runs the job. The other models the asset.
Access differs too. Bentley publishes its developer pricing: a free Community tier with 100 credits a month, and a Standard tier at $199 a month with credits at $1.20. Signup is self-serve, and it states its limits at 500 calls a minute on Community and 5,000 on Standard. Procore's pricing page gives no numbers and asks you to get a custom quote. The catalog still lists Procore as freemium, which the pricing page doesn't support, so the catalog is filing that as a correction. On rate limits, Procore flags limiting on 3,292 of 3,296 operations in a 60-minute window per token, with three response headers, but the catalog holds no numeric limit for it.
The real difference in scale is the one thing the score doesn't reward. Procore has 534 API pages carrying 3,391 operations. Bentley has 87 pages and 299 operations. Procore declares one API and the catalog splits it by resource group, so treat operations as the honest unit. If you need Budget, Change Orders, Daily Logs or Drawings, that's Procore. If you need Changesets, Briefcases or iTwin Visualization, that's Bentley.
Now the facets. Bentley wins five of the six. It leads on discoverability, 78.6 to 67.9. It leads on contract quality, 51.8 to 46.5, on operational transparency, 65.8 to 47.4, on developer ergonomics, 82.1 to 77.9, and on access clarity, 64.5 to 60.5. Those five carry 0.88 of the weight. Procore wins contract governance, 79.1 to 13.6, at a weight of 0.12. That one 65.5-point gap is worth about 7.9 on the composite, more than Bentley's five wins combined. It is why Procore leads the six-facet base 61.7 to 60.3. The conditional layers then move Procore up 2.2 and Bentley up 2.6, which leaves the 1.0 point you saw.
Here is the turn in the post, and it's about the catalog's own record. Procore's governance wasn't built by Procore. Its ruleset is marked as generated by API Evangelist tooling, and its conformance declaration and vocabulary are marked as derived. All of them are dated 2026-10-20, the day its profile was rebuilt and its score moved up 34.6 points. The page records 0.0 first-party catalog points for Procore, against a floor of 24.0 for Bentley. So the lead reflects how recently the catalog profiled each company, not a governance program at Procore. These pages are still scored on rubric 0.24.0. The current rubric, 0.25.0, discounts credit for derived work, and the post says this order should not be expected to survive it.
The same caution applies to Bentley's extras. Its page lists 8 Arazzo workflows, 149 collections and a 319-operation agentic access profile, but all 8 workflows and the access profile were derived by the catalog. They show what the catalog did for Bentley, not what Bentley ships.
Agent readiness holds up better. Procore scores 45.6 and is agent-ready. Bentley scores 24.8 and is agent-aware. Procore's contract carries verified examples and an idempotency token, though on only 9 of 1,667 mutating operations, and its band was gated down from agent-native because its error semantics are derived rather than a stable published envelope. Two Procore lights carry caveats. Its protected resource metadata comes from a trust-center subdomain and describes a vendor's service, not the Procore API. The documented MCP server on its page conflicts with the catalog's own probe, which found none. Both are being filed.
What you take away is simple. If you're building on the job, with budgets, change orders and daily logs, Procore is the only one with that surface, and its 3,391 operations are the reason to pick it. If you're building on the model of an asset, Bentley is the only choice, and it's easier to start with because of public prices and self-serve access. Don't choose on a 1.0-point gap that the catalog's own files created.
