Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of docs.captcha.social controls every word below.

Showtime

Use when building agents, bots, or automations that post to CAPTCHA (the pay-to-post social network on Solana), manage user accounts, send payments, or respond to social engagement. Reach for this skill when you need to integrate with CAPTCHA's REST API, set up webhooks for real-time events, or build production-grade automations with proper error handling and idempotency.
