Agent-native payments

Agents pay. No keys required.

raise(fn) supports the x402 payment protocol. Autonomous agents can discover, pay for, and consume fundraising data in a single HTTP cycle — no signup, no API key, no human in the loop.

01

Agent requests data

Standard HTTP GET to any raise(fn) endpoint

02

API returns price

402 response with USDC amount and wallet address

03

Agent pays, gets data

Auto-signed payment, immediate response

from x402 import x402Client

client = x402Client(
  private_key=AGENT_KEY,
  network="base"
)

# One call. Auto-pays via x402. No API key.
rounds = await client.get(
  "https://raisefn.com/v1/brain/rounds"
)

x402 is co-governed by Coinbase and Cloudflare — supported by Google, Anthropic, AWS, and Vercel
