Use JSON only when the page needs a number
If a citation or prefilled calculator link would answer the reader faster, use that instead.
Calculator API
Use JSON when a link is not enough.
These read-only endpoints are for pages that need a lightweight planning result, not a whole calculator UI. Use them for comparison tables, partner resources, and research notes, then keep the full calculator close so readers can change the assumptions.

These endpoints return planning estimates from query-string inputs. They do not store personal data, create checkout sessions, approve a build, or replace the full calculator assumptions and safety notes.
Start here
Use the API for a preview, not the final answer.
Every response includes the matching calculator URL, assumptions URL, and caveat text. Keep those links near the result so readers know what changed the number.
I need a live estimate
Open a sample request when another page needs a number that can update from query values.
Browse endpointsI need to explain the math
Use the assumptions page when a result needs formulas, defaults, and caveats beside it.
Review calculator assumptionsI only need links
Use the citation hub when an API call would be overkill for a guide, club page, or newsletter.
Open citation hubTreat every response as a planning estimate
Defaults and guardrails keep requests from failing, but they do not replace rig-specific inputs.
Keep the calculator link next to the output
Readers need a path back to editable inputs, caveats, and assumptions before acting on the number.
How to use it
Keep the number attached to its next step.
The API is best when a page needs a quick planning result without loading the full calculator UI. Show the estimate, explain the caveat, and link to the calculator so readers can adjust the inputs.
1
Pick the endpoint group
Start with the kind of problem instead of scanning every JSON path.
2
Open the sample request
Each endpoint includes a realistic URL you can test before changing values.
3
Keep the handoff visible
Show the estimate with the caveat and link readers to the full calculator.
Endpoint library
Pick the problem area, then open the sample request.
Query values use the same guardrails as the interactive calculators. If a value is missing or outside the expected range, the endpoint falls back to the calculator default so the page can still show a cautious estimate.
