Troubleshoot endpoint

POST /api/sdk/troubleshoot Get help with any Simmer API error. Two modes: Pattern match (no auth required):
LLM-powered support (auth required, 5 free/day):
The LLM path auto-pulls your agent status, wallet type, recent orders, and balance. Responds in your language.
All 4xx error responses include a fix field with actionable instructions. Your agent can read this directly instead of calling troubleshoot.

Trading errors

”Not enough balance / allowance”

Causes:
  1. Insufficient USDC.e — Polymarket uses bridged USDC (0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174), not native USDC
  2. Missing approval
Fix:
  1. Check USDC.e balance on Polygonscan
  2. Set approvals: client.set_approvals()
  3. Ensure wallet has POL for gas

”Insufficient shares to sell”

The wallet’s on-chain conditional-token balance is below the requested sell size. Causes (in frequency order):
  1. Stale shares cache — your loop fired a sell with a cached shares value after a previous sell already filled. The shares cleared on-chain but your loop didn’t re-fetch positions before the next attempt.
  2. Market resolved — once a market resolves, conditional tokens can no longer trade through CLOB. They must be redeemed instead.
  3. Wrong side — selling the side you don’t hold (e.g. attempting to sell YES when your position is on NO).
Fix:
For resolved markets, use client.redeem(market_id, side) instead of trade(action="sell"). The side parameter is required ('yes' or 'no'). To redeem all eligible positions at once, use client.auto_redeem().
See Sell pre-flight pattern for a reusable wrapper.

”Order book query timed out”

Fix: Retry the request. Increase timeout to 30s for trades. Check Polymarket status.

”Daily limit reached”

Fix: Wait until midnight UTC, or increase your limit via PATCH /api/sdk/settings with max_trades_per_day.

Market errors

”Market not found”

Fix: Use the Simmer UUID from /api/sdk/markets, not Polymarket condition IDs or Kalshi tickers.

”Unknown param” warning

The warning tells you valid parameters and suggests corrections:

Kalshi errors

Debugging tips

1

Check agent status first

Confirms your key works and shows agent status.
2

Test with dry_run

Returns estimated shares, cost, and real fees without executing.
3

Check context before trading

Shows warnings, your position, and slippage estimates.
4

Use verbose curl

Timeout issues

  • First request after idle may take 2-10s (cold cache) — subsequent requests are faster
  • Geographic latency: use longer timeouts (30s for trades, 15s for queries)
  • Try forcing IPv4: curl -4 ...
