# Search editorial content

> Search 0xinsider editorial content by keyword. Returns backend-owned learn, glossary, comparison, research, and trading-strategy items with canonical URLs. Opaque ranking scores are not exposed.

Search 0xinsider learn, glossary, comparison, research, and strategy content by keyword. Use this endpoint to link a term in your product to the 0xinsider article for that term.

## Read the results

* `q` is required. It must be 1 to 256 characters before whitespace trim and non-empty after trim.
* `limit` is 1 to 50 with a default of 10.
* Each item carries `content_id`, `kind`, `slug`, `title`, `excerpt`, and `url`. `url` is the canonical first-party link.
* `kind` is `learn`, `glossary`, `comparison`, `research`, or `strategy`.
* The result is one bounded page. `has_more` is `false`, and `next_cursor` and `total` are absent.
* Ranking scores are not exposed. Keep the returned order.
* The 200 response has no `ETag` and no response cache.

  description: >-
    Follow provider-exposed large-trade activity from Polymarket and Kalshi.
    Polymarket wallet-attributed trades can add grades, P&L, strategy, and
    diagnostic-score context when sufficient source data exists; Kalshi public
    prints remain anonymous, and fields can be null or unavailable. Normal API
    requests use a 30-second server timeout that returns HTTP 408 Request
    Timeout with an empty body when exceeded. Public REST /api/v1/* endpoints,
    excluding /api/v1/mcp, use Bearer-token based non-credentialed browser CORS:
    any Origin may call with Authorization, Content-Type, If-None-Match,
    Idempotency-Key, and Mcp-Session-Id request headers. Remote MCP at
    /api/v1/mcp is non-credentialed, but still validates Origin against the
    0xinsider/localhost allowlist per MCP Streamable HTTP DNS-rebinding
    guidance. Successful browser CORS preflight responses advertise
    Access-Control-Max-Age: 86400. Browser JavaScript may read RateLimit-Limit,
    RateLimit-Remaining, RateLimit-Reset, the legacy X-RateLimit-Limit,
    X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After, ETag, X-Request-Id,
    X-Request-Cost, X-Batch-RateLimit-Limit, X-Batch-RateLimit-Remaining,
    X-Batch-RateLimit-Reset, Mcp-Session-Id, and X-Mcp-Error-Code response
    headers. Credentialed first-party routes such as /api/keys, /api/billing,
    and auth endpoints remain restricted to configured 0xinsider origins.

            requests/minute per user (sliding window), on every authenticated
            route. (2) On the BATCH routes only: 2500 batch item units/minute
            per user, reserved before any item is executed. A batch with N
            requested items costs N item units, including duplicate and invalid
            items. 2500 = 100 requests x 25 items per batch, which is the most
            item work a key can buy through the request limiter at all: a caller
            may spend their entire 100-request minute on full 25-item batches
            without the item budget being what stops them. The REQUEST budget is
            the effective ceiling, and batching is never the more expensive
            choice. The item budget can still deny at a sliding-window boundary
            (both counters carry the previous window forward with a floor, and
            the item counter runs 25x the request counter), so honor a 429 from
            either. Over-quota batches return 429 with Retry-After plus
            RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset before any

            a read that ran and found nothing groupable also leaves the
            directional fields null, and that is honestly "live" -- the
            per-signal nulls already say "nothing to enrich here", so this
            snapshot-level flag carries only what they cannot, namely whether
            the read ran at all. A degraded response is cached on the shorter
            degraded TTL so it self-heals. Reported SEPARATELY from
            ranking_source because the two degradations are independent -- a
            smart-money DB miss weakens the ranking DATA, a directional failure
            removes a ranking WEIGHT -- and a consumer down-weighting a degraded
            response needs to know which input it lost. Omitted on endpoints

                ADDITIVE (#7209). The specific, actionable cause behind `code`,
                when there is one more specific than the code itself. `code`
                keeps its published values, so existing clients are unaffected;
                new clients branch on `reason`. Omitted when the code already
                says everything we know. pick_not_released: no Pick of the Day
                is published for the current product day; schedule one request
                against retry_at instead of polling. unknown_endpoint: the PATH
                is not a route on this API -- read GET /api/v1, do not retry.
                trader_not_tracked: the wallet is real and the URL is right, but
                the trader is outside the HOT/WARM sync tiers -- stop asking for
                this wallet. cursor_expired: pagination went stale mid-walk --
                re-request the first page and continue. read_model_warming: the
                requested endpoint cannot serve its read model yet; exact causes
                are endpoint-specific and can include a cold or contended
                refresh or a dependency that prevented refresh.
                database_unavailable: the API's database or its connection pool
                is temporarily unreachable (a connection-class failure, not a
                query fault); code stays rate_limit_unavailable, nothing is
                rate-limited, retry after Retry-After / retry_at.
                idempotency_in_progress: retain the exact Idempotency-Key and
                request body, then retry shortly. webhook_delivery_in_progress:
                retry the URL or signing-secret configuration change after the
                destination's active request completes.
