NEXUS Translate

High-quality translations with cultural awareness (50+ languages)

Security Scan

The skill's requirements and runtime instructions are internally consistent with a paywalled translation API, but it sends all input to an external host and requires a payment-proof secret — so only install if you trust that service and follow the precautions below.

Purpose & Capability

Name/description (translation) align with the SKILL.md: the skill purely documents calling an external translation API and payment flows. The single required env var (NEXUS_PAYMENT_PROOF) maps to the documented X-Payment-Proof/Authorization header and is coherent with a paid service.

Instruction Scope

Instructions tell the agent to POST input to https://ai-service-hub-15.emergent.host and to include payment headers/credentials. They do not instruct reading unrelated files or system paths. Note: the skill asks users to POST signed Stellar XDRs to a sponsorship endpoint — this requires caution but does not itself ask the agent to access private keys (it expects a pre-signed XDR).

Install Mechanism

Instruction-only; no install spec and no code is written to disk. This minimizes installation risk.

Credentials

Only a single env var (NEXUS_PAYMENT_PROOF) is required, which is proportionate for a paywalled API. However the variable is a secret-like artifact: if it represents a live payment credential, exposing it to the agent (or storing it in shared environment) could enable charges. The SKILL.md shows it being sent verbatim in request headers.

Persistence & Privilege

always is false and the skill has no install/persistence behavior. It does request network access in its instructions (expected for an external API). Autonomous invocation is allowed by default on the platform — not a problem here but note it could trigger network calls that consume the provided payment proof.

Assessment

This skill is coherent: it simply wraps a paywalled translation API and requires a payment-proof value (NEXUS_PAYMENT_PROOF) which it sends to https://ai-service-hub-15.emergent.host. Before installing: 1) Verify and trust the external host (ai-service-hub-15.emergent.host) and the platform’s docs; there is no homepage provided in the package, so confirm the service independently. 2) Treat NEXUS_PAYMENT_PROOF as sensitive — use a sandbox/test token (the docs mention sandbox_test) for evaluation and avoid placing real payment credentials in shared agent env. 3) Consider the data you will send: all input is transmitted to the external service over HTTPS, so avoid sending PII or secrets. 4) If you will use the Stellar sponsorship flow, only POST signed XDRs you created with your own wallet; do not expose private keys to the agent. 5) Monitor usage and billing (price noted: $0.12/request) and restrict agent triggers if you are concerned about automated/unsupervised invocations consuming credits. 6) The README tags include unrelated terms (e.g., health-monitoring) — likely harmless but worth noting as sloppy metadata. If you need stronger assurance, ask the publisher for verifiable documentation or a canonical homepage and test with sandbox_test before providing any real payment proof.

When to use

Use when you need to translate text between languages.

Steps

Option A: x402 Standard (Recommended)

1. Call the service endpoint without payment headers.
2. Receive HTTP 402 with WWW-Authenticate: Payment header AND x402 accepts[] array in response body.
3. Select a paymentRequirement from accepts[] matching your preferred network + asset.
4. Networks: cardano:mainnet (ADA, DJED, iUSD, USDCx, USDM), stellar:pubnet (USDC, XLM), sandbox (free).
5. Send payment to the payTo address for maxAmountRequired in the specified asset.
6. 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.
7. Retry with X-PAYMENT: <base64url JSON {x402Version:1, scheme:"exact", network, payload:{tx_hash, currency}}> header.
8. Parse the JSON response and X-PAYMENT-RESPONSE header.

Option B: MPP Standard

1. Call the service endpoint without payment headers.
2. Receive HTTP 402 with WWW-Authenticate: Payment header listing all accepted currencies and amounts.
3. Pick your preferred chain + currency: Cardano (ADA, stablecoins) or Stellar (USDC, XLM).
4. Create payment: Masumi escrow (Cardano) or direct Stellar transfer.
5. 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.
6. Retry with Authorization: Payment <base64url-credential> header.
7. Parse the JSON response and Payment-Receipt header.

Option C: Legacy Header

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

API Call

curl -X POST https://ai-service-hub-15.emergent.host/api/original-services/translate \

External Endpoints

URL	Method	Data Sent
https://ai-service-hub-15.emergent.host/api/original-services/translate	POST	Input parameters as JSON body

Security & Privacy

• All data is sent to https://ai-service-hub-15.emergent.host over HTTPS/TLS.
• No data is stored permanently; requests are processed and discarded.
• Payment proofs are verified on the Cardano blockchain via the Masumi Protocol.
• No filesystem access or shell execution required.

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.
