The daily Perception Index runs from February 2018 with the same formula every day, so each historical value can be recomputed from the stored articles. The public index reports an update frequency of 15 minutes.

REST endpoints for mentions, trends, sentiment, and the Fear & Greed index take a startDate and endDate. Coverage counts were measured on 27 Sep 2026. For the wider data API, see the crypto data API.

Perception is competitive intelligence for crypto marketing, comms, and PR teams. The table below uses each provider's own public site. Where a site does not publish a figure, the cell says Not listed. Checked on 29 September 2026.

On a paid plan, filter matching mentions by sentiment and date. Inspect the source and publication date in each returned record. The feed path is documented as /feed and also accepts /v1/feed.

curl "https://api.perception.to/feed?keyword=bitcoin&sentiment=negative&startDate=2026-03-08&endDate=2026-03-15" \
  -H "Authorization: Bearer pcp_your_key_here"

import requests

headers = {"Authorization": "Bearer pcp_your_key_here"}
params = {
    "keyword": "bitcoin",
    "sentiment": "negative",
    "startDate": "2026-03-08",
    "endDate": "2026-03-15",
}
resp = requests.get("https://api.perception.to/feed", headers=headers, params=params).json()
print(f"Found {len(resp['data'])} articles")

For Claude, ChatGPT, or Cursor, add the Perception MCP server and sign in when the client asks. Cursor reads this from .cursor/mcp.json.

{
  "mcpServers": {
    "perception": {
      "url": "https://mcp.perception.to/mcp"
    }
  }
}

The public index example above shows an aggregate sentiment result. The authenticated feed endpoint returns article-level records. Setup steps for each client are on the MCP page.

Check the source sample, observation window, sentiment definition, and missing-data behavior. Then inspect a returned record and its source.

Confirm the endpoints and usage allowance for the plan your application needs. Use the same company and date range when evaluating providers.

Company dashboards. Put the tone of mentions, volume, and the source list beside the company metrics your team reviews.

Research notebooks. Query historical sentiment by outlet and date range into pandas, and backtest how the tone of mentions led or lagged price at previous cycle turns.

Comms monitoring. Track sentiment on your own company and competitors, broken down by outlet, so you know which stories moved tone and which outlets to brief next.

AI agents. Connect over MCP and let your assistant run the whole loop: search mentions, compare entities, check momentum, and draft the brief. No glue code.
