GraveMarket SDK

@solanadeads/gravemarket · version 0.2.4 · install with npm i @solanadeads/gravemarket

This page is generated from the published tarball — it is byte-for-byte the README inside node_modules/@solanadeads/gravemarket at v0.2.4. It is not a summary and it cannot drift.

Read-only TypeScript SDK for the GraveMarket marketplace public API. Wraps public GET endpoints and returns fully typed responses.

• Zero runtime dependencies. Native fetch. Works in Node 18+, browsers, Cloudflare Workers, Deno, and Bun.
• Typed. Full .d.ts for every method and response.
• Cursor pagination. Async iterator helpers for every paged endpoint.

Install

npm install @solanadeads/gravemarket
# or
pnpm add @solanadeads/gravemarket

Requires Node 18+ (uses native fetch and AbortController).

Quick start

import { GravemarketClient } from '@solanadeads/gravemarket';

const client = new GravemarketClient();

// Browse collections — reference by slug or contract address
const page = await client.collections.list({ limit: 25, chain: 'solana-mainnet' });
const first = page.data[0];
console.log(first.name, first.slug, first.contract_address, first.floor_price);

// Fetch an NFT — by mint address (Solana) or `contract:tokenId` (EVM)
const item = await client.items.get('<mint-address>');

// Just the rarity rank/score/tier
const rarity = await client.items.rarity('<mint-address>');
// { rank: 12, score: 184.2, tier: 'legendary', total_supply: 5000 }

Legacy Graveyard*-prefixed exports (e.g. GraveyardClient, GraveyardApiError) remain available as aliases for backward compatibility with existing integrations.

Options

new GravemarketClient({
  apiKey: 'gm_...',                          // recommended — get one at https://gravemarket.io/developers
  baseUrl: 'https://api.solanadeads.com',    // default
  timeoutMs: 30_000,                         // default 30s
  fetch: customFetch,                        // optional — defaults to globalThis.fetch
  headers: { 'X-My-Header': '1' },           // optional default headers
});

API keys

The SDK works anonymously by default, but applying for an API key is recommended — anonymous access will be disabled in the future. Generate one at gravemarket.io/developers and pass it via the apiKey option. The SDK sends it as the X-API-Key header on every request.

When the API responds with HTTP 429, the SDK throws a GravemarketRateLimitError exposing retryAfterMs, limit, and remaining:

import { GravemarketRateLimitError } from '@solanadeads/gravemarket';

try {
  await client.collections.list();
} catch (err) {
  if (err instanceof GravemarketRateLimitError) {
    await new Promise((r) => setTimeout(r, err.retryAfterMs ?? 1000));
    // retry
  }
}

Smart Money

Track what the top wallets are doing right now.

// Live whale activity feed (cursor-paginated)
const { feed, next_cursor } = await client.smartMoney.feed({ chain: 'solana-mainnet', limit: 25 });
for (const row of feed) {
  console.log(row.side, row.collection?.name, row.price_usd, row.from_address);
}

// Top whales by metric over period
const { rankings } = await client.smartMoney.leaderboard({ metric: 'realized_pnl', period: '30d' });

// Collections with the most net whale inflow
const { inflows } = await client.smartMoney.inflows({ period: '7d' });

Wallet PnL

Per-wallet profit/loss with FIFO lot tracking.

const summary = await client.walletAnalytics.pnl(wallet, { period: '30d' });
console.log(summary.realized_pnl_usd, summary.unrealized_pnl_usd, summary.win_rate_pct);

// Paginate the underlying lots (open + closed)
const lots = await client.walletAnalytics.pnlLots(wallet, { closed_only: true, limit: 100 });

Trust

Wash-trade fingerprints for collections and wallets.

// Top trustworthy / suspicious collections
const cleanest = await client.trust.collections({ sort: 'cleanest', period: '7d', limit: 20 });
const sus     = await client.trust.collections({ sort: 'most_suspicious', period: '30d' });

// Wallet wash-rate (returns null pct for wallets under 10 trades)
const t = await client.trust.wallet(wallet);
console.log(t.wash_pct_30d, t.in_cluster);

Adjusted volume toggle

Platform / collection analytics accept volume: 'reported' | 'adjusted' (default adjusted). Adjusted volume excludes sales flagged by the wash-trade detector.

const reported = await client.analytics.platform({ period: '7d', volume: 'reported' });
const adjusted = await client.analytics.platform({ period: '7d' }); // adjusted by default

Collection-level analytics

// Daily series + stats snapshot + holder history for a collection
const a = await client.analytics.collection('apes-collection', { period: '30d' });

// Side-by-side comparison of up to 4 collections
const cmp = await client.analytics.compare({ collection_ids: 'a,b,c', period: '7d' });

// 7×24 liquidity heatmap (UTC) per chain × window
const h = await client.analytics.heatmap({ chain: 'solana-mainnet', metric: 'volume', days: 30 });

// Net flow / buyer-seller mix / hold-time histogram for a collection
const f = await client.analytics.flow('apes-collection-uuid', { period: '7d' });

Identifying entities

Reference entities by their public identifiers:

Entity	Identifier
Collection	slug or contract_address
Item (NFT)	token_address (Solana mint), or contract_address:token_id (EVM)
Wallet	wallet_address
Affiliate	affiliate_code
Trait	trait_type + trait_value

Pagination

Cursor-paginated endpoints return { data, cursor, hasMore }. Several namespaces expose *All methods returning async iterators:

for await (const batch of client.collections.listAll({ chain: 'solana-mainnet' })) {
  for (const c of batch) console.log(c.slug, c.floor_price);
}

Or use paginate() directly:

import { paginate } from '@solanadeads/gravemarket';

for await (const batch of paginate((cursor) =>
  client.activity.list({ cursor, type: 'sale', limit: 100 }),
)) {
  // ...
}

Error handling

import { GravemarketApiError, GravemarketTimeoutError } from '@solanadeads/gravemarket';

try {
  await client.items.get('does-not-exist');
} catch (err) {
  if (err instanceof GravemarketTimeoutError) {
    // request timed out
  } else if (err instanceof GravemarketApiError) {
    console.error(err.code, err.status, err.message);
  } else {
    throw err;
  }
}

The SDK auto-unwraps the { success, data } envelope. If the server returns success: false, a GravemarketApiError is thrown with the server's code and message.
