Tank Utility

Tank Utility makes LTE-connected propane tank monitors, mobile apps, and a read-only API that surface their data. Its sensors report tank fuel level, temperature, and battery state so homeowners get low-fuel alerts and fuel marketers can route deliveries by real consumption instead of guesswork — Tank Utility says this drops the same gallons in up to 40% fewer deliveries. The Tank Utility API lets an account exchange credentials (HTTP Basic) for a short-lived token, list the monitors on the account, and read each device's latest reading. Tank Utility is owned by Anova.

Tank Utility publishes 2 API contracts indexed on the APIs.io network: Authentication API and Devices API. Tagged areas include Propane, Tank Monitoring, IoT, Fuel Delivery, and Telemetry.

The Tank Utility catalog on APIs.io includes 1 Spectral governance ruleset.

Tank Utility’s developer surface includes authentication, CLI, support, engineering blog, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities 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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
