## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability querylines-admitted-market-insurance-rate-filings-api-da0b521a
```

Example prompt: Pull admitted-market rate filings from Texas and California for homeowners coverage from January 2023 to December 2024, filtered to insurers with at least a 10% rate change — I want to see which carriers are pushing big hikes that might be driving business into the E&S market.

## When to prefer this

Use this endpoint when you need raw admitted-market rate filing data from specific state regulators (TX, MS, CA, WA) to track insurer pricing behavior, identify carriers with large rate hikes, monitor potential E&S market spillover, or conduct insurance market research. Prefer this over the aggregated rate-activity index endpoint when you need individual filing records rather than summary statistics.

## Known failure modes

- Invalid state code returns 400 with validation error
- Date format not YYYY-MM returns 400 bad request
- No filings match the filter criteria returns empty result set
- min_change value out of reasonable range may return no results
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Rate limiting or quota exceeded returns 429

## How this service works

Admitted-market insurance rate filings (Texas TDI open data, Mississippi MID bulletins, California CDI rate-filing approvals, and Washington OIC annual reports) -- a leading indicator of surplus-lines (E&S) growth: large admitted-market rate hikes or withdrawals tend to push business into the E&S market. Filter by state, coverage line, insurer, minimum rate change, or date range. $0.10 per query. Free sample: /v1/rates/sample. Docs: https://api.querylines.com/openapi.json

## Output

A list of rate filing records from state insurance regulators (TX TDI, MS MID, CA CDI, WA OIC), each including insurer name, state, coverage line, rate change percentage, filing date, and approval status. Up to 100 results by default, filterable by state, line, insurer substring, minimum rate change, and date range.
