Solana DAS Routes

DAS routes proxy the standard Solana Digital Asset Standard endpoints to Alchemy or Helius and are gated with x402 exact payment on Solana mainnet.

Conventions

All Solana DAS routes share the same shape:

Path template: POST /v1/x402/solana/{cluster}/{provider}/das/{method}
- cluster ∈ mainnet, devnet
- provider ∈ alchemy, helius
Access mode: exact (paid per call)
Alternate methods accepted on the path: GET, HEAD
Content-Type: application/json
Request body: { "params": { ... } } - named DAS params forwarded directly to the upstream provider
Success body: { ok: true, provider, cluster, surface: "das", method, priceUsd, result }
Payment network: solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp (mainnet)
Payment asset: USDC mainnet mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v (6 decimals)
Rate limit: 10 rps per provider:cluster:das scope

Alchemy does not expose DAS on devnet. DAS routes on Alchemy are available on mainnet only. Helius supports DAS on both clusters.

Prices come from the upstream PAYG schedules:

Alchemy - $0.45 / 1 000 000 CU
Helius - $5 / 1 000 000 credits

Both are rounded up to the nearest micro-USDC. Authoritative values are always reported by GET /v1/catalog and by the 402 challenge envelope.

`getAsset`

`POST /v1/x402/solana/devnet/helius/das/getAsset`	helius	devnet	`$0.000050`	10 credits

Params

Field	Type	Required	Notes
`params.id`	`string`	yes	Canonical DAS asset id (base58).

Example

curl -X POST https://gateway.Ryvo.network/v1/x402/solana/mainnet/helius/das/getAsset \
  -H "Content-Type: application/json" \
