Error Handling
try {

} catch (err) {
// Axios/HTTP errors, invalid params, auth issues, etc.
console.error(err);
}
Tips
- Provide a viewerFid when supported to respect mutes/blocks and include
viewer_context. - Keep requests scoped (e.g., use
limit) to improve latency. - Cache results where sensible.
