SIEM Establishments Search
Search Mexican business establishments in the SIEM directory by commercial name or razón social. Optional filters narrow by state (INEGI code) and SCIAN activity. SIEM is a self-declared directory: registration is voluntary and each establishment chooses which fields stay public, so absence is not evidence of anything. Drill into a result with siem-establishment.
Supports async delivery: set Prefer: wait=N for an inline result, pass callback_url to receive a POST when ready, or poll GET /jobs/{id}.
