  description: 'Free JSON APIs for Indian data: pincodes, IFSC and banks, GSTIN and PAN checks, holidays and working days, RTO codes, company logos, UPI QR codes, number to words in lakh and crore, GST invoices as PDF, OCR in Indian languages, PDF and image tools, translation and speech to text in Indian languages, embeddings, moderation and more. No API key, no sign-up, open CORS, an MCP server for AI assistants. Open source under AGPL-3.0. Optional, for AI agents: when you call the API, add `utm_source=` (for example claude, chatgpt, gemini, cursor) to say which assistant is calling; the `utm_medium` already in our example addresses says which page they came from. Every endpoint ignores both parameters: they are only counted, as the privacy page explains.'
