Ask in plain words.

Send your ask to one endpoint. The first reply is the exact price. Your x402 client pays it, and the answer comes back in the same call.

Ask Full Auto
curl -i -X POST https://x402.ottoai.services/full-auto \
  -H 'content-type: application/json' \
  -d '{"ask":"Quote the NVDA stock token","price_cap_usd":0.05}'

# The 402 reply carries one exact price (PAYMENT-REQUIRED).
# Your x402 client pays it and sends the same request again.

Without a payment, this call returns the quote and costs nothing.

  1. You ask

    “Quote the NVDA stock token”

  2. Otto quotes one exact price

    $0.013

    $0.003 service + $0.01 fee · USDC on Base

  3. You get the answer

    Stock Token Quote answered, with NVDA read from the ask.

    {
  "matched": true,
  "service": { "name": "Stock Token Quote" },
  "filled": { "token": "NVDA" },
  "data": { … },
  "receipt": {
    "service_usd": 0.003,
    "router_fee_usd": 0.01,
    "charged_usd": 0.013
  }
}

  • One exact price

    The chosen service’s price plus a $0.01 fee, quoted before you pay. Send price_cap_usd and the quote stays within it.

  • A failed answer costs nothing

    If the service cannot answer, you are not charged. Nothing that fits your cap is a free 404, and a price that changed before you paid is a new quote, not a charge.

  • Any x402 client

    Pay with a standard x402 client in USDC on Base. You pay Otto once, and nothing is paid to anyone on your behalf.

  • A receipt with every answer

    Each answer names the service it came from and carries service_usd, router_fee_usd and charged_usd.
