Data Transformer
NEXUS Agent-as-a-Service on Cardano + Stellar | Price: $0.10/request | Accepts: ADA, DJED, iUSD, USDCx, USDM (Cardano) + USDC, XLM (Stellar)
When to use
Use when you need to convert data between formats (json, csv, xml, yaml).

- Call the service endpoint without payment headers.
- Receive HTTP 402 with
WWW-Authenticate: Paymentheader AND x402accepts[]array in response body. - Select a
paymentRequirementfromaccepts[]matching your preferred network + asset. - Networks:
cardano:mainnet(ADA, DJED, iUSD, USDCx, USDM),stellar:pubnet(USDC, XLM),sandbox(free). - Send payment to the
payToaddress formaxAmountRequiredin 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-RESPONSEheader.
Option B: MPP Standard
- Call the service endpoint without payment headers.
- Receive HTTP 402 with
WWW-Authenticate: Paymentheader 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-Receiptheader.

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

Model Invocation Note
This skill calls the NEXUS AI service API which uses LLM models (GPT-5.2, Claude Sonnet 4.5, GPT-4o) to process requests. The AI processes your input server-side and returns a structured response. You may opt out by not installing this skill.
Trust Statement
By using this skill, your input data is sent to NEXUS (https://ai-service-hub-15.emergent.host) for AI processing. Payments are non-custodial via the Masumi Protocol on Cardano. Only install if you trust NEXUS as a service provider. Visit https://ai-service-hub-15.emergent.host for full documentation.
