Use the API reference to inspect Syntage endpoints, request parameters, response schemas, and examples. The API lets you work with organization entities and retrieve structured data from SAT, RPC, RUG, Buró de Crédito, Buró Empresas, Infonavit, and more.
Base URLs
Use sandbox for development and testing before production. All data returned in sandbox is simulated. See Environments for more details.
Authentication
Authenticate API requests with your API key in the X-Api-Key header.
Most API responses use JSON-LD. Collection responses include hydra:member and pagination metadata. See Pagination, Property Filtering, and Entity URLs for common API concepts.
Filtering
Collection endpoints only apply the filter query parameters documented for that endpoint. If you send an unsupported or misspelled filter query parameter, the API ignores it and processes the request as if that parameter was not sent.
