# Resolve ambiguous ticker query to canonical symbol

`GET /api/v2/quotes/resolve`

Disambiguates ticker queries against a Blob-cached static map of 30+ primary-source publishers (Wikidata + OpenFIGI + per-exchange CSVs) rebuilt biweekly by sugra-ingest. Falls back to upstream /search with name cross-validation for queries the static map does not cover. Use `?strict=true` to skip the upstream fallback (deterministic mode for AI agents).

## Query parameters

- `q` string, required — Ticker symbol (e.g. `BABA`, `9988`, `7203`, `9988.HK`) or company name (`Alibaba`).
- `strict` boolean — When true, return 404 if the static map has no entry (skip upstream /search fallback).

## Response `200`

Canonical Sugra Finance symbol plus exchange / company metadata.

- EnvelopeResolveResponseV2
  - `data` ResolveResponseV2, required
    - `symbol` string, required — Canonical Sugra Finance ticker symbol (e.g., AAPL, 9988.HK, 7203.T).
    - `exchange` string, nullable — Exchange code (NYQ, NASDAQ, HKG, JPX, KSC, etc.).
    - `name` string, nullable — Company / security display name.
    - `confidence` 'high' | 'medium', required — Resolution confidence - `high`: 2+ primary sources agree on the listing, `medium`: single source (typical Sprint 1 baseline) or upstream /search with `/quoteType` cross-validation. The endpoint never returns unverified results, so `low` is not a possible value.
    - `source` string, required — Where the resolution came from: `static_map` | `static_name_index` | `search_verified` | `alias_redirect`. `static_name_index` (Sprint 11) is set when the resolver matched a multi-word company-name query against the prebuilt name index instead of a ticker lookup.
    - `primary_listing` string, nullable — Symbol of the primary listing if `symbol` is an ADR / cross-listing.
    - `us_default` boolean — True when this is the US-default resolution for a bare ticker (e.g., BABA -> NYSE ADR).
    - `alternatives` string[] — Cross-listings (different exchange) of the same security. Empty when the security trades only on one exchange.
    - `share_class_siblings` string[] — Same-exchange share-class peers (e.g. `BRK-B` for `BRK-A`; `GOOG` for `GOOGL`). Empty when the security has no dual-class structure.
    - `company_id` string, nullable — Wikidata Q-ID of the underlying company.
    - `figi` string, nullable — OpenFIGI composite FIGI for the security, when known.
    - `sources` string[] — Source providers that agreed on this resolution (`wikidata`, `openfigi`, `nasdaq_csv`, `hkex_csv`, …).
    - `status` 'active' | 'delisted' — Sprint 10: trading status. `active` = ticker currently trades. `delisted` = at least one signal flagged the listing as no longer trading. Defaults to `active` for blob entries that pre-date the Sprint 10 schema.
    - `delisting_signals` string[] — Source labels that fired the delisted status. `wikidata_p582` = Wikidata curator marked the listing with an end-time qualifier on the canonical's PRIMARY listing (Sprint 10.x.3 narrowed scope from any cross-listing to primary-only - non-primary historical delistings no longer poison status). `sec_absent` = ticker missing from SEC `company_tickers.json` while Wikidata corroborated US-listing. `sec_form25` (Sprint 10.x.7 RE-ENABLED) = SEC daily-index recorded a Form 25 / 25-NSE deregistration for this US bare ticker in the last 30 business days, with per-filing content classification confirming the affected security is common equity (not corporate debt notes / preferred / warrants / depositary-of-preferred). Stronger and ~13 days earlier label than `sec_absent` for the equity case. Empty when status is active.
    - `delisting_end_date` string, nullable — ISO date string. Populated when any time-bearing signal fires: `wikidata_p582` (P582 end-time qualifier) or `sec_form25` (Form 25 filing date). Most recent date wins when multiple signals carry dates.
    - `relisted_at` string, nullable — Sprint 10.x.1: ISO date when SEC daily-index recorded a Form 8-A12B / 8-A12G filing (registration of a new class of securities) for this US bare ticker, AND the listing previously had a Wikidata P582 end-time stamp on its primary listing. Populated only on canonicals where Wikidata previously marked the primary listing as ended; this gate excludes first-time IPOs, uplistings, and new share class registrations from being flagged as relistings. Null when no recent relisting filing exists or no prior P582 evidence supports the relisting interpretation.
    - `listing_date` string, nullable — Sprint 11: ISO date when the security was first listed on its primary exchange. NSE provides this for Indian equities; null otherwise.
    - `series` string, nullable — Sprint 11: NSE trading-series code (`EQ` = cash equity, `BE` = trade-to-trade, `BL` = bulk). Null for non-NSE listings.
    - `group` string, nullable — Sprint 11: BSE trading-group classification (`A`/`B`/`T`). Null for non-BSE listings.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
