# Pricing

Crypto APIs uses a credit-based subscription model. Each plan includes a monthly credit allowance, and every API call consumes credits — so the plans scale by usage rather than by a fixed request count. Billing is monthly or annual (annual saves roughly 16%). See [/pricing](/pricing) for the authoritative, current plans and the full feature matrix.

## Plan tiers

- **Free** — no cost and no credit card required, with a starter monthly credit allowance and lower throughput limits; suitable for evaluation and small projects.
- **Starter** — a paid entry tier with a much larger credit allowance, higher throughput, and unlimited Blockchain Events, HD Wallets, and Address History.
- **Scale** — the most popular tier, with a larger credit allowance and higher throughput for growing production workloads.
- **Pro** — a high-volume tier with the largest standard credit allowance, top throughput, and dedicated support.
- **Enterprise** — custom pricing for institutions needing unlimited scale, compliance, and dedicated support.

## How the credit model works

A plan's monthly credit allowance is not a simple request count. Credit cost varies by endpoint and by blockchain/network, and there are additional ongoing and one-time charges:

- **Per-request cost** — every call consumes credits; the amount depends on the endpoint and chain.
- **Monitoring fees** — daily credits to keep a synced address, xPub, or blockchain-event subscription monitored.
- **Execution/processing fees** — one-time credits per indexed transaction or per callback sent.

Exceeding a plan's soft throughput limits is billed as pay-as-you-go overage. Because per-endpoint costs differ, comparing plans by raw credit count alone is not meaningful — check the per-endpoint credit costs on the [developer portal](https://developers.cryptoapis.io/) for exact figures.
