OpenStreetMap is built mostly by volunteers, with mapathons, HOT tasking projects and Wheelmap campaigns that pay nobody per edit, while big companies employ paid mapping teams at scale. Microtask apps pay for labelling but not for the open map. Fix the Map lets any small sponsor, a wheelchair group or a delivery startup, pay any local person per verified edit to the open map, with AI checking quality before money moves.
The data it runs on
The OpenStreetMap edit history API: each mapper’s changeset is fetched from the OSM API (changeset metadata and the diff), and gaps in the sponsor’s area are found with the Overpass API (for example shops without a name, entrances without a wheelchair tag, footways missing). Mappers attach a photo; open street-level imagery (Mapillary or Panoramax) is used as a second check where it exists. Limits: imagery coverage is patchy in many cities, OSM edits appear in public tiles after a short delay, and some facts (is the ramp too steep?) need a human eye. Fallback: low-confidence edits go to a second mapper for a paid review instead of auto-approval.
1. The mission
Pay people to fix the map everyone uses. Wheelchair users, couriers, and the apps they rely on all read the same open map. When a ramp or a shop name is missing, someone nearby should be paid to add it.
2. Why people can’t resist it
A visible dent in the world. The heat map turns from red to green, and you did that.
Small, fast money. A walk to the corner pays in minutes, with a quality score that feels like a game.
Purpose. Every ramp you add helps someone in a wheelchair plan a trip, in every app that uses the open map.
3. How it works for real
Login: email; passkey smart wallets for sponsors and mappers (Coinbase Smart Wallet or Privy); mappers link their OSM account with OAuth 2. Gas sponsored on Base.
Gaps: Overpass queries over the sponsor’s polygon count missing tags; a fast model (Gemini Flash or DeepSeek via OpenRouter) groups them into bounties with plain-language tasks.
Escrow: the sponsor’s USDC sits in a bounty contract on Base, one slot per bounty, with an expiry and refund.
Edit: the mapper edits in the in-app editor or any OSM editor, with the changeset hashtag #FixTheMap and a disclosure, following the OSMF Organised Editing Guidelines.
Verify: a worker fetches the changeset, validates tags against the OSM wiki schema, checks geometry, and a vision model (Gemini 2.5 Flash or GPT-4o mini) compares the photo with the tags. A quality score is computed in code from those checks.
Pay: the contract releases the bounty to the mapper’s wallet; x402 lets apps (routing, delivery) buy bounty slots per request.
4. Cost per use
About $0.02 per edit check: OSM API and Overpass calls are free (with fair use), the photo check costs about $0.01, tag and geometry validation is code. Payout gas on Base is a fraction of a cent, sponsored.
Free for mappers.Sponsors: 10% on top of bounties, or $49 per month for unlimited areas and coverage reports. Data stays open: sponsors buy improvements, not ownership.
5. Growth loop
Sponsors share the before and after heat map in their community; mappers share earnings and streaks; local apps that benefit (delivery, accessibility) become sponsors themselves. Each city’s leaderboard recruits the next mappers.
6. Risks and guardrails
Community norms: paid edits are disclosed per the OSMF Organised Editing Guidelines, with a public wiki page and hashtags. Bulk or automated edits are not allowed.
Bad edits for money: AI checks, a quality score, random human review, clawback within 14 days if the community reverts an edit.
Privacy: photos are not uploaded to OSM; faces and plates are blurred; no mapping of private homes’ details.
Safety: no bounties on highways or private land; daytime prompts for walking tasks.
7. MVP build order
