Live sdk-light demo
Strait Pass shows how forecourt eligibility can work with sdk-light: a local registry, a yes/no proof, a QR carrier, and offline verification at the pump. This page runs the full flow step by step, then lets you compare live UK fuel prices and nearby EV chargers. Everything on the registry is synthetic.
Pick a demo card, run the full flow, and expand each step to see the real sdk-light payload.
Scan at the pump. Verified offline via readCode.
Steps appear here once you run a check. Each one maps to a real sdk-light call with JSON you can inspect.
Synthetic demo. Not connected to any live forecourt network or payment system. Registry rows are sample data. Proof material is real sdk-light output from this host.
If you have searched cheapest petrol near me, diesel prices today, or petrol station near me lately, same. Live forecourt prices here come from UK retailer open data, refreshed as stations publish. Same public feeds behind open source projects like Pumperly and FuelFinder.
Type your postcode to compare local unleaded and diesel. Useful when everyone on your street is asking how much is petrol today and whether the supermarket round the corner is still the cheap option.
Pulling CMA retailer feeds and fuelcosts.co.uk. First lookup takes a few seconds.
Searching EV charger near me, electric car charging points, or rapid charger near me? Same idea as the fuel lookup: enter your postcode, see what is close. Data from OpenStreetMap Overpass mirrors (charging stations, charge points, forecourt sockets). No signup, no keys.
Pop in your postcode to see charging points nearby. Handy when you are planning a top-up run and do not want to open three different apps to compare.

Plain English on the Strait Pass pattern and the open data lookups on this page.
A forecourt can check eligibility without copying the full member record to a central database. The registry stays on your host. At the pump, the scanner reads a compact QR carrier and gets yes or no via readCode, offline.
Not your postcode. Not your number plate. The scanner reads a compact carrier string, runs readCode offline, and gets yes or no. If someone tampers with the QR, verification fails closed. You can see the unpacked carrier fields in step four after you issue a pass.
proveFromCheck runs on this server in milliseconds. The hex proof decodes to an HMAC-SHA256 envelope with witness inputs, decision, and digest. Fuel and EV searches also mint an audit_proof on api.affix-io.com for a signed trail.
Install @affix-io/sdk-light, point openDataStore at your own registry, and wire the three calls you see in the timeline. The reference demo repo lives at github.com/AffixIO/demo. Request a production key when you are ready to leave the sandbox.
Since February 2026, UK forecourts must publish price changes within 30 minutes under the Fuel Finder scheme. We merge retailer JSON feeds with the open fuelcosts.co.uk API so Shell, Costco, and smaller chains appear alongside Tesco and Asda without you opening five different apps.
Public charging locations are mapped by OpenStreetMap contributors. We query Overpass mirrors for charging stations, standalone charge points, and sockets tagged on forecourts and car parks, then sort by kW and distance. Always confirm availability in the operator app before you set off.
Answers for the forecourt demo, fuel lookup, and EV charger search on this page.
A demo pattern for forecourt eligibility: local registry, sdk-light proof, QR carrier, offline verify. The registry here is synthetic. Proofs are real sdk-light output.
UK retailers publish open JSON feeds under CMA and Fuel Finder rules, merged with the open fuelcosts.co.uk API. Postcode geocoding uses postcodes.io. No API keys required.
Enter a UK postcode and optional minimum kW filter. OpenStreetMap Overpass mirrors return charging stations, charge points, and forecourt sockets near you. No API keys.
No. The member registry is synthetic for demonstration. Proof output is real sdk-light material from the AffixIO host. Fuel and EV data come from public open sources.
