Supported Indices

This page is the canonical reference for all searchable indices available in embed's APIs. Each index represents a content type with its own set of filterable, sortable, and searchable fields.

When new indices are added, this page is updated first. Individual API reference pages link back here.

Index Summary

Service Coverage by Index

Not all services are available for every index. This table shows what works today.

Key:

• Search — filter_and_sort, boost, frequent_values all work
• Semantic Search — requires text embeddings; not yet indexed for Kalshi and token-items
• Features — ML enrichment via /features/v1; wallet indices are used as user profiles via forUser, not as item indices
• Scoring Models — trained reranking models; currently only Polymarket has one
• Ranking — the /ranking/feed endpoint works with any items regardless of index; this column indicates whether trained ranking models exist for personalization

Farcaster Items (farcaster-items)

Social posts from the Farcaster protocol.

Filterable Fields

Sortable Fields

Numeric: score_popular, score_trending, score_like, score_comment, score_share, score_reaction, score_spam, score_not_ok, num_like, num_comment, num_share, num_follower, num_following, user_score_spam, text_length, user_events_num, user_events_per_day

Date: item_creation_timestamp

Polymarket Items (polymarket-items)

Prediction market contracts from Polymarket.

Filterable Fields

Sortable Fields

Numeric: best_ask, last_trade_price, liquidity, liquidity_num, spread, volume, volume_24hr, volume_1wk, volume_1mo, volume_1yr, volume_num, one_hour_price_change, one_day_price_change, one_week_price_change, one_month_price_change

Date: created_at, updated_at, end_date, start_date, game_start_time

Polymarket Wallets (polymarket-wallets)

User wallets and profiles from Polymarket.

Filterable Fields

Sortable Fields

Numeric: volume, pnl, events_per_day

Date: updated_at

Zora Coins (zora-coins)

Creator coins from the Zora platform.

Filterable Fields

Sortable Fields

Numeric: num_buy, num_sell, zora_price_in_usdc, zora_market_cap, zora_market_cap_delta_24h, zora_total_supply, zora_unique_holders, zora_total_volume, zora_volume_24h, user_events_num, user_events_per_day, user_score_spam, video_duration

Date: zora_created_at, zora_updated_at

Kalshi Items (kalshi-items)

Prediction market contracts from trading Kalshi on Solana through DFlow contracts.

Filterable Fields

Sortable Fields

Numeric: volume

Date: created_at, updated_at, start_date, end_date

Additional Fields (available in _source, not filterable)

Note: AI labels (ai_labels_low, ai_labels_med, ai_labels_high) are populated on finalized markets. Active markets may have null AI labels until they are processed.

Limitations: Semantic search (/search/semantic) is not yet available for kalshi-items — text embeddings have not been indexed. Use filter_and_sort or boost instead.

Kalshi Wallets (kalshi-wallets)

User wallets and profiles from trading tokenized Kalshi markets on Solana through DFlow contracts.

Filterable Fields

Sortable Fields

Numeric: pnl, volume_quote, volume_outcome, markets_traded, events_per_day

Date: last_trade_time, updated_at

Feature Support: AI Labels are available for Kalshi items. Social Affinity, Trader Affinity, and Content Similarity features are in progress. The Features API (/features/v1) does not yet support kalshi-wallets as a user index — use group_boost on kalshi-wallets fields for search-level personalization instead.

Token Items (token-items)

Multi-chain token data covering Base, Ethereum, and Solana. Contains price, volume, liquidity, and holder data for 76,000+ tokens.

Filterable Fields

Sortable Fields

Numeric: price_usd, total_liquidity_usd, volume_usd_24h, volume_usd_1d, volume_usd_1h, holders_count, price_diff_pct_1d, price_diff_pct_1h

Date: last_updated

Additional Fields (available in _source)

Filter Notes

• Use match (not term) for chain, symbol, and name — these are analyzed text fields
• Use term for token_address — exact match on the contract address
• total_liquidity_usd, volume_usd_* fields may be null for low-activity tokens — use not_null filter to exclude them

Example: Top Base tokens by holders

{
  "index": "token-items",
  "size": 20,
  "sort_by": { "field": "holders_count", "order": "desc" },
  "include": [
    { "filter": "match", "field": "chain", "value": ["base"] },
    { "filter": "numeric", "field": "holders_count", "operator": ">=", "value": 100 }
  ]
}

Example: Tokens with significant price movement

{
  "index": "token-items",
  "size": 20,
  "sort_by": { "field": "price_diff_pct_1d", "order": "desc" },
  "include": [
    { "filter": "numeric", "field": "holders_count", "operator": ">=", "value": 50 },
    { "filter": "numeric", "field": "price_usd", "operator": ">=", "value": 0.0001 }
  ]
}

Limitations: Semantic search (/search/semantic) is not yet available for token-items. Use filter_and_sort with match filters on name or symbol instead.

Upcoming Indices

The following indices are planned and will follow the same {chain}-items / {chain}-wallets pattern:

Field definitions for these indices will be published here as they become available.
