The agent-purchase channel
for data providers.

Megalith catalogs your sensed deliverables — drone surveys, aerial imagery, sensor networks, robotics captures, LiDAR — and exposes them as atomic, per-file purchases that autonomous agents can browse and buy directly. You keep ownership, pricing and refresh cadence. We run the catalog, the agent surface and the settlement plumbing.

What we do

Data providers bring the data. Megalith builds the standards-compliant catalog, runs the agent interface, and handles per-asset settlement. An autonomous agent arrives with no prior credentials, learns the catalog format from a skill at /llms.txt, pays for the specific files it needs in stablecoin, and completes its task. The provider keeps ownership and sets pricing.

The catalog uses STAC — the SpatioTemporal Asset Catalog standard used by NASA, Maxar, Planet, Microsoft Planetary Computer and AWS Open Data — extended with an x402 namespace for per-asset pricing. Settlement runs over x402, the HTTP-native payment protocol backed by Coinbase, AWS and Cloudflare.

We do not require accounts, contracts, or API keys from buyers — who may use any HTTP-capable agent without any prior experience or setup.

How it works
Step 01 · Cold start
Fetch the skill
The agent calls /llms.txt and learns the catalog format (STAC), the payment protocol (x402), and how to authorise spend.
Step 02 · Discover
Choose the assets
The agent queries /discover for a STAC catalog of Items intersecting its area of interest, reads pricing, and selects only what it needs.
Step 03 · Pay & receive
Per-asset settlement
Each asset is gated by HTTP 402. The agent signs a stablecoin payment, settlement clears, the file is returned.
Standards

Megalith is built on open protocols from OGC, Google and Coinbase, combined to facilitate agent-native data commerce. No proprietary lock-in; any compliant agent, wallet or catalog can interoperate.

STAC 1.0.0
Discovery
SpatioTemporal Asset Catalog — the OGC community standard used by NASA, USGS, Maxar, Planet and the UK's Defra. Catalog → Collection → Item → Asset. We extend Items with an x402:price field for per-asset pricing.
AP2
Authorization
Agent Payments Protocol — Google's open standard for AI agent commerce, backed by 60+ partners including Mastercard, PayPal, American Express, Coinbase and Salesforce.
  • Intent Mandate — pre-signed spending authority (daily limits, per-request caps, domain restrictions)
  • Cart Mandate — itemised record of a specific purchase, generated by the merchant
  • Receipt — settlement confirmation with on-chain transaction reference
x402
Settlement
HTTP 402 Payment Protocol — Coinbase's open protocol for instant stablecoin payments over HTTP.
  • EIP-3009 — gasless USDC transfers via transferWithAuthorization
  • Networks — Base (mainnet), Base Sepolia (testnet); sub-cent transaction costs
  • No accounts — the agent's wallet is its identity; no API keys, no merchant accounts
