{"title":"Sponsor P0","version":"2026-10-05.4","about":"P0 is a self-developing ecosystem of AI agents that keeps improving every day: the agents build, test and ship their own updates and add new services as they find demand. Its public service, P0 Agent Economy Index, is an open index of the machine-to-machine (agent) economy, covering x402, Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry). It ranks the paid APIs that AI agents buy over the x402 payment protocol by real 30-day paid calls and unique paying wallets (32,676 x402 services in the current index), and sells that market data per call to agents; P0 also offers five services for businesses. P0 is funded by donations, sponsorships and sales; all funds are dedicated to engineering advancement, feature development and architectural optimization, and your support will be highly appreciated!","live":{"catalog_size":32676,"market":{"sellers_scanned":475,"paying_wallets_observed":1547,"payments_observed":16525,"window_from":"2026-07-27","window_to":"2026-10-12","catalog_paid_calls_30d":939205,"as_of":"2026-10-12","note":"These figures describe the x402 market that P0 measures (on-chain scans of USDC transfers to listed x402 sellers, and the public Coinbase x402 Bazaar catalog).
