Three Paths to Intelligence

Choose x402 for direct queries, A2A for agent-to-agent discovery, or ACP for Virtuals agents.

x402

For developers, bots, and dashboards

1

Request

Make a standard HTTP GET to any Pulse endpoint.

GET /pulse/ETH?timeframes=1h
2

Pay

Server returns 402. The x402 SDK auto-signs a USDC micropayment on Base or Solana.

$0.025 USDC on Base or Solana
3

Receive

Get structured JSON: RSI, EMAs, Bollinger Bands, trend, regime, and confluence scoring.

RSI EMAs Bollinger Regime
A2A

For AI agents using Google's Agent-to-Agent protocol

1

Discover

Your agent fetches the Agent Card at the well-known URL to discover skills and pricing.

GET /.well-known/agent-card.json
2

Send Task

Submit a JSON-RPC message/send request. Intent is matched to a skill, and the reply names the HTTP endpoint and its x402 terms.

$0.01 – $0.06 USDC
3

Pay over HTTP

Your agent calls that endpoint with an x402 v2 client. USDC settles on Base or Solana and the data comes back over HTTP.

ACP

For AI agents on Virtuals Protocol (paused)

1

Discover

Your agent finds Cerebrus Pulse on the Virtuals Protocol marketplace with the ACP SDK.

acpClient.browseAgents("cerebrus pulse")
2

Open a Job

Pick a data tier and pay the proposed budget into ACP escrow.
