prices_history

Survivorship-bias-free daily price history — archive daily closes, returns, volume and cumulative split adjustment factors (cfacpr/cfacshr) 2000-2024, stitched with live daily bars 2025→today, plus the delisting record. ONE basis on every row: prc is the price as traded, prc/cfacpr is on today's share basis (vol*cfacshr likewise); price_basis says which live rows were restored to as-traded, and a step no split explains is refused (503 price_series_discontinuous), never served. ret is the total return (dividends on their ex-date) and retx the price return, on archive and live rows alike; if the live dividend record cannot be read, live ret is null and returns_basis says why. Rows before 2000 carry null cfacpr/cfacshr; an adjustment block then names them, and ret/retx stay valid. interval defaults to 1d — omit it or pass interval=1d. A missing grain used to 504; the route is daily-only. A small limit (e.g. 5) returns the newest live daily bars without scanning the archive. Intraday intervals 422 to /api/v3/tape/bars/{ticker}?date=YYYY-MM-DD. Not /fundamentals/prices (vendor OHLCV) and not /reference/history (identifier timeline).

Response

A 200 is a JSON envelope: ok: true and this endpoint's own fields (see Market Data). 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_id" }; read the code from error.

ErrorMeaning
400 invalid_tickerThe 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 unauthorizedMissing or invalid API key.
402 plan_requiredYour 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_deniedThis 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 unknown_tickerNo data source lists this ticker, active or delisted: the market-data listing and the security master both say it does not exist. param names the parameter. Not billed. Best-effort: it is answered only when the route itself found nothing, and after 20 lookups of new symbols per API key per minute the route's own answer stands.
422 validationA parameter is missing, out of range or the wrong type; param names it. Not billed.
429 rate_limitedYour plan's rate limit is spent for this window. Retry after Retry-After seconds. Not billed.
503 paid_data_unavailableThe data could not be served completely right now; retry later. Not billed.
504 request_timeoutThe request ran past the server's time budget; retry. Not billed.
