🧐 Why has the x402 protocol suddenly become popular? Why is there a huge wealth effect? How can we participate?

I mentioned before:

The future is the era of AI and AI automatic interaction, and the intermediary in between must be Token, not fiat currency—

If you can understand this sentence, you can understand why the 402 protocol is hot, and why the issuance/minting of PING has seen dozens of times in growth.

Because this concept has been brewing for a long time, it is definitely going to develop in the long term, it is changing the underlying protocols of the internet, and it is the foundation for changing the new interaction methods of human society,

And it is not a fleeting phenomenon:

1️⃣ What is the x402 protocol?

It is a standard protocol that incorporates "payment" into the standard process of web pages/APIs.

For example, when you visit a webpage or API that requires payment, the server returns HTTP 402 (Payment Required), telling you how much to pay and which chain/which currency to use (commonly USDC).

After you (or an AI agent) complete the payment, you can request again to get the result.

2️⃣ Why is it important:

Pay-per-use/micropayments, no need to register an account or subscribe;

Machines can pay directly, which is very suitable for AI agents to automatically call data, models, and services;

Instant settlement with stablecoins, providing a unified experience across websites/services.

3️⃣ Representative projects:

PING (Base):

The first token to "participate in minting with x402 and go viral," costing $1 each, successfully obtaining 5,000 tokens, similar to early "inscription" style new offerings, mainly used to verify x402 traffic and settlement paths.

Questflow:

A multi-agent collaboration/orchestration layer that forms "teams" of multiple AI agents to execute tasks, supporting pay-per-use for tasks/calls through x402.

AurraCloud:

An AI agent hosting and monetization platform for developers, compatible with OpenAI/MCP, using x402 for "inference/service pay-per-use."

Meridian:

Backend services for x402 providing "settlement and hosting" (multi-chain collection, settlement routing).

PayAI:

A multi-chain x402 payment and verification service provider, offering ready-made gateways for integrators.

Daydreams (Lucid):

Turning LLM inference and Agent-to-Agent calls into payable resources, allowing users to purchase using USDC through x402.

Gloria AI:

A real-time information/data stream platform open to traders and agents, allowing pay-per-use data retrieval with x402.

Kite AI:

The foundational layer for the "agent internet" (identity + payment + governance), highly compatible with x402 in the long term, leaning towards "chain/foundation facilities."

3️⃣ Summary in one sentence:

x402 = The "pay-as-you-go" standard for Web & Agents; although it is still early, it can already do real things: it can turn any webpage/interface into an instantly payable "payment endpoint."

Currently, the narrative is dominant, and practicality is still in its early stages, but that does not affect speculation, what do you think?
