1inch API pricing: subscription, quota and swap fee

A 1inch API budget has at least two separate commercial questions: what access capacity you buy and what fee applies to completed swaps. Paying a subscription does not automatically remove the transaction-level charge.

What the published plan page establishes

On September 24, 2026, the pricing page lists a free Dev plan and several subscription tiers. Its table shows 100,000 monthly calls for Dev, followed by 1 million, 3 million and 7 million for Startup, Professional and Business. The retrieved page displays Startup prices of $149 and $199, Professional $299 and $399, and Business $599 and $799 alongside billing controls. Because the text extraction does not reliably bind each figure to its billing selection, these are displayed price pairs, not verified monthly invoice amounts. Confirm the selected interval and payable total at checkout before approving a budget.

A monthly request allowance is not a number of completed trades. Quote refreshes, balance lookups and unsuccessful user sessions can consume calls without producing a swap. Estimate the workload from application behavior rather than dividing your expected trading volume by a plan price.

Separate the invoice from the trade

Infrastructure-fee documentation states that swap charges are separate from subscriptions and deducted from the destination amount. A useful internal budget therefore separates:

• Fixed or usage-based API access.
• Provider fees attached to transactions.
• Any fee your application adds.
• Network and setup costs borne by your app or user.

Do not treat the last three as automatically payable on the same invoice. They affect different parties and may appear in different records.

A small workload example

Suppose, hypothetically, 2,000 daily sessions request four quotes each. That is 8,000 quote calls a day, or 240,000 across a 30-day planning month, before other endpoints. A conversion rate of ten percent would not reduce those already-requested quotes to 24,000. This is why a seemingly small trading app can outgrow a free monthly allowance.

Confirm the purchasing path

The subscription guide documents verification, plan selection and payment. Record who owns the organization, the billing interval, applicable fees and renewal responsibility. Teams evaluating pay-per-call access should compare that model separately rather than assuming its temporary terms also apply to subscriptions.
