Plans & Pricing

The API is offered on the plans below. Access is enforced by the x-api-key gate described in here. All plans grant full access to every endpoint, plans differ on included usage, throughput, and support.

The API comes in two flavours, both covered by the same plan:

Plans are measured in credit allowances, and each credit is the unit of API usage. Each successful request costs 1 credit, be it a GraphQL query or a REST call (e.g. /morphoCache/lite, /liquidations/positions). Heavier aggregated endpoints may cost more than 1 credit. Failed requests (4xx/5xx) are not charged.

Each plan includes a monthly credit allowance that resets at the start of every billing cycle; usage beyond the allowance is billed at the Pay-as-you-go rate ($0.002 / credit). On the Pay-as-you-go plan you are billed only for what you use, with no monthly commitment.

How API keys work

  • Send your API key on every request as x-api-key

  • Paid plans are billed monthly; an expired key returns 401 until renewed.

  • Keys are issued and renewed by the Mystic team, contact us to choose a plan and get one.
