Pink data: x402 vs AP2 vs ACP in numbers, 495K weekly npm downloads vs zero official packages

Описание и применение

x402 доминирует по всем метрикам использования, в то время как AP2 и ACP не имеют официальных SDK и демонстрируют низкую активность разработки, выявляя пробелы в управлении бюджетом и одобрении платежей.

Задача

Developers lack side‑by‑side public metrics to evaluate AI‑agent payment plumbing protocols, making it hard to choose a mature, well‑used option.

Результат

x402 leads by an order of magnitude on all usage metrics; AP2 and ACP lack official packages and have minimal development activity, exposing a gap in budget and approval features across all protocols.

Рабочий процесс

• 1. Clone the Pink-Agentic-Payments/agent-payment-protocols-tracker repo. 2. Run python3 collect.py with a GitHub token to gather metrics. 3. Inspect tracker.csv for per‑protocol GitHub stars, contributors, commits, npm/PyPI downloads, MCP servers, and listed partners. 4. Review the WHAT_NONE_DECIDE.md file to understand budget/approval gaps. 5. Compare results to decide which protocol best meets project needs.

Доказательства

x402's official npm packages get 494,987 downloads a week combined (the sum of its five official packages)

AP2 and ACP have no official package we could confirm

Источник

AP2's spec repo last pushed 2026-06-17. That doesn't necessarily mean the protocol is dead

x402's own spec answers this directly, in its scope section: "Out of Scope: This specification does not include: ... Client-side budget management"
