## How to call it through Zero

```sh
zero fetch --capability frontera-signal-permits-weekly-502c6873
```

Example prompt: Pull the Frontera Signal weekly permits data for Hidalgo and Cameron counties from 2026-W35 through 2026-W39 so I can see how commercial permitting has been trending over those five weeks.

## When to prefer this

Choose this endpoint when you need granular, city-level building permit data specifically for Hidalgo County or Cameron County in South Texas on a weekly basis. It is especially useful for construction market intelligence, real estate pipeline analysis, or border-region economic research. Prefer this over generic permit databases when you need structured, fresh, machine-readable data with staleness indicators for this specific geography.

## Known failure modes

- Invalid ISO week format (e.g. '2026-39' instead of '2026-W39') may return a 400 or empty result
- Requesting future weeks returns no rows
- Stale flag set to true when data has not been refreshed within 14 days for weekly cadence
- Null count or value_usd fields indicate data was not reported for that city-week
- Payment failure (402) if x402 micropayment header is missing or insufficient

## How this service works

Use when you need building-permit activity for Rio Grande Valley cities (McAllen, Edinburg, Pharr, Mission, Weslaco, Brownsville, Harlingen and others) by ISO week and permit class, to judge local construction demand before a lending, supply or market-entry decision. DARK means the city did not publish that week.

## Output

A JSON object containing an array of rows, each representing permit activity for a specific city-week combination, including permit class, count, USD value, data freshness indicators (as_of, age_days, stale, backfill), county, and source metadata. Also includes query echo, total rows returned, series name, publisher, schema version, and a data disclaimer.
