Common questions.

If something isn’t here, the docs probably have it — or reach out and we’ll add it.

What is Particle?
Particle is a B2B data platform that exposes real-time company and podcast intelligence as a single API for developers, brands, and AI agents.
What APIs does Particle offer?
Particle offers two API surfaces: Company Intelligence (profiles, earnings, SEC filings, and reference data for public companies) and Podcast Intelligence (transcription, speaker diarization, and semantic search across thousands of podcasts).
Who uses Particle?
Developers building agentic and analytical products, brands and advertisers measuring earned media and podcast mentions, and research teams sourcing alternative data signals.
How do I get started?
Sign up at platform.particle.pro/register — you'll get a free $10 starter credit (about 1,000 requests). Create an API key and you're set to call the REST API directly, or wire up the MCP server for your agent in one command.
How can I access the data?
Four ways. The REST API with an API key, for scripts, backends, and productization. The MCP server at `https://mcp.particle.pro`, for Claude, Cursor, Codex, and any MCP client. For enterprises, a real-time episode firehose and bulk data snapshots. And pay-per-request over x402 or MPP — call any billable endpoint or MCP tool with no account and no key by paying in USDC on Base.
What gets indexed?
150,000+ podcasts and counting, including the entire Apple Podcasts Top 200 (US) across 130+ English-language verticals plus the long tail of independent shows our customers track. Each show is ingested continuously — new episodes are typically transcribed and enriched within minutes of publication.
How can I search?
Three modes share the same endpoint: an exact keyword or phrase, a semantic match (natural language), or a canonical entity (filter by a person, company, or topic). Each result is a speaker-labeled transcript window with timestamps. Full reference at docs.particle.pro/podcasts/search.
Are transcripts diarized and speaker-identified?
Yes. Every transcript ships with full speaker diarization, and voices are resolved to real people — host, guest, advertiser, correspondent — with role labels and a link to the canonical entity record. Word-level timestamps and resolved entity mentions live on their own endpoints (`/transcript/words` and `/transcript/mentions`) alongside the main transcript.
Can I get audio clips, not just transcripts?
Yes. Each episode's full audio is available, and we also segment every episode into topical clips with their own audio file, transcript window, and engagement scoring. You can carve a custom slice by start/end seconds for any episode, and embed it on a third-party page via Particle's clip widget.
What transcript formats are available?
Three formats from the same transcript endpoint via a `format` parameter: `dialogue` (speaker-attributed lines with timestamps — the default), `text` (plain text), and `srt` (SubRip subtitles). Word-level transcripts live at `/transcript/words` for use cases that need per-token timing.
How quickly are new episodes available?
Most episodes are fully transcribed, diarized, and enriched within minutes of publication. The status of the ingestion pipeline is published at status.particle.pro.
Can I use Particle with my AI agent — Claude, Cursor, Codex?
Yes. Particle ships an MCP server at `https://mcp.particle.pro` that any MCP-compatible client can connect to. Install commands for Claude Code, Claude Desktop, Cursor, and VS Code are at docs.particle.pro/mcp/overview. Agents that hold a wallet and no key can pay per tool call with x402 or MPP instead.
Can I track a specific entity or guest?
Yes. Alerts watch every indexed podcast for a canonical entity — a person, company, brand, or topic — or for a guest appearance, and notify you as-it-happens or in a daily or weekly digest, each match with the clip, transcript, and metadata attached. Delivery is by email, Slack, or webhook. Alerts are entity-based rather than free-text keyword matches, so mentions resolve to the same record wherever they appear.
How does pricing work?
Every plan starts with a $10 free credit (about 1,000 requests). After that, Individual is $29/month for 10,000 requests and Business is $399/month for 100,000, with overages billed per request at list prices (half off on Business). Enterprise tiers and custom contracts are available too — see the pricing page or contact us.
Can I integrate the data into my product?
Yes — the REST API is built for productization. Pull episodes, clips, transcripts, entities, and rankings directly into your platform. Full reference and rate-limit guidance at docs.particle.pro; read the API Terms of Service for the full rules and restrictions.
