## Credits and paying

One credit is 0.005 USDC of usage, the price of the cheapest call. Every paid call uses its per-call price in credits: a launch check or a swap preflight uses 1, a market snapshot 2, a batch 3, CLMM range stats 4, and a deep token, holder, wallet or pool analysis 6. The exact cost of each tool is in the [tool reference](https://dexra.dev/docs/tools).

- **Free**: 100 credits a day once the email is confirmed. Batches and launch feeds longer than an hour are paid per call.
- **Pro**: 5,000 credits a day for 49 USDC per 30 days, with a 3-day free trial.
- **Scale**: 100,000 credits a day for 99 USDC per 30 days.
- **Pay per call**: no account. The first request answers `402` with a `Payment-Required` header (base64 JSON listing the accepted payments: USDC on Solana, amount, recipient). Sign a USDC transfer for one of them and repeat the request with it in a `Payment-Signature` header; the answer carries the settlement in `Payment-Response`. Any x402 client library does this for you.

Past a plan's daily credits, calls go on per call over x402, so an agent is never cut off. Counts reset at 00:00 UTC. Plans are paid in USDC from a Solana wallet in the [cabinet](https://dexra.dev/app/plans).
