api record

Frontera Signal sells construction data for the Rio Grande Valley, Texas, per call over x402: USDC on Base, no account or API key. These tools are free and read-only. Start with list_endpoints, read a real answer with get_sample, then use how_to_pay to check your parameters and get the exact URL and price. get_free_series returns the latest 4 weeks of each weekly series at no cost. Payment happens on the HTTP API with an x402 client, never through these tools.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_endpoints unknown never probed

    List every paid Frontera Signal endpoint before you spend anything. Covers Rio Grande Valley, Texas construction data: permits, building-input prices, housing supply, labor, commercial projects filed with the state, company track records, filed cost per square foot, material shelf prices and the weekly briefing. Each entry has the price per call in USDC, what the call returns, an example question, its parameters with valid values and a free sample URL. Free.

  • get_sample unknown never probed

    Get a real answer from one paid endpoint for free, exactly as a paid call returns it, so you can check the fields, dates and coverage before you pay. Pass the endpoint key from list_endpoints, such as snapshot, projects or series-permits-weekly.

  • how_to_pay unknown never probed

    Get the exact URL to call for a paid answer, with its price, network and asset. Pass the endpoint key and the query parameters you plan to send; they go through the same free check the API runs before payment, so a query that would be refused or come back empty shows up here. This tool never calls the paid endpoint and never pays. Payment is x402: no account or API key, USDC on Base.

  • get_free_series unknown never probed

    Get the latest 4 weeks of a weekly Rio Grande Valley series for free: permits-weekly (building permits by city), cost-basket-weekly (building-input prices), absorption (housing supply), labor-ranges (labor and financing conditions) or calls (graded forecasts). Each row carries its week, as_of date and status. The full history is a paid endpoint; how_to_pay with series-<name> gives its URL and price.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 9ae736cdb439c6a5.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9ae736cdb439c6a5/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
