NEXUS Meeting Notes

Convert meeting transcripts into structured notes

Security Scan

The skill is internally consistent: it is an instruction-only connector that sends meeting transcripts to a paid NEXUS service and requires a single payment-proof credential; nothing requested or described deviates from that purpose.

Purpose & Capability

Name/description (convert transcripts to notes) align with the runtime instructions and required network access. Requesting a payment proof credential for a paid API is coherent with the stated purpose.

Instruction Scope

SKILL.md is an instruction-only API client: it tells the agent to POST inputs to a single external endpoint and to include payment headers. It explicitly disallows filesystem and shell access. The doc also describes optional flows that involve posting a user-signed Stellar XDR to a sponsor endpoint — this requires the user/agent to produce a signed transaction outside the skill and would expose that signed payload to the external service. This is expected for the described payment flows but is worth noting as sensitive.

Install Mechanism

No install spec or code is included (instruction-only). Nothing is downloaded or written to disk by the skill itself.

Credentials

The skill only requires one environment variable, NEXUS_PAYMENT_PROOF, which is the declared primary credential and matches the documented payment header usage. This is proportionate for a paid API; however, NEXUS_PAYMENT_PROOF is a sensitive value and will be transmitted to the external service when the skill is invoked.

Persistence & Privilege

always is false and the skill does not request elevated or persistent platform privileges. It does permit network access as required to call the external API.

Assessment

This skill sends your meeting text and a payment-proof credential to an external host (https://ai-service-hub-15.emergent.host). Only install it if you trust that service. For testing use the documented sandbox value (X-Payment-Proof: sandbox_test). Do not store unrelated secrets as NEXUS_PAYMENT_PROOF; treat that env var as sensitive because it will be transmitted to the provider. If you need stronger assurance, review the provider's documentation and privacy terms on their site before enabling the skill.

When to use

Use when you need to convert meeting transcripts into structured notes.

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.

External Endpoints

URL	Method	Data Sent
https://ai-service-hub-15.emergent.host/api/original-services/meeting-notes	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.
