is your workload rate limited or volume limited? they want different plans. 200 topics polled hourly is 4,800 calls a day, under 4 a minute. Builder covers it at 100/min, 20,000/day. a 2,000-call backfill wants them at once. 20 minutes at that rate. Scale does it in four.
Published plan limits table: Hobby 4 per minute and 100 per day on market data only, Individual 10 and 2,000, Builder 100 and 20,000 on all endpoints, Scale 500 and 100,000.

hot take: most teams build a history table they did not need. lunarcrush topic spacex the response hands you the daily average next to the current value. 43,000 mentions in the last 24 hours against a 21,000 average. about 2x, no rows stored.
Trimmed CLI output for lunarcrush topic spacex showing mentions_24h of 43,448 beside a daily_average of 21,077.

crypto put up about 521,000 mentions in 24 hours. Bundesliga put up 34,000. Bundesliga's total reach still came out higher. that is an 11x gap per mention, and /categories/list/v1 has a row like it for all 41 categories.
Two category rows from /categories/list/v1: cryptocurrencies with 520,678 mentions and 332.0M engagements at 638 per mention, Bundesliga with 33,944 mentions and 240.4M engagements at 7,082 per mention.

every social data vendor revises history. most do it quietly, and the chart you shipped in Q3 changes shape without telling you. /system/changes logs what can move a historical time series. diff it before debugging your own backfill. who owns that check on your team?
A four step flow: pull a historical series, the vendor revises old rows, diff /system/changes, end with defensible numbers for research and audit.

ask an agent with no live context what is happening with Xbox this week. you get last year, stated with total confidence. lunarcrush.ai serves the same data as markdown at a path, so it reads instead of guessing. /topic/xbox this morning: 94.7M engagements in 24 hours.
A request to lunarcrush.ai/topic/xbox returning markdown showing 94,685,964 engagements in 24 hours and mentions up 12 percent on the week.

Nobody asks you to add a social data platform. They ask you to make the Monday numbers right. Three drop-in points: the MCP server for the assistant your team uses, the CLI in cron for the warehouse load, the REST API for the app. One key covers all three.

Follower count is a weak filter for influence. Rolex, 24h as of this morning. The top-ranked creator has 2,474 followers and 2.61M engagements off 9 posts. Second place has 1.02M followers and 2.34M off 4. creator_rank scores the posts. creator_followers scores the audience.
