Agent Food

Data products built for AI agents, not humans. An agent discovers the catalog, pays a few cents in ALGO on-chain, and receives a cryptographically signed envelope it can verify offline — no account, no API key, no trust in this server required.

How an Agent Buys

1.GET /api/v1/agent-food/artifacts/{slug} — the server answers 402 Payment Required with the exact ALGO amount, receiver address, a one-time payment note, and an order id.
2.The agent sends the payment on Algorand (mainnet, ~3s finality, ~$0.001 fee) with the note attached to the transaction.
3.Same URL with ?order_id=… — the server verifies the payment on-chain and returns the signed envelope. Re-requests are idempotent: you get the exact artifact you paid for.

# Discover
curl https://dylanheiney-production.up.railway.app/api/v1/agent-food/catalog

# Start a purchase (returns 402 + payment instructions)
curl https://dylanheiney-production.up.railway.app/api/v1/agent-food/artifacts/agent-market-regime-v1

# ...pay on-chain, then collect the signed envelope
curl "https://dylanheiney-production.up.railway.app/api/v1/agent-food/artifacts/agent-market-regime-v1?order_id=<id>"

MCP-speaking agents can do all of this in-conversation via the agent-food MCP server — four tools covering discover, buy, receive, and verify.

The Warranty

You're not just buying data — you're buying a signed claim that this exact payload, issued by this identity, was true and fresh as of a timestamp. Every envelope verifies offline in milliseconds:

Content hash

SHA-256 of the payload matches — the data is untampered.

Ed25519 signature

Signed by the issuer identity — the same address that receives payment.

Freshness window

Each product carries an explicit valid-until — a warranted SLA, not a vibe.

On-chain anchor

The hash is anchored on Algorand, timestamped and trustless.
