Be one of the first 20.

You give us:

• An HTTP endpoint we can call (or raw data we host on your behalf)
• A per-call price in USDC, your choice
• A short JSON schema describing the response

We give you:

• Free implementation: x402 wrapping, hosting, sandbox, docs, the whole stack
• USDC settled to your wallet on every paid call — no invoices, no net-30, no reconciliation calls
• A product page at apitoll.io/catalog/<your-service>/ and a sandbox docs page
• Auto-listing on agentic.market the moment the first paid call settles
• Inclusion in /llms.txt, /.well-known/mcp.json, and /.well-known/agent.json
• Direct access to the founders — we personally onboard the first 20.

Settlement is per-call, on-chain, in USDC on Base, into the wallet address you nominate.

• Per-call settlement. Every paid request settles independently to your treasury address. There is no batching, no holding period, no minimum payout, no monthly cycle.
• You hold the wallet. We never custody your USDC. Your treasury is a wallet address you control — provide an existing one, or use a Coinbase Smart Wallet / CDP Server Wallet you create on the spot.
• Transparent fee. Of the per-call price, a defined transaction fee covers facilitator gas, infrastructure, and the platform. The split is documented in your partner agreement and shown on your service detail page.
• Audit trail. Every settlement is an on-chain transaction on Base, viewable on Basescan. We also expose your service-level revenue in the partner dashboard.
• Tax. You are the seller of record for the data. We provide the settlement record; you handle local tax treatment.

The agents that buy your data won't find you by reading marketing copy. They find you by parsing machine-readable signals on your existing site. Drop one of these snippets into your homepage or docs and any browsing agent will discover the paid endpoint:

Pill badge (HTML)

A small inline badge readers can see and agents can crawl. Sits inline with your text or in your header. Replace <your-service> with the slug we assign you.

Preview — renders the same on any partner site:

Larger, more visible. Put it on a dedicated “data” page or sidebar block where you want agents and humans to both notice it.

llms.txt advert (machine-only)

Most browsing agents look at /llms.txt first. Add one line:

# Paid API
- <your-service> data is available per-call in USDC on Base via x402: https://apitoll.io/catalog/<your-service>/

MCP / agent.json reference

If you publish your own /.well-known/agent.json, list us as a paid_data_source:

{
  "paid_data_sources": [
    {
      "provider": "ApiToll",
      "service": "<your-service>",
      "endpoint": "https://apitoll.io/v1/<your-service>/",
      "protocol": "x402",
      "pricing_url": "https://apitoll.io/catalog/<your-service>/"
    }
  ]
}

We'll provide the exact slug + a per-partner snippet on the day your service goes live.
