With the growth of the x402 ecosystem, maintaining the ecosystem page is no longer scalable. We've decided to sunset the ecosystem page in lieu of other ecosystem aggregators, and we're closing this PR.
To help with discovery going forward, you may want to submit your project to a few community-maintained x402 directories, including:
x402scan.com
Agentic.Market
Pay.sh
app.ampersend.ai/discover
Thank you for the submission and for contributing to the x402 ecosystem. We truly appreciate your support and participation!
