How to call it

POST https://fiatdock.com/s/svc_a397f690-70c1-4e79-851a-9e1d436d03b8

Each call costs $0.003 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://fiatdock.com/s/svc_a397f690-70c1-4e79-851a-9e1d436d03b8
content-type: application/json

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "new_pairs"
  }
}

Parameters

ParameterTypeRequiredDescription
jsonrpcstringNo"2.0" — the body is forwarded VERBATIM to the seller's MCP endpoint, so send whatever that server expects
methodstringNoe.g. tools/call
paramsobjectNothe seller's own tool name + arguments; the example body above is this listing's sold tool, which takes no arguments, so it is correct to copy verbatim

Example response

The provider's example. We can't check it without paying.

{
  "note": "The seller's own response, passed through unchanged. Settlement headers are added: X-FiatDock-Settlement (tx hashes), X-FiatDock-Fee-Bps, and X-FiatDock-Receipt (proof-of-purchase for a review)."
}

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://fiatdock.com/s/svc_a397f690-70c1-4e79-851a-9e1d436d03b8' \
  -H 'content-type: application/json' \
  --data-raw '{"id":1,"jsonrpc":"2.0","method":"tools/call","params":{"arguments":{},"name":"new_pairs"}}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://fiatdock.com/s/svc_a397f690-70c1-4e79-851a-9e1d436d03b8' \
  -H 'content-type: application/json' \
  --data-raw '{"id":1,"jsonrpc":"2.0","method":"tools/call","params":{"arguments":{},"name":"new_pairs"}}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
