agentcash

AgentCash is a skill that lets an agent call any x402/MPP payment-protected API without API keys or subscriptions, using a crypto wallet that pays per request in USDC on Base, Solana, or Tempo. It solves the problem of agents needing paid third-party capabilities (research, enrichment, scraping, image/video generation, email, phone calls, hosting, jobs, travel) without pre-provisioning accounts and keys for each provider — instead a single wallet settles micro-payments on success only.

The workflow is driven through an `npx agentcash@latest` CLI: check wallet balance, get funding addresses or a guided funding flow, redeem invite codes, then pick a service origin (or `search` when none fits), `discover` its endpoints and pricing, `check` a specific endpoint's request/response schema, and `fetch` to make the paid or authenticated call. It ships a catalogue of first-party 'stable*' origins covering people/company enrichment, web search and scraping, social-media data, AI image/video, file and site hosting, email inboxes and subdomains, AI phone calls and numbers, job search, and travel, plus an `add` command to persist any discovered origin as a lightweight skill.

Target users are agent builders who want turnkey pay-per-call access to a broad marketplace of APIs. Two characteristics warrant caution rather than alarm: the skill autonomously spends real cryptocurrency funds from a wallet on each request, and the underlying services include capabilities (large-scale web/LinkedIn scraping, email sending, automated phone calls, contact/email enrichment) that are legitimate but dual-use and could be misused for spam or bulk data collection. The skill itself is a payment broker to legitimate providers, with payments settling only on successful (2xx) responses.
