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.
Example use cases
Verify Texas business registration status
“I need to check whether 'Bluebonnet Holdings LLC' is an active registered business in Texas — can you pull their SOS file number and status from the Texas Comptroller records?”
Find charter date for due diligence
“We're doing due diligence on a company called 'Austin Growth Capital' — can you find their Texas franchise taxpayer record and tell me when they were chartered and what their organization type is?”
Enrich CRM with Texas business address
“I have a Texas vendor named 'Gulf Coast Supply Co' and I need their official registered address and taxpayer number from the state records to update our CRM.”
Technical details
Endpoint
GEThttps://api.companyrecords-api.workers.dev/api/b2b/texas-sos-business?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
