Weekly Intel is the Sunday newsletter where people building x402 payment infrastructure read independent measurements of the rails: settlement flows, facilitator behaviour, endpoint conformance. Every figure has a published counting method. Sponsors buy a clearly labelled place next to those numbers, and nothing else. That restraint is the product.
A newsletter this focused earns attention by not selling it off in pieces. There are two sponsor positions in each issue, there will never be a third, and every sponsored element carries a visible SPONSOR label a reader can spot in under a second.
One line: “This week's ledger is brought to you by [you]”, followed by up to 60 words of your copy, one link, and your logo. One Presenting sponsor per issue, no exceptions. You may change your copy every issue.
Up to 100 words and one link, headed SPONSORED · Infra Note, placed after the main measurement block and before the closing section. One per issue. Built for a concrete technical message rather than a slogan.
The market that buys x402 infrastructure fits, to a first approximation, in one room, and a meaningful share of it reads this newsletter. You are not paying for a thousand random impressions; you are paying for density. Deliberately, every package fits on a company card without procurement.
Founding rate: the first two agreements signed by Sept 30, 2026 get 20% off and a permanent “Founding Sponsor” credit in the archive. An honest discount for buying from a newsletter selling sponsorship for the first time, not a fake countdown.
Measurement guarantee: the media kit states our audience as a measured figure, method published, window dated. If the median of unique opens during your paid term falls below 80% of that figure, we extend your placement pro-rata, free. We sell measurements, so our own reach is guaranteed by one, not by adjectives.
Audience numbers: measured the way we measure everything, and published in the media kit with a date and a method, including the honest caveat that email opens are inflated by Apple's privacy features. We do not round up. Ask for the current media kit by email.
Payment by invoice, Wise transfer, or USDC, your choice. Sponsor copy is due the Thursday before the Sunday send. All communication is async and written: info@smartflowproai.com.
This is not fine print. It is the reason the audience opens the email, and therefore the reason your logo means something here. It ships with every offer and it is not negotiable.
Readers open this newsletter because the numbers in it cannot be bought. That is the asset you are sponsoring. To protect it, for the readers and for you, these rules are absolute:
A clearly labelled slot, exactly as specified in the media kit: your copy, your link, your logo. You may change your copy every issue. That is the entire product.
If our ledger shows something unflattering about a sponsor, we publish it exactly as we would for anyone else. We have already published findings that flagged the highest-volume entities in our own catalog as overwhelmingly wash traffic. A sponsor logo does not change the query.
Every sponsored element carries a visible SPONSOR label and is visually boxed. A reader skimming on a phone can tell in under a second what is paid and what is measured.
We decline sponsors whose products our data shows misleading users, and we may terminate a placement, with a pro-rata refund, if that changes mid-term. We have publicly flagged scam infrastructure before; we will not take its money.
The current sponsor list is public on the archive page. Pricing is public on this page. There are no side deals.
An audience this small only has value if it trusts what it reads. Every rule above exists to keep that trust, which is precisely what makes your logo here worth more than the same logo in a bigger, looser publication.
Weekly Intel is written by the operator of an independent x402 settlement ledger, assembled daily from public chain data. The counting methods behind every published figure live in a public methodology repository, and the open-source endpoint validator we maintain is used by third-party operators, including outside contributors adding fixtures for their own endpoints. When one of our own numbers has been wrong, the correction ran at the top of the next issue. Sponsors get the same treatment as the data: stated plainly, labelled honestly.
