Developer Resources
Lead Catalyst publishes a small, unauthenticated discovery API so software agents and integrations can identify the company, understand its services, and locate the correct contact and documentation resources.
API contract
The machine-readable OpenAPI 3.1 specification is available at /openapi.json. The current API base URL is https://leadcatalyst.in, and no authentication is required for its read-only company endpoint.
curl -H 'Accept: application/json' https://leadcatalyst.in/api/companyErrors and rate limits
API errors use JSON with an error object containing stable code, human-readable message, and actionable resolution fields. Unsupported methods return HTTP 405 with an Allow header, and unknown API paths return HTTP 404 as JSON.
Responses describe the active 60-request, 60-second policy with the RFC 9651 RateLimit and RateLimit-Policy fields. Compatibility fields for clients built against earlier drafts are also returned. An HTTP 429 response includes Retry-After. Clients should use the RFC fields rather than hard-code retry timing.
Agent access
The homepage supports content negotiation. Send Accept: text/markdown for a concise Markdown representation, or request the default HTML representation. Both variants return Vary: Accept, Accept-Encoding so intermediary caches keep them separate. Usage guidance and important links are also published in /llms.txt.
