Your agent finds emails.
You pay per call.

Email intelligence API paywalled per-request with x402. No account, no subscription, no keys to rotate. Show up with USDC and get data.

$ curl -i "https://fov.brij.fi/email-finder?domain=stripe.com&first_name=Patrick&last_name=Collison"

# HTTP 402
# Payment-Required: <base64 requirements>

# Sign the USDC transaction per the x402 spec,
# then retry with the signature header:

$ curl -i -H "PAYMENT-SIGNATURE: <sig>" "https://fov.brij.fi/email-finder?domain=stripe.com&first_name=Patrick&last_name=Collison"

# HTTP 200
# Payment-Response: <settled>
# {"email": "[email protected]", "score": 97, ...}
from x402 import X402Client

client = X402Client(solana_wallet)

data = client.get(
  "https://fov.brij.fi/email-finder",
  params={
    "domain": "stripe.com",
    "first_name": "Patrick",
    "last_name": "Collison",
  },
)

# data == {"email": "[email protected]", "score": 97, ...}
# The client handles 402 + signing + retry transparently.

Why FOV

Email APIs built for autonomous agents.

Traditional email intelligence APIs require accounts, subscriptions, and credential plumbing that agents weren't designed to handle. FOV uses the x402 payment flow your agent already knows.

Traditional approach

  • 1
    Sign up for a provider
    Email, verification, credit card, pick a monthly plan.
  • 2
    Manage API keys
    Store secrets, inject at runtime, rotate when compromised.
  • 3
    Monthly subscription
    Pay whether your agent runs once a month or ten thousand times.
  • 4
    Monitor quota & billing
    Rate limit errors, overage alerts, forced plan upgrades.

With FOV

  • No account needed
    Payment is authentication. Show up with USDC and get data.
  • Pay per call in USDC
    Fractions of a cent settle on-chain per request, nothing more.
  • x402-native
    Same HTTP 402 flow your agent already handles for every other paid API.
  • Marketplace-discoverable
    Indexed by x402scan and Bazaar so agents find FOV without configuration.

Discovery

Agent-ready out of the box.

FOV publishes standard discovery documents so any x402-compatible agent, marketplace, or orchestrator can find and use it automatically.

Email intelligence that costs
what it's worth.

Hand your agent $0.05 per lookup. No setup, no subscription, no keys to rotate.
