Pricing

Pay for what you call.

Four ways to call base-transaction-decoder, from free to a flat monthly rate. No accounts anywhere — even the recurring plan cancels itself through Stripe, not us.

Free
$0

50 calls per IP address, every day — shared by everyone behind one address. No signup, no wallet, no API key.

Pay per call
$0.02 / call

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>

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.

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.
