POST /v1/carbon · ICAO CEC v13.1 · GHG Protocol Scope 3 Category 6

    Compliance-grade flight emissions. One call.

    ICAO CEC v13.1 CO₂ per passenger — the methodology recommended by GHG Protocol for Scope 3 Category 6 business travel reporting. Cabin comparison, EU ETS offset pricing, and route map in a single POST. MCP-ready for AI agents.

    One API call instead of four separate vendors. Used by travel apps, ESG platforms, and enterprise reporting pipelines alike.

    The problem

    Aviation data is still an integration nightmare

    To turn a single flight into a complete user experience, developers have had to license, implement, and keep four separate third-party APIs in sync.

    Separate CO₂ API

    A different vendor, different auth, different data model — no methodology transparency, no standard compliance guarantee.

    Separate logo API

    Airline logos from yet another provider, manual IATA code matching, inconsistent image formats and update cycles.

    Separate map API

    Route maps as a third service, with its own pricing model, rate limits, and SLA to manage.

    No AI integration

    No language model can query real-time CO₂ data directly — you write middleware you never wanted to maintain.

    The solution

    Everything you need. One API call.

    ICAO-certified CO₂ calculation, cabin comparison, EU ETS offset pricing, and route map — bundled into a single POST request.

    ICAO CEC v13.1 Calculation Engine

    Real aircraft performance data from the ICAO database, correct load factor, and Y-seat allocation across all four cabin classes. GHG Protocol Scope 3 compliant — the same standard airlines use for CORSIA and EU ETS reporting.

    Native AI Integration

    MCP Server for Claude, GPT, and other LLMs. Your agent extracts flight details from free text and calls /v1/carbon autonomously.

    Confidence Score

    Every response includes a 0–1 confidence value. Show users transparently whether exact aircraft data or a fleet-average fallback was used.

    Ready for the AI era

    Your AI agent now speaks aviation

    Building a travel concierge, a booking bot, or autonomous logistics agents? With our Aviation MCP Server, logostream becomes a direct plug-and-play data layer for Claude, GPT, and any other LLM.

    A user asks: "How much CO₂ does the Emirates A380 to Dubai produce in Business?" — the agent extracts airline, aircraft, and route, autonomously calls /v1/carbon, and responds with numbers, a route map, and offset price. Zero middleware from you.

    Real aircraft data

    Performance data from the ICAO aircraft database — not generic averages. Specific fuel burn, range characteristics, and load factors per aircraft type.

    EU ETS offset price

    Live-refreshed EU ETS carbon price converted to per-passenger EUR offset cost. Economy and with-RFI variants both included.

    Stopovers supported

    Pass an array of intermediate IATA codes. The API calculates each leg independently and returns per-leg CO₂ plus route totals.
