Pay for Alchemy | Mehbit virtual card

What is Alchemy?

Alchemy is a web3 developer platform run by Alchemy Insights, Inc. It gives developers reliable access to more than 100 blockchains through node and RPC APIs, WebSockets, trace and debug APIs, plus data APIs for tokens, NFTs, transfers and prices, webhooks and wallet tools.

Usage is measured in compute units (CUs). Every API method has a fixed CU cost, so a simple call costs fewer CUs than a heavy one, and your bill follows the CUs your apps actually use.

Alchemy’s paid self-serve plan, Pay as You Go, is billed to a card. A Mehbit virtual debit Mastercard topped up with USDT was accepted there and the payment went through.

Alchemy has three plans. Free includes 30 million CUs a month at up to 300 CU per second (about 15 requests a second), with 5 apps and 5 webhooks. Pay as You Go charges a flat $0.52 per million CUs for all usage, with no upfront commitment, and includes 10,000 CU per second (about 300 requests a second), 30 apps, 100 webhooks, premium endpoints and priority support. Enterprise is custom-priced, with volume discounts and signed SLAs.

If you need more throughput on Pay as You Go, each extra block of 5,000 CU per second costs $160 a month, up to 30,000 CU per second in self-serve. As an example from Alchemy’s own calculator, 270 million CUs in a month costs $140.40. Note that moving to Pay as You Go ends the free allowance: every CU is billed from zero.

Billing is incremental. Alchemy charges your card automatically each time your usage reaches a threshold, starting at $50 for new accounts and stepping up through $100, $200, $500 and on to $3,000 as payments succeed, and bills whatever is left at the end of the month. When you upgrade, Alchemy also places a temporary $5 pre-authorization hold to check the card; it is not collected and its payment processor, Stripe, usually releases it within 7 days.

This is why the card side matters. Pay as You Go needs a card with automatic collection, so the Mehbit card must hold enough balance whenever a threshold charge arrives. If a payment fails, Alchemy gives a two-day grace period and then moves the account to the Free tier. You can cap your spending with a usage limit in dollars or CUs in Billing Settings; when the limit is reached, service stops.

There is no cancel button: to stop paid usage you downgrade to Free in Billing Settings, which takes effect at the start of the next billing cycle, after paying any open invoice. A usage limit of $0 stops charges immediately. Alchemy’s terms say fees are non-refundable; refunds are only considered case by case through [email protected].

On the Mehbit side, issuing a virtual card takes about 5 minutes. You keep your funds in USDT, move the amount you need onto the card (a 5% card-load fee applies, and each wallet deposit costs 2 USDT), then let Alchemy charge the card. Each card transaction costs $0.35 from your wallet, declines included, so fewer, larger threshold charges are cheaper than many small ones.

Why local cards get declined at Alchemy

Many local bank cards are not enabled for international online payments, or their bank refuses foreign merchants. Merchants abroad charge cards through global payment processors, so a domestic-only card is often declined even when it has enough balance.

Alchemy payment FAQ

Can I pay for Alchemy with a virtual card?

Yes. We tested Alchemy with a real Mehbit card — the card was accepted and the payment went through. Issue a Mehbit virtual debit Mastercard, top it up with USDT, add it in the Alchemy dashboard and upgrade to Pay as You Go.

How much does Alchemy cost?

The Free plan includes 30 million compute units a month. Pay as You Go costs $0.52 per million compute units with 10,000 CU per second included; more throughput costs $160 a month per extra 5,000 CU per second. Enterprise is custom-priced.

What is the $5 charge when I upgrade?

It is a temporary pre-authorization hold that Alchemy uses to verify your card. It is not collected, and Stripe usually releases it within 7 days. Make sure your Mehbit card has a few dollars on it before you upgrade.

When does Alchemy charge my card?

Automatically, each time your usage reaches a billing threshold (starting at $50 for new accounts), plus a final charge for the remainder at the end of the month. Keep enough balance on the card so these charges do not fail.

How do I stop paying for Alchemy?

Downgrade to the Free plan in Billing Settings; it takes effect at the start of the next billing cycle. To stop charges immediately, set a usage limit of $0. Pay any open invoice first.

Tips for paying Alchemy

Start on the Free plan: 30 million CUs a month is plenty to build and test before you upgrade.

Fund the Mehbit card before you upgrade. Alchemy places a temporary $5 verification hold on the card.

Keep a buffer on the card: charges arrive automatically each time usage reaches a billing threshold, and a failed payment drops you to Free after two days.

Set a usage limit in Billing Settings so a busy app cannot run up a bill larger than your card balance.

Check CU costs per method in Alchemy’s docs: heavy calls such as logs or traces use far more CUs than simple reads.

Rates in Alchemy’s help articles sometimes differ from the pricing page; confirm the current per-CU price on alchemy.com/pricing before you plan a budget.
