tape_bars

Intraday minute bars for one equity from the API's own capture (~10.5k tickers, extended hours included, each bar labelled pre / regular / post). Use when an agent needs REAL intraday price/volume history — how a ticker traded through an event, VWAP context, or a finer-grained chart than daily bars. Archive begins 2026-05-10; pass date=YYYY-MM-DD (or start+end, max 5 trading days), each a New York calendar day. 1m is the native grain; 5m/15m/1h are resampled server-side. Split-adjusted to today's share basis by default (adjust=none for as traded; adjustment lists the splits and the date they are recorded through). The daily-bar tool serves prices and volume as traded, so before a split adjusted minute volume is the ratio times its volume: compare with adjust=none. limit keeps the most recent bars and reports what it cut (truncated, n_available). Volume is the real-time capture's, not reconciled with late corrections. An empty answer carries empty_reason; a symbol neither the market-data listing nor the security master knows is a 404 unknown_ticker.

Response

A 200 is a JSON envelope: ok: true and this endpoint's own fields (see Tape & Intraday History). 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.

This table lists what the spec declares for this route. Error responses lists every code FIRM sends, with when to retry.
