# Data coverage & availability

> Inspect Voltfin's stablecoin, DeFi TVL and tokenized asset coverage, working source endpoints and the scope of planned institutional services.

Markdown copy of https://voltfin.vercel.app/coverage · also as [JSON](https://voltfin.vercel.app/coverage.json), [CSV](https://voltfin.vercel.app/coverage.csv)

## Know what you can use today.

Open a working application, inspect its source and understand its limits. Managed customer APIs and institutional services are identified separately.

Available: Four public-data apps, source receipts, CSV/JSON exports and notebook continuation.

## Research applications

Data is read when you open a view or request a refresh. Upstream availability and publication cadence apply.

| Application | Source | What it measures | Coverage boundary | Open |
| --- | --- | --- | --- | --- |
| USDC across chains | DefiLlama + public RPC | Reported circulating tokens; separate USD distribution; selected contract totalSupply | All chains reported by DefiLlama. Contract spot checks cover curated deployments, not every issued or bridged contract. | https://voltfin-studio.vercel.app/markets/usdc |
| Stablecoin explorer | DefiLlama + public RPC | USD-pegged asset distribution; USDT/USDC dated supply history | Provider-reported circulation. Authorized, issued and minted supply remain distinct. | https://voltfin-studio.vercel.app/markets/stablecoins |
| DeFi TVL monitor | DefiLlama | Chain TVL, public history and global protocol rankings | Provider-defined USD TVL. A chain filter selects protocols active there; their reported TVL is still global. | https://voltfin-studio.vercel.app/markets/tvl |
| Tokenized asset monitor | Public RPC + issuer references | BUIDL, OUSG and USDY supply on selected deployments | Exact token/share counts from contracts. No NAV, asset backing or global AUM is inferred. | https://voltfin-studio.vercel.app/markets/rwa |

## Working app endpoints

These endpoints support the research apps. They are public source proxies with receipts, not a contracted customer Data API.

- **Protocol rankings**: Normalized DefiLlama protocol data and its source receipt. `GET https://voltfin-studio.vercel.app/api/llama/protocols`
- **USDC circulating supply history**: Up to 366 dated source observations, with token and USD values separated. `GET https://voltfin-studio.vercel.app/api/llama/stablecoin-supply/2`
- **USDT circulating supply history**: The same bounded history format, with a request and response hash. `GET https://voltfin-studio.vercel.app/api/llama/stablecoin-supply/1`

Successful responses can be cached for up to ten minutes. Their source fetch time is retained. These routes have no customer accounts, commercial quotas or contractual service levels. Other supported contract and API reads run directly in the browser.

## Defined in the roadmap. Not yet available to purchase.

- **Managed Data API** (planned): Canonical snapshots, customer API keys, dataset versions, delivery quotas and measured freshness.
- **Historical computation** (planned): Quoted archive jobs, resumable backfills, spending caps and an auditable usage ledger.
- **Organization controls** (planned): Shared workspaces, roles, private data access and audit logs. Additional controls will follow agreed pilot requirements.

Managed ingestion and customer billing are not operational in the current product. No enterprise SLA or compliance certification is claimed. Public-source history and current app exports remain free.

### Proposed commercial model

These are planning prices, not offers available for checkout. Institutional engagements require an agreed dataset, coverage, delivery volume and support scope.

- **Studio Pro**: $49/month with 4,000 managed-work credits, once implemented.
- **Data API**: Developer: $99/month. Production: $499/month. Delivery limits and licensed sources are scoped separately.
- **Archive jobs**: $25 per 2,500-credit pack, with capped quotes for new managed work.
- **Institutional services**: Proposed contract pricing for the platform, delivery and support, plus metered work.
