platform · x api for deal sourcing

the x data that sources deals, without building on the raw x api

the raw x api is expensive, rate-limited, and gives you firehose, not signal. if what you actually want is to source deals from investor behavior on x, frontrun has already done the hard part - the ingestion, the graph, the convergence detection - and hands you a clean api.

can i use the x api to source deals?

you can, but you'd be rebuilding a lot. the raw x (twitter) api gives you tweets and follow lists with heavy rate limits and cost, and none of the hard part: tracking the right 1,000+ investors, detecting when several converge on a young company, and ranking it as signal. frontrun already does that ingestion and turns it into structured pre-round signal, delivered through a simple rest api and an mcp server - so you consume signal instead of building a pipeline.

firehose vs signal

the x api gives you raw follows and posts. sourcing needs the opposite of raw - it needs to know which follows, across which investors, in what window, actually mean a round is coming. frontrun's api returns that answer: converging companies, classified entities, founder and funding context, with dated provenance.

what the frontrun api gives you

a documented rest api at frontrun.vc/v1 with x-api-key auth - track accounts, detect new follows in a time window, surface convergence, classify companies and vcs, and pull funding and founder data. it's the x-derived deal signal, without the x api's cost, rate limits, or ingestion work.

	raw x/twitter api	frontrun api
Gives you	tweets, follows (firehose)	pre-round signal (ranked convergence)
Work required	build ingestion, graph, ranking	call an endpoint
Cost	expensive, rate-limited tiers	$99/mo, generous credits
Agent access	you build it	mcp server included

which is right for you

you were about to build on the x api

don't rebuild the graph - frontrun already ingests and ranks it. consume the signal via one endpoint.

you want data in your own pipeline

the rest api returns structured json for tracking, convergence, founders, and funding - drop it into your stack.

you want your agent to use it

the mcp server wraps the same data as typed tools, no api plumbing required.

frequently asked

is there an x api for deal sourcing?

the raw x api gives firehose data with heavy limits. frontrun is the practical alternative - it turns x follow-graph activity into structured pre-round deal signal via a clean rest api at frontrun.vc/v1, at $99/mo.

how do i get x follow data as structured signal?

use frontrun's api or mcp server. it tracks 1,000+ investors' follow graphs and returns ranked convergence, classified entities, and founder/funding context - the parts the raw api doesn't give you.

how much does the frontrun api cost?

one plan at $99/mo with a 7-day trial, including api + mcp access and 10,000 monthly credits - far below rebuilding on the raw x api.
