Prism Share Of Voice API

Returns share of voice across two to five brands weighted by engagement, split into web and social, with an emotion breakdown and a per brand trend.

GET /v1/prism/share-of-voice

Last updated October 2026Maintained by the SocialCrawl team

When to use the Prism Share Of Voice API

Use it to compare brands against each other in one call, where brand-mentions covers a single keyword with no competitive split.

Not for one keyword's trend and sentiment (prism/brand-mentions), and it needs two to five brands, so not for a single brand.

From the API reference

Per brand, fans out to content_analysis summary/phrase-trends/sentiment plus /search/everywhere (consuming the real per-platform items_by_source counts, not the capped fused list), then computes a published-formula SOV (web + social, equal-weighted by default), optional true-share-of-category (numeric category_code), and ESOV (market_shares, Binet/Field: a planning signal, not a growth guarantee). The web share is divided from the windowed phrase-trends sum over date_from..date_to, never from the upstream's all-time total_count, which is censored at 4,000,000 and would tie any two brands above that cap at exactly 50/50; the all-time figure still rides along per brand as web_mentions_all_time with a web_mentions_all_time_censored flag. One axis is chosen for the whole table and named in methodology.web_axis, so a brand whose timeline is unavailable can never be compared against a rival's on a different footing; if no brand's timeline is available the table falls back to the all-time totals and _warnings states that your window was not applied, and if those totals are censored it returns no web share at all instead of a fabricated tie. Every measured brand is scored on the SAME evidence basis: if one brand's social leg returns nothing, the whole table drops to the axes every brand has, methodology.basis names it, and _warnings says which brand caused it, so the column is always a real share rather than a mix of formulas. methodology ships the weights, the formula, the axis and the denominators, so you can recompute any share by hand from the same payload. With the social leg on, each brand's highest-engagement social rows (up to methodology.about_brand.max_rows_per_brand) are also judged for whether they are about that brand at all, and a second set of numbers is published next to the first, never in place of it: engagement_sum_about_brand, social_sov_pct_about_brand and sov_pct_about_brand leave out the rows under methodology.about_brand.about_brand_at_or_above, and per_brand[].about_brand lists the excluded row ids, their engagement, and the negative mentions by aspect. The web axis is an index count and is not cleaned. If any brand's rows could not be judged the cleaned numbers are null for the whole table and _warnings says about_brand_unavailable. The price is the same either way. Metered at 40cr/brand (20 web-only); a brand whose social search half-failed is automatically cheaper, with the reason legible in legs[] + per-brand coverage.

Prism API

What can you do with the Share Of Voice API?

The Share Of Voice endpoint gives you structured Prism data with computed fields in a single request. No scraping infrastructure to build or maintain.

Example Request

# GET /v1/prism/share-of-voice: Metered: holds 120 credits per call up front and refunds what the call does not use. Cache hits are free and failed calls are refunded.
# Check the price first for 0 credits: add dry_run=1 to the query. Nothing is fetched or charged.
# --max-time 60: the API's own time limit for this endpoint.
# --retry 3: retries timeouts, 429 and 5xx, honoring Retry-After.
# -o response.json keeps only the final attempt's body.
# One Idempotency-Key per request, reused on every retry, so a retried call is never charged twice.

Parameters

ParameterRequiredDescription
brandsYes2-5 competitor brand names (CSV).
category_codeNoNumeric category-taxonomy code for true-share-of-category (look one up with `GET /v1/content_analysis/categories`).
market_sharesNoJSON map of real market share per brand (fraction or %), e.g. {"notion":0.4,"coda":0.25,"airtable":0.35}, to compute ESOV.
includeNoCSV toggles (default `emotions,social`). Drop `social` for the cheaper web-only variant; drop `emotions` to skip the sentiment leg. The emotion overlay is third-party NLP passed through unmodified and is not scoped to your date window; `methodology.sentiment_provenance` states that on every response that carries it.
page_typeNoOptional surface filter forwarded to the content_analysis legs. (ecommerce | news | blogs | message-boards | organization)
date_fromNoWindow start (YYYY-MM-DD). Defaults to 90 days ago.
date_toNoWindow end (YYYY-MM-DD). Defaults to today.
brand_descriptionsNoOptional JSON map of a one-line description per brand, e.g. {"notion":"the workspace app"}, used to tell a brand apart from its namesakes.

What is the SocialCrawl Share of Voice API?
GET /v1/prism/share-of-voice takes 2-5 brands and returns one ranked share-of-voice table where each brand's share is computed from real per-platform counts (web mention volume plus social engagement) and engagement-weighted with a published formula. No single endpoint computes a competitive share across brands.
How is share of voice calculated?
Each brand gets a web_sov_pct (its mention volume over the total) and a social_sov_pct (its engagement over the total), blended 50/50 by default into sov_pct, which sums to roughly 1.0 across the set. The weights and dead-band are pinned in methodology_version so results are reproducible.
What is ESOV and how do I get it?
ESOV (Excess Share of Voice) is share of voice minus real market share, times 100, the Binet/Field planning signal. Pass market_shares as a JSON map of brand to share and the endpoint computes esov per brand. It is a planning signal, not a growth guarantee.
How much does a share-of-voice call cost?
Pricing is metered at 40 credits per brand for the full web-plus-social report, or 20 credits per brand for the web-only variant when you drop social from include. A brand whose social search half-failed is automatically cheaper, with the reason shown in its per-brand coverage and legs.
Does share-of-voice use the real per-platform counts?
Yes. Social share is computed from items_by_source: the real per-platform counts and engagement from the universal search leg, not from a capped fused list, so the numbers reflect actual platform spread. Emotions come from NLP content analysis, and there is no LLM in the SOV math.
