Payment tools for AI agents with a free plan

The INITE Atlas lists 11. By use, the list opens with Purchase API by Agentcard, Clear Agent, AGIRAILS, Paybond and Bursora.

The pricing page names a free plan, the product is free, or it is open source. Read off the vendor's own page, with the date.

How we read a tool

No votes, no reviews, no vendor claims. Every week a crawler reads each tool's own site and a few public registries, and the words on the card are bands over what it read.

  • Use: visits to the site (estimated), installs from npm and PyPI, presence in Chrome's usage report.
  • Activity: the newest release on GitHub, npm or PyPI; the newest dated page on the site; open roles on a public jobs board.
  • Price: the vendor's own pricing page, read with the date. A figure is printed only when it is on that page.
  • The line and the use cases are written by us from the homepage, one tool at a time, and refused when they repeat the vendor's marketing.

How AI assistants read each site — the reading vendors ask us about — is on each tool's own visibility page.
