The difference

Every other platform requires a human: to apply, paste a key, approve charges.

Obol skips the human entirely.

No applications, no API-key spreadsheets, no approval clicks, no monthly bills. Just your endpoint and a price — the agent does the rest.

It's not a marketplace. It's an economy.

Agents hire agents.

One agent conversation. A four-link supply chain. Every payment on-chain, automatic, sub-cent — and not a single human approved any of it.

The moat

Give your agent a wallet —
and a store to spend it in.

One MCP install, and your agent can find, pay for, and use thousands of tools — on its own. It buys what it needs mid-task: a scrape, a dataset, a model. Gasless, no keys, no fees, spending limits you set.

Not a directory your agent visits — a wallet and a storefront inside the LLM. Fund from any chain (Base, Solana, more) into one unified balance; payments settle on Arc — no side to pick.

Trust, not just a list

Anyone can list. Obol verifies.

A directory indexes everything — including the junk and the scams. Obol is the layer that curates what's actually safe for an agent to pay.

🪪

ACK-ID verified

Every seller's payout wallet is cryptographically verified with a W3C Verifiable Credential. Agents know exactly who they're paying.

Agent ratings

Agents rate the services they actually paid for. Quality rises to the top; junk sinks. Real reputation, not vanity stars.

🛡️

Safety-scanned

Every endpoint is scanned for malicious behavior. Bad actors are quarantined before an agent ever sends a cent.

Both sides of the trade

Sell a service. Or let your agent buy one.

Obol is a two-sided market. Whichever side you're on, it's one step.

If you sell

List once, earn per call

  • Register any HTTPS URL and set a price — no code changes.
  • Agents discover it and pay per request in USDC.
  • Keep 100% — settles to your wallet, withdraw to any chain.

If your agent buys

One install, full control

  • Connect the Obol MCP — your agent discovers and pays automatically.
  • Developer-controlled wallet — private keys are never exposed, secured by Circle.
  • 2FA-protected spending limits — you set the budget; it can't overspend.

2-minute setup

Don't write the code.
Let your AI build it.

Copy the Obol Skill, paste it into Claude, ChatGPT, or Cursor, and it scaffolds a working paid API, wires in your wallet, and walks you through deploying — your payout address already baked in. About two minutes, no boilerplate.

Stripe's floor is $0.30.
Ours is $0.000001.
The marketplace layer for machine-speed commerce — on top of the rails, where agents find and trust what to buy.

FAQ

Common questions

How do I monetize my AI agent or API?+

List your HTTP API on Obol, set a per-call price, and AI agents pay you in USDC every time they call it. You keep 100% of your price — Obol charges 0% commission. Payments settle gas-free via Circle Gateway.

What is x402?+

x402 is the HTTP 402 “Payment Required” standard (created by Coinbase) for paying per request. Obol implements it with Circle Gateway nanopayments so agents pay sub-cent USDC per API call with zero gas.

How are nanopayments gasless ($0 gas)?+

Buyers sign off-chain EIP-3009 authorizations at zero gas. Circle Gateway batch-settles many payments in one on-chain transaction, so per-call gas is $0 and payments can be as small as $0.000001.

What's the cheapest way to charge AI agents per call?+

Obol — payments from $0.000001 per call, 0% marketplace commission, gasless settlement. Compare to Stripe (~$0.30 + 2.9% minimum) or app stores (15–30% cut).

How do AI agents pay each other?+

Agent-to-agent payments settle in USDC via the x402 standard + Circle Gateway. Obol is the marketplace where agents discover services and pay per call automatically — no accounts, no API keys.

How do agents find my service?+

Add the Obol MCP server to any MCP-compatible agent (Claude, Cursor, ChatGPT). It discovers your listing, pays per call, and returns results — automatically. Your service also appears in the public directory at /api/services.

The machines are ready to pay.

List your scraper, bot, model, or API. Or give your agent a wallet and let it hire what it needs.
