The view-velocity ladders every YouTube benchmark is read against: GET /insights/youtube/view-velocity-bands

What this endpoint answers

The three subscriber bands a channel's views per day is ranked inside, each with its percentile ladder, how many channels stand behind it, what share of those carry a usable series, and when it was last rebuilt. Published so a percentile is never a number with an invisible population behind it.

This is a catalog read: it is served from the CRM Solid database in milliseconds, costs one budget unit, and reports how old the reading is in meta.cache_age_s. It needs the insights:read scope (Insights): Engagement rates, top posts, viral patterns, cohort benchmarks.

Good to know

measured is the ladder's real n and channels is the whole band. Both are returned because coverage is the thing a caller has to decide whether to trust, and an inner join would have reported 100% coverage of the channels that happen to be covered.
quantiles is 101 points, p0 through p100, in views per day. The example truncates it to the first four, which really are zero or close to it: 2.4% to 3.2% of the channels in each band added no views at all across the 14 days to 2026-08-31, and a channel that stopped is still a channel in the band.
There is no band below one million subscribers. Coverage collapses there: 261 of 10,421 channels between 300k and 1M had 14 or more observed days in the 30 to 2026-08-31, and zero of the 19,779 channels below 100k had any. GET /insights/youtube/{handle}/benchmark answers below_coverage_floor rather than ranking against a fifth of a band.
An empty bands array is a defined state rather than an error: it means the daily rollup has not written anything in this environment, and every benchmark will answer band_not_built until it has.
The window is 14 days. Every channel placed against these ladders is measured over the same 14 days with the same minimum of five observed days, so the comparison is like for like.

Parameters

This endpoint takes no path or query parameters.

Call it

Authenticate with a bearer token or the x-api-key header. Keys are server-to-server credentials. Never embed one in front-end code - call the API from your own backend and forward the result.

curl

curl "https://crmsolid.com/data-api/v2/insights/youtube/view-velocity-bands" \
  -H "Authorization: Bearer psk_live_..."

JavaScript

const res = await fetch("https://crmsolid.com/data-api/v2/insights/youtube/view-velocity-bands", {
  headers: {
    Authorization: `Bearer ${process.env.CRM_SOLID_DATA_API_KEY}`,
  },
});

if (!res.ok) {
  const { error } = await res.json();
  throw new Error(`${error.code}: ${error.message} (${error.request_id})`);
}

const { data, meta } = await res.json();

Python

import os

import requests

res = requests.get(
    "https://crmsolid.com/data-api/v2/insights/youtube/view-velocity-bands",
    headers={"Authorization": f"Bearer {os.environ['CRM_SOLID_DATA_API_KEY']}"},
    timeout=30,
)
res.raise_for_status()

payload = res.json()
data, meta = payload["data"], payload["meta"]

Keys look like psk_live_... for production keys, psk_test_... for test keys and are minted in the panel.

What comes back

Success is { data, meta }. Failure is { error: { code, message, request_id } }. The body below is the spec's own example: the values in it are illustrative readings, not live numbers.

When it fails

GET /insights/youtube/view-velocity-bands documents 7 failure statuses. Branch on error.code, which is stable and enumerated; message is prose and may change.

401Unauthorizedunauthorized | invalid_key
No key was presented, or the key is unknown, revoked or expired.
402PaymentRequiredpayment_required | subscription_inactive
The key is valid but the plan behind it cannot serve the call: the included requests are spent and overage is switched off, capped or unfunded (payment_required), or the billing period lapsed and was not renewed (subscription_inactive). Retrying does not help; paying does. The X-Plan-* headers on this response say how far past the line you are.
Carries X-Plan, X-Plan-Limit, X-Plan-Overage, X-Plan-Period-End, X-Plan-Remaining.
403Forbiddenforbidden_scope | forbidden_ip
The key is valid but not allowed to make this call: it lacks the scope, or the request came from an address outside the key's allowlist.
422InvalidRequestinvalid_request
A parameter is malformed, out of range or mutually exclusive with another. `details` names the offending fields.
429RateLimitedrate_limited | quota_exceeded
Either the burst ceiling for the current minute or the daily quota is spent. Distinguish with the code: rate_limited clears within the minute, quota_exceeded does not clear until 00:00 UTC.
Carries Retry-After, X-Quota-Limit, X-Quota-Remaining, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, X-Request-Id.
500InternalErrorinternal_error
Something failed on our side. Internals are never leaked; quote the request id.
503Unavailableupstream_timeout | upstream_error | not_configured
The request could not be served right now. BRANCH ON error.code, not on the status: 'upstream_timeout' means a source was too slow (this is what a catalog query hitting its 15-second statement timeout returns, so it is reachable from any endpoint that reads the corpus, not only the live-scrape ones) and the same call is worth retrying with backoff - narrowing it with a smaller limit, a filtered scope or a less popular account makes it far less likely; 'upstream_error' means a source was unreachable, so back off further; 'not_configured' means the capability has no backing service in this deployment, and retrying will never help.

Every response carries X-Request-Id and meta.request_id. Quote it in support requests.

Coverage and limits

This endpoint covers YouTube. Rate limits come from the tier on your key.

YouTube

Tier	Requests a minute	Requests a day	Live reads a minute
free	30	1,000	5
standard	120	25,000	20
pro	600	250,000	60
unlimited	6,000	10,000,000	600

This call only draws on the ordinary per-minute and per-day columns. Every response reports where you stand in X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset and the X-Plan headers.
