With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability frontera-signal-companies-lookup-77e78d3e ``` Example prompt: Can you look up Weslaco Independent School District in the Frontera Signal companies dataset and show me their recent construction projects and total estimated costs in Hidalgo County? ## When to prefer this Use this endpoint when you need to identify or profile construction companies—owners or design firms—active in South Texas border counties (Hidalgo, Cameron, Starr, Willacy), especially when researching project history, license status, cost estimates, or geographic footprint by partial company name. It is particularly valuable for competitive intelligence, due diligence on contractors, or tracking school district and municipal construction activity in the Rio Grande Valley. ## Known failure modes - Missing required 'name' query parameter returns a validation error - Name too short or too generic may return up to 10 matched company names with truncated results - No matching companies returns an empty companies array - Stale data (over 14 days since weekly update) is flagged in the disclaimer field - Payment failure (x402) returns a 402 response requiring USDC micropayment ## How this service works Use to vet a developer, owner, architecture firm or trade contractor in the Rio Grande Valley, Texas: projects filed since late 2024 (count, total and largest cost, cities, dates, newest projects) and state trade licenses held by the business (A/C, electrical, sign, elevator), current or expired. Pass part of the name (3+ characters). No match is a free 404. Example: "How many projects has this developer filed in the Valley since 2024, and how large was the biggest one?" ## Output Returns a JSON object listing matched companies (up to 10 names) with their role (owner or design firm), cities and counties of activity, state trade licenses, first and last seen dates, project count, latest project details (address, scope, type of work, estimated cost, status), and aggregate cost figures. Also includes dataset metadata such as coverage counties, data freshness, cadence, and disclaimer. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "name" ], "properties": { "name": { "type": "string", "description": "Part of an owner or design-firm name, case-insensitive." } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "properties": { "note": { "type": "string" }, "as_of": { "type": "string" }, "query": { "type": "object", "properties": { "name": { "type": "string" } } }, "source": { "type": "string" }, "cadence": { "type": "string" }, "dataset": { "type": "string" }, "coverage": { "type": "object", "properties": { "counties": { "type": "array", "items": { "type": "string" } }, "registered_since": { "type": "string" } } }, "companies": { "type": "array", "items": { "type": "object", "properties": { "name": { "type": "string" }, "role": { "type": "string" }, "cities": { "type": "array" }, "counties": { "type": "array" }, "licenses": { "type": "array" }, "last_seen": { "type": [ "string", "null" ] }, "first_seen": { "type": [ "string", "null" ] }, "project_count": { "type": "integer" }, "latest_projects": { "type": "array" }, "projects_with_cost": { "type": "integer" }, "largest_project_cost_usd": { "type": [ "integer", "null" ] }, "total_estimated_c … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "note": "Public-record activity: projects filed with the state where the company is the owner or the design firm, up to 10 names…", "as_of": "2026-10-03", "query": { "name": "independent school district" }, "source": "public state construction filing", "cadence": "weekly", "dataset": "companies", "coverage": { "counties": [ "Cameron", "Hidalgo", "Starr", "Willacy" ], "registered_since": "2024-10-01" }, "companies": [ { "name": "Weslaco Independent School District", "role": "owner", "cities": [ "Weslaco" ], "counties": [ "Hidalgo" ], "licenses": [], "last_seen": "2025-12-09", "first_seen": "2025-05-09", "project_count": 9, "latest_projects": [ { "id": "FSP-d28b5d37e3", "zip": "78596", "city": "Weslaco", "name": "Weslaco ISD-Security Vestibule at Joe Calvillo Cate Center", "owner": "Weslaco Independent School District", "county": "Hidalgo", "source": "public state construction filing", "status": "Review Complete", "address": "3601 N.
