Error Handling
async function fetchWithRetry(url, options, maxRetries = 3) {
for (let i = 0; i < maxRetries; i++) {
const response = await fetch(url, options);
if (response.status === 429) {
const retryAfter = response.headers.get('Retry-After') || 60;
await new Promise(r => setTimeout(r, retryAfter * 1000));
continue;
}
if (!response.ok) {
const error = await response.json();
throw new Error(`API Error ${response.status}: ${error.message}`);
}
return response;
}
throw new Error('Max retries exceeded');
}
Common errors:
401: Invalid/missing API key402: Insufficient credits403: Endpoint requires PRO subscription429: Rate limit exceeded (wait and retry)404: Address not indexed (>100k transactions)
Cost Optimization
- Batch addresses:
?addresses=0x123,0x456,0x789(1 credit vs 3) - Use free endpoints:
/v1/statusand/v1/creditscost nothing - Filter on server: Use
networks,txTypesparams vs client filtering - Cache results: Portfolio cached 1 minute, transactions 10 minutes
- Check status first: Avoid unnecessary syncs
Common Patterns
Multi-wallet portfolio
const addresses = ['0x123...', '0x456...', '0x789...'];
const response = await fetch(
`https://api.octav.fi/v1/portfolio?addresses=${addresses.join(',')}`,
{ headers: { 'Authorization': `Bearer ${apiKey}` } }
);
Paginated transaction fetch
async function getAllTransactions(address) {
const transactions = [];
let offset = 0;
const limit = 250;
while (true) {
const response = await fetch(
`https://api.octav.fi/v1/transactions?addresses=${address}&limit=${limit}&offset=${offset}&sort=DESC`,
{ headers: { 'Authorization': `Bearer ${apiKey}` } }
);
const batch = await response.json();
if (batch.length === 0) break;
transactions.push(...batch);
offset += batch.length;
if (batch.length < limit) break;
}
return transactions;
}
Smart sync workflow
async function smartSync(address) {
// Check status first (free)
const [status] = await fetch(
`https://api.octav.fi/v1/status?addresses=${address}`,
{ headers: { 'Authorization': `Bearer ${apiKey}` } }
).then(r => r.json());
const lastSync = new Date(status.transactionsLastSync);
const minutesSinceSync = (Date.now() - lastSync) / 1000 / 60;
if (minutesSinceSync > 10 && !status.syncInProgress) {
await fetch('https://api.octav.fi/v1/sync-transactions', {
method: 'POST',
headers: { 'Authorization': `Bearer ${apiKey}`, 'Content-Type': 'application/json' },
body: JSON.stringify({ addresses: [address] })
});
}
}

Use it when building blogs, documentation sites, or content-heavy Vite + React applications to ensure type safety and automatic content validation. It covers everything from Vite plugin configuration and MDX compilation to deployment optimization and schema validation.
polymarket
MetaThis skill enables developers to build applications with the Polymarket prediction markets platform, including API integration for trading and market data. It also provides real-time data streaming via WebSocket to monitor live trades and market activity. Use it for implementing trading strategies or creating tools that process live market updates.
creating-opencode-plugins
MetaThis skill helps developers create OpenCode plugins that hook into 25+ event types like commands, files, and LSP operations. It provides the plugin structure, event API specifications, and implementation patterns for JavaScript/TypeScript modules. Use it when you need to intercept, monitor, or extend the OpenCode AI assistant's lifecycle with custom event-driven logic.
sglang
MetaSGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
