Metadata

name: signet
description: Interact with Signet onchain advertising on Hunt Town. Use when the user wants to check spotlight ad prices, list current ads/signatures, or post a URL to the Signet spotlight. Supports x402 payment protocol for programmatic ad placement by AI agents.

Signet

Signet is an onchain advertising protocol on Base (Hunt Town Co-op). URLs compete for the spotlight slot, backed by HUNT tokens.

CLI Tool

Install and use the @signet-base/cli tool:

# Estimate cost for spotlight placement
npx @signet-base/cli estimate --hours 6

# List recent signatures
npx @signet-base/cli list --count 10

# Post a URL (simulate first to check cost)
npx @signet-base/cli post --url https://example.com --hours 6 --simulate

# Post for real (requires PRIVATE_KEY env or --private-key)
PRIVATE_KEY=0x... npx @signet-base/cli post --url https://example.com --hours 6

Commands

estimate — Get estimated USDC cost. Options: --hours <0-24>, --simulate
list — List recent spotlight signatures. Options: --count <n>
post — Place a URL on the spotlight via x402 payment. Options: --url <url>, --hours <0-24>, --private-key <key>, --simulate

The --simulate flag on post runs the full x402 flow (estimate, get 402 requirements, create payment) but stops before submitting. Use it to verify costs before committing.

API (Direct HTTP)

Base URL: https://signet.sebayaki.com

Estimate Cost

curl "https://signet.sebayaki.com/api/x402/estimate?guaranteeHours=0"

Response:

{
  "guaranteeHours": 0,
  "estimatedUSDC": "12.28",
  "estimatedUSDCRaw": "12280000",
  "spotlightAvailable": true,
  "spotlightRemainingSeconds": 0
}

guaranteeHours (0-24): hours the spotlight is guaranteed. 0 = can be overtaken immediately.

List Signatures

curl "https://signet.sebayaki.com/api/signature/list?startIndex=0&endIndex=5"

Returns { signatures: [{ signatureIndex, url, huntAmount, viewCount, clickCount, metadata, timestamp, userWallet }] }.

Post Spotlight (x402)

# Step 1: POST without payment → 402 with requirements
curl -X POST https://signet.sebayaki.com/api/x402/spotlight \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com","guaranteeHours":0}'

# Step 2: POST with payment header → 200
curl -X POST https://signet.sebayaki.com/api/x402/spotlight \
  -H "Content-Type: application/json" \
  -H "X-402: <encoded-payment>" \
  -d '{"url":"https://example.com","guaranteeHours":0}'

The x402 payment flow:

Server returns 402 with accepts array (USDC amount, payTo address, network)
Client signs a USDC payment (Permit2 on Base) using @x402/core and @x402/evm
Client retries with payment header
Server verifies via facilitator, executes onchain tx, settles payment
