trade_setups
Top trade setups from the decision engine with defensive-alternates baked in. When the screen is one-sided (>=70% same direction across 3+ picks), the response carries universe_skew = 'bearish' | 'bullish' | 'mixed' AND a regime_ block containing the editorial fallback basket (defensive | cash_heavy | value_tilt | momentum). Each alternative carries strategy label, curated candidates with thesis per name, and a one-sentence rationale. Use the alternative when the primary picks don't fit the user's risk frame — e.g. all-bearish screen on a long-bias capital-allocation query surfaces the defensive basket so the model never has to refuse or invent. The skew counts LONG/SHORT setups only: NEUTRAL setups are unclassified, so a screen of NEUTRAL rows is 'mixed' with no alternative. as_of_ts, book_age_sessions and is_stale give the age of the prediction book the setups come from. Schema is ADDITIVE — primary setups array unchanged from v2.41.
Parameters
Query
limitintegerOptional251 to 500min_convictionnumberOptional00 to 1Response
A 200 is a JSON envelope: ok: true and this endpoint's own fields (see Quant Signals). It carries X-Request-ID, the credit headers (X-Credits-Cost, X-Credits-Remaining, X-Credits-Receipt, X-Credits-Settlement) and the rate-limit headers.
A 200 is billed even when it holds no data (an empty list, null, found: false), so check those fields. Pricing & credits explains the credit headers.
Errors
No error is billed. The body is { "ok": false, "error", "detail", "request_; read the code from error.
| Error | Meaning |
|---|---|
400 invalid_ticker | The request is malformed, for example a ticker that is not a symbol: invalid_ticker, refused before any credit is reserved, with param naming the parameter. Not billed. |
401 unauthorized | Missing or invalid API key. |
402 plan_required | Your plan does not include this tool, you are out of credits, or your workspace's spend cap paused its keys. plan_required names the plan that unlocks the tool; usage_exceeded means the credit balance is spent; spend_cap_reached means the key is paused until the cap resets or is raised: detail names the cap and the reset, cap_usd and resets_at (ISO 8601) carry them, and doc_url links pricing and credits. Not billed. |
403 scope_denied | This API key is limited to some products and this tool is not one of them. product names the tool's product and scopes the key's products. An upgrade does not change it: use a key whose scopes include the product, or change this key's scopes. Not billed. |
404 not_found | No such resource. Not billed. |
422 validation | A parameter is missing, out of range or the wrong type; param names it. Not billed. |
429 rate_limited | Your plan's rate limit is spent for this window. Retry after Retry-After seconds. Not billed. |
503 paid_ | The data could not be served completely right now; retry later. Not billed. |
504 request_timeout | The request ran past the server's time budget; retry. Not billed. |
