news_sentiment_history

Daily aggregated news sentiment for one company back to 2000 — mean event sentiment (ESS), event count and mean relevance per day from the news-analytics archive (2000-2025) stitched with the live feed. Call it for long-run sentiment regimes or news reaction around past events; for today's headlines use the /news routes instead. The live feed arrives in monthly batches: data_through is its newest day (the archive's end for a window inside the archive), is_stale is true once a month is due (due_through) and not held, days after data_through are not held yet (coverage.not_covered_after), and a window starting after it answers warning window_after_coverage, which means not held yet, not no news. When the archive or live tail cannot be read it returns 503 upstream_unavailable (error_code warehouse_read_failed; not billed), never an empty series.

Response

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