  • CONNSKILL Growth ServicesCONNSKILL GmbH & Co. KG · agent.connskill.com
    Card live

    Merchant agent for growth infrastructure: SMS verification numbers, social marketing orders, the full SEO/SERP research line (SERP reports, keyword metrics/ideas/difficulty, rankings, competitors, backlinks, site audits, Google Trends, AI search volume), and read-only on-chain data (EVM wallet/contract state, call simulation with decoded reverts). Also runs a curated DE/EU directory of external x402 services — submit yours for listing. Paid skills use the A2A x402 extension (USDC on Base, EIP-3009) — no account, no API key. Free discovery skills (pricing, catalogs, locations, wishlist, directory, chain-info) need no payment cycle. Prices are catalogue information, not a purchase authorization. Some current prices could not be confirmed. Service data handling: https://agent.connskill.com/privacy.

  • 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. Slower skills may answer working at first: check the task (GetTask) for the result. 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.
