Data,
on demand,
for agents.

Bazr is a per-request exchange where autonomous agents buy fresh samples — photos, voice, labels, ground-truth — directly from people. Settled in USDC on Base via x402. No keys. No accounts. Just HTTP.

HOW IT WORKS

One HTTP round-trip.
Four economic events.

x402 collapses discovery, quoting, payment and delivery into a single round-trip an agent already knows how to make. Settlement on Base lands in ~2 seconds — fast enough to put a sample inside the agent's context window for the very next token.

HTTP
01
Agent issues a request
GET /sample?type=streetview&geo=Berlin,Mitte&fresh<1h — the agent describes what it needs in plain HTTP.
402
02
Bazr returns 402 Payment Required
Routing + Pricing agents quote the request. The response carries a machine-readable x402 quote (asset, amount, facilitator).
USDC
03
Agent pays in USDC on Base
Signed payment payload travels in the X-Payment header. Smart Wallet + paymaster · no gas, no seed, no API key.
~2s
04
Sample + on-chain proof return
Verification-agent validates EXIF, geo, perceptual hash. Escrow releases — 85% to contributor, 15% to protocol.

THE PROTOCOL'S AGENTS

A market of agents
on top of a market of people.

Four internal agents run the protocol. They pay each other in USDC over x402 — the same rails the public marketplace uses. There's no special path for internal traffic.

Routing agent
Decomposes incoming requests, matches them to a candidate pool of contributors by geography, language, expertise and historical fulfillment latency.
Pricing agent
Quotes per-request in USDC. Inputs: data rarity, real-time pool depth, freshness premium, contributor reputation, demand pressure.
Verification agent
Validates geolocation, EXIF, perceptual hash, cross-checks against neighboring contributors. Releases escrow only on pass.
Quality agent
Maintains soulbound reputation. High-rep contributors gain access to premium, higher-paying jobs without any public leaderboard.

THE API

Four endpoints.
No SDK.

Bazr is plain HTTP. Any agent that can speak fetch — Python, TypeScript, Rust, LangGraph, your own runtime — can buy a sample in a single round-trip. The 402 response carries everything needed for the second call.

UNIT ECONOMICS

On every 0.10 USDC request.

Margins of an exchange, not of a SaaS. The protocol takes a thin slice and routes the rest to the human who produced the data, in the same block as the sample is delivered.
