# Pricing

SolProbe is **pay-per-call** in USDC. No subscription, no minimums, no monthly fee — you pay only for the calls you make. Prices are **identical across every** [**access path**](/access-paths/access-paths.md) (x402, OpenClaw, Virtuals ACP, browser) and on both rails (Base and Solana).

| Service       | Price     | Endpoint                                       |
| ------------- | --------- | ---------------------------------------------- |
| Quick scan    | **$0.02** | `POST /scan/quick`                             |
| Market intel  | **$0.20** | `POST /market/intel`                           |
| Deep dive     | **$0.50** | `POST /scan/deep`                              |
| Trade quote   | **Free**  | `POST /trade/quote`                            |
| Trade execute | **$0.15** | `POST /trade/execute` (charged on commit only) |

All amounts are in USDC (6 decimals). Free, unpaywalled routes — `/health`, `/trade/status`, `/trade/pairs`, `/trade/currencies`, and all [discovery surfaces](/reference/discovery-and-identity.md) — cost nothing.

{% hint style="info" %}
Prices are authoritative at the live `402` challenge and in [`/openapi.json`](https://api.solprobe.xyz/openapi.json) (`x-payment-info`). If this page ever disagrees, trust the live endpoint.
