market exposes no CLOB outcome tokens

Error message

market exposes no CLOB outcome tokens

What it means

Raised by prediction_market_tool._resolve_history_token when the resolved market object has an empty or missing clobTokenIds list. History is fetched per CLOB outcome token, so a market with no CLOB tokens (not yet deployed to the CLOB, or a negative/closed market migrated away) cannot serve trade history through this path.

Solutions

1. Verify the market actually trades on the Polymarket CLOB (check its page for an active order book)
2. Retry later if the market is new and tokens may not be deployed yet
3. Inspect raw.get('clobTokenIds') in the payload to confirm the field is genuinely empty vs malformed
4. Use a different market or outcome that exposes tokens

def has_clob_tokens(raw: dict) -> bool:
    return bool(raw.get("clobTokenIds"))

try:
    token, meta = _resolve_history_token(identifier, outcome)
except ValueError as e:
    if "no CLOB outcome tokens" in str(e):
        return None  # market not tradeable on CLOB; skip gracefully

When it happens

Trigger: Looking up history for a brand-new market whose CLOB tokens haven't been minted/listed yet; a resolved/resolved-archived market whose clobTokenIds were cleared; a partially populated Gamma payload where the field exists but is empty.

Common situations: Scraping newly-created or draft markets; negative markets that never listed on the CLOB; relying on Gamma data for markets that only exist on another venue.
