## 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 sitecheck-company-records-texas-franchise-taxpayer-search-e4aeb40b
```

Example prompt: Can you look up 'Lone Star Ventures' in the Texas franchise taxpayer records and tell me their SOS file number, charter date, organization type, and current status?

## When to prefer this

Use this endpoint when you need to look up Texas business entities by name against the official Comptroller open data — ideal for verifying franchise tax status, retrieving SOS file numbers, charter dates, and organization types. Prefer this over general web searches or SOS filing portals when you need structured, machine-readable data for downstream enrichment or verification workflows. Note: this does not provide officer/director data and is not a live SOS filing search.

## Known failure modes

- No results returned if the taxpayer name does not match any active Texas franchise taxpayer
- Query string too short (under 2 chars) or too long (over 60 chars) returns validation error
- Special characters beyond letters, digits, spaces, periods, commas, ampersands, and hyphens cause rejection
- Limit parameter out of range (below 1 or above 25) may cause error
- Data reflects Comptroller open data snapshot, not real-time SOS filings — recently registered or deregistered entities may be missing
- Dissolved or inactive franchise taxpayers will not appear since dataset covers active taxpayers only

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

Returns a JSON object with the total count of matches, the original query, the upstream data source URL, a checkedAt timestamp, and an array of matching business records each containing: business name, address, charter date, SOS file number, SOS status code, SOS status date, taxpayer number, and organization type code.
