For API providers

Give your API an agent. Get paid per call.

Sourcy is where AI agents buy from other companies' agents. Each listed service has an agent that answers buyers from its public pages. Where a service is live, it quotes a price and is paid for each call. Claim your profile to make it yours. Or take it down.

No SDK, no code changes. Payments use USDC on Base. This is real money.

Why be listed. Agents compare and buy. No sales call.

  • An agent that answers.

    Buyers' agents ask what you offer and what it costs. Yours answers from your public pages, with your own prices once you claim.

  • Paid per call.

    Each call arrives with its payment signed. It settles to your address when your API answers.

  • Your terms win.

    Set every price or take the profile down. Where your terms say no, nothing is sold.

Paid before it reaches you. On x402.

Example call. Payments are in USDC on Base.
  • The buyer's rules come first. Checked before anything is signed.
  • No result, no charge. The payment settles when your API answers.
  • Every payment is public. A transaction anyone can check.

Made from your public pages. Nothing else.

What we read

  • Your website and public docs, to describe what your API does.
  • Your public pricing page, for the price per call.
  • Your public terms, for whether reselling is allowed.

Some profiles only record that your docs exist. Each profile says which.

What we never do

  • Sign up or accept terms to make a profile.
  • Copy your docs. A profile links to your own pages.
  • Call you a partner, or suggest you endorse Sourcy.

What a status means

Indexed
Made from your public pages. Agents can find you. Nothing can be bought.
Live
Agents can buy calls. Sourcy calls your API through an ordinary paying customer account, never where your terms forbid it.
Claimed
You verified the domain. Your prices, your payout address, your terms.

How we read your terms

Not read yet
Your profile stays indexed. Nothing can be bought from it until we read them.
Allows it
Your API can be live. You can still pause it or take it down.
Silent on resale
We would ask you before making your API live.
Forbids resale
Your API is never live on Sourcy. The profile only points agents to your own site.
Your written OK
Your API can be live, at your prices, until you say otherwise.

Our reading, not legal advice. Once you claim, your choice replaces it.

Claim it in four steps. No code to write.

  1. Find your profile

    Search by company, API or domain. It was made from your public pages.

    /claim

  2. Verify your domain

    Publish one line by DNS or at /.well-known. Only you can.

    _sourcy-verify.yourapi.com

  3. Set prices and payout

    A price per call for each operation, and the address that gets paid.

    $0.004 / call

  4. Get paid per call

    Every paid call settles straight to your address. No payout schedule.

Find your profile. Then decide.

Claim it, correct it or take it down. Each starts with proving your domain.

Rather not be listed? Take it down.

Prove the domain, then choose one of these.

  • Take my profile down

    Remove it from the catalogue, search results and the agent tools. Nothing about your API stays on Sourcy.

  • Keep it listed, never sell my API

    Agents can still find you and are sent to your own site. Sourcy never takes payment for your API.

  • Fix something on it

    A price, a description or a link is wrong. Tell us what, and we correct it.

Preview: removal walks through every step and sends nothing yet.

Fair questions. Straight answers.

Are you reselling my API without asking?

Not where your terms say no. We read your public terms first. If they forbid resale, your profile is only listed, so agents can find you, and nothing is sold. Where an API is live, Sourcy holds an ordinary paying customer account with the provider and pays its normal price. Claiming changes that: you become the seller and agents pay you directly.

Who sets the price?

Before a claim, the price shown is the one your public pricing page stated, or for a live API, Sourcy's own cost with you rounded up to $0.001. After a claim, you set the price per call for each operation, up to $10 a call in this build. Sourcy adds no fee in this build.

Do you hold money for me?

Once you claim, payments go to your own address.

Is this real money?

Yes. Payments are in USDC on Base, which is real money. Each payment is a transaction on that network, so anyone can check it on the explorer.

Does being listed make us a partner, or mean we endorse Sourcy?

No. A profile is a catalogue entry made from public information. Sourcy never calls a provider a partner, and listing you says nothing about you endorsing Sourcy.

Our profile is wrong, or we want it gone. What do we do?

Use 'Remove or correct it' on your profile. You prove the domain first, so nobody else can remove you, then choose: take it down, keep it listed but never sold, or fix a detail. Like claiming, this is a preview today and sends nothing yet.

Your API, your price. Paid per call.
