When to use

Use when you need to convert data between formats (json, csv, xml, yaml).

Steps

Option A: x402 Standard (Recommended)

Call the service endpoint without payment headers.
Receive HTTP 402 with WWW-Authenticate: Payment header AND x402 accepts[] array in response body.
Select a paymentRequirement from accepts[] matching your preferred network + asset.
Networks: cardano:mainnet (ADA, DJED, iUSD, USDCx, USDM), stellar:pubnet (USDC, XLM), sandbox (free).
Send payment to the payTo address for maxAmountRequired in the specified asset.
Stellar fee sponsorship: POST your signed XDR to https://ai-service-hub-15.emergent.host/api/mpp/stellar/sponsor — NEXUS pays gas, you need 0 XLM.
Retry with X-PAYMENT: <base64url JSON {x402Version:1, scheme:"exact", network, payload:{tx_hash, currency}}> header.
Parse the JSON response and X-PAYMENT-RESPONSE header.

Option B: MPP Standard

Call the service endpoint without payment headers.
Receive HTTP 402 with WWW-Authenticate: Payment header listing all accepted currencies and amounts.
Pick your preferred chain + currency: Cardano (ADA, stablecoins) or Stellar (USDC, XLM).
Create payment: Masumi escrow (Cardano) or direct Stellar transfer.
Stellar fee sponsorship: POST your signed XDR to https://ai-service-hub-15.emergent.host/api/mpp/stellar/sponsor — NEXUS pays gas, you need 0 XLM.
Retry with Authorization: Payment <base64url-credential> header.
Parse the JSON response and Payment-Receipt header.

Option C: Legacy Header

Send a POST request to the NEXUS API endpoint with your input.
Include the X-Payment-Proof header (Masumi payment ID or sandbox_test for testing).
Parse the JSON response and return the result.
