Engagements

An independent third party who tells you what a transaction actually did, and what it could not check.

We examine your own on-chain activity and hand you a written finding with the raw evidence attached, in a form you can reproduce yourself. Scoped work, agreed before it starts. Not a licence, and not a seat.

Settlement forensics

What a transaction or a set of them actually moved, which fields were controlled by the transaction’s author, and which checks could not be completed against it.

Attribution audit

For a set of addresses, what can be established from the chain and what cannot. The second list is the one most reports leave out.

Reconciliation

Your own record of what happened, compared against what the chain shows, with every difference itemised and evidenced.

A clean result is a result. You are paying for the check, not for the finding, payment is due whether what we find is a problem or nothing at all. An analysis that only gets paid when it finds something has a reason to find something.

Also available: our written record of a settlement failure we hit ourselves, a fixed document rather than an engagement on your data.

What this is not

You receive JSON and a written artifact. Not a signed attestation, and not an opinion you can hand to a regulator. It is our reading of public chain data with the evidence attached so you can check every step of it yourself, which is the part that makes it worth having, and also the limit of what it is.

Start a conversation See the tool first

Tell us what you want checked and we will tell you whether we can check it. If we cannot, we will say so rather than scope around it. How paying works, no deposit, no card on file, nothing recurs.

Or call it yourself

The API, priced per call.

Unchanged, and still the fastest way to find out whether any of this is worth a conversation. No account on our side in any of these.

50 calls every day per IPv4 address or IPv6 /64, shared by everyone behind it. No signup, no wallet, no API key.

USDC on Base via x402. An agent pays and retries automatically; a human can pay the same way from the playground, once the free calls run out.

0200 Pass
$9 one time

10,000 calls over 30 days. A bearer token, not an account, nothing to cancel, because nothing recurs.

Setup is one URL, pasted into any MCP client:

https://api.0200project.com/mcp/btxp_<your token>
Pay with card, $9

Or pay with a Base wallet:

0200 Developer
$9 / month

The same 10,000 calls as the Pass, renewing automatically instead of being bought again by hand. Comes with a managed URL, and a rotatable key once that's built. Cancel anytime through a Stripe-hosted portal; there is no account on our side to close.

Pay with card, $9/month Manage or cancel

Have a card and no wallet at all? The Apify Store listing bills $20 / 1,000 calls, the same $0.02 per call, directly through Apify. It's a working card path today, no wallet required.

Why do the Pass and Developer plan cost the same?

Deliberately. The usage is identical: 10,000 calls, 30 days. The Pass is bought by hand and expires; Developer renews itself and adds a managed URL. Pick whichever matches how you want to think about it, a top-up, or a subscription.
