Forward X402

If you need my attention, pay for it.

The problem Forward X402 solves

CEOs & other exposed people usually have an endless list of spam emails of people offering services. Cold outreach is a valid way to create a business but it forces a huge amount of lost time on the receiving end.

Once in a while, one of those emails is actually USEFUL. However, they are always lost in the noise.

Forward X402, fixes this problem by allowing people to pay for access to your email. If someone truly thinks they are worth your time, let them pay for it.

For business people seeking mutiple zeros contracts, paying a small fee upfront is a massive simplification of their sales process. It removes the need to scour the org, to find a lead in, or a warm introduction.

However, not all channels are created equal. Someone writing from LinkedIN might be less likely to be important than someone writing from a private network. To accomodate for that, Forward X402 allows you to define multiple endpoints with different prices, for example:

  • For X, charge 60 $
  • For LinkedIN, charge 100$
  • For private network, charge 10$

If you get too many emails from X, then you can raise your price until the amount of emails manages what you can handle.

No more opportunities lost, no more sales friction. You are worth my time? Prove it, put your money where your mouth is.

Challenges I ran into

  1. I had to create my own implementation of x402 link because python is not yet available as far as I can tell.

  2. Setting CDP is a bit tricky because the key is a multiline script which is a pain in the ass to set up in multiple hosting services which are by default expecting a single-line string.

  3. Setting up a browser wallet to test with base-sepolia is less than ideal. In Metamask you have to jump through multiple hoops until you have that set up easily.

  4. Using wallet connect is very annoying from python-based envs because the plain HTML+js solution is no longer supported. I had to create my own JS and bundle it so it can be imported as a simple script from FastHTML.
