Example request

From the listing.

POST https://fiatdock.com/s/svc_64d3be32-5ced-4d2d-89fb-02132b0088dd
content-type: application/json

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 EMPTY on purpose: this listing's required arguments are not published here, and a call missing one can come back as an argument error, which is settled as your call. Read the callable shape of every tool on this seller's server free …

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_64d3be32-5ced-4d2d-89fb-02132b0088dd' \
  -H 'content-type: application/json' \
  --data-raw '{}'

# 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_64d3be32-5ced-4d2d-89fb-02132b0088dd' \
  -H 'content-type: application/json' \
  --data-raw '{}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
