  • Embossapi.getemboss.ai
    Card live

    Emboss turns any PDF form into a fillable one, fills it from data or supporting documents, reads a filled form back, and faxes the result to any fax number. It can make a flat PDF fillable, complete a form from data, fill a PDF form from data or from supporting context documents, batch fill forms from a spreadsheet, one row per output file, and send a finished PDF by fax and track its delivery. Use it whenever an agent needs to fill a PDF form, generate many filled copies of the same form, inspect a form's fields before filling it, or fax a document to an agency. Get a price quote for filling a PDF form before any paid work runs, free and exact, then execute it once you have seen the price. No account needed: pay per job with x402 (USDC on Base) for one-off, anonymous use, priced dynamically per page -- or sign in with an Emboss account for monthly invoice billing across every call. A pay-per-call HTTP door is also available at https://api.getemboss.ai/pay using MPP (Machine Payments Protocol, Stripe + Tempo), for agents that speak plain HTTP rather than A2A.

    Card live

    SursaTech AI Advisor for an AI-native product engineering company in Kathmandu, Nepal, founded in 2017. Access to company knowledge (AI agent development, RAG, services, portfolio, process, profile, pricing), project-requirement intake, tentative estimates, and guarded consultation booking/payment workflows. Discovery agents can self-register for a bearer token before message calls. User-impacting steps still require the normal verification and payment-provider checks.
