API reference & data
The endpoint list and coverage table below load live from the API
itself, so they can't drift from what's actually deployed. If your
browser can't reach api.querylines.com (or has
JavaScript off), each section falls back to a direct link to the
raw data.

Data semantics
Source attribution
Every response, free or paid, carries a source field
naming the exact publication a figure came from (for example,
"FSLSO FL Monthly Premium Report, June 2026"). Facts
are extracted statistics, not republished report content.
report_date and restatements
Stamping offices revise published figures (cancellations, backouts,
late filings). QueryLines never overwrites a fact when that
happens: a restatement creates a new row carrying the publication
date it came from in report_date, and queries default
to the latest report_date for each period. Pass an
explicit report_date query param to pin a response to
a specific historical publication instead.
data_as_of
The most recent period actually covered by the response, which can
trail report_date for annual/summary endpoints that
blend partial-year monthly data with a prior full-year annual
report. Check data_as_of before treating a total as a
complete year.
Building with OpenAPI-consuming tools
https://api.querylines.com/openapi.json is a
standard OpenAPI 3.1 document. Custom GPTs, and any agent
framework that consumes an OpenAPI spec to generate tool calls,
can point at it directly. The three free endpoints
(/v1/premium/sample, /v1/coverage,
/v1/lines) work out of the box with no extra
configuration. The paid endpoints are reachable the same way but
return an x402 payment challenge instead of data until the calling
tool can settle one; see Pay per query.
