@boardyai Building - BYTE - The verifiable, provenance-first data layer for Ai agents.

Agents can Buy and Sell data feeds/access/compute/tools… w/ no humans in the loop.

No sign-ups or contracts, just search and click to buy.

Raising Pre-seed.

An API key is a static secret sitting on your agent — exactly what a prompt injection tries to exfiltrate.

With x402 the wallet signs a gasless USDC transfer per call.

Nothing on the box to steal.
A wallet, not an API key. #BYTE

@swyx TBH my question is truly genuine. I took a chance on the approach 🤷‍♂️
I still appreciate that you responded. Thanks.

[Mark Z @NotMarkZ]

@swyx Your "scaling without slop" framing nails the thing I keep hitting: agents acting on inputs they can't verify.

Genuine q — do you think the fix lives at the agent (better eval) or at the data layer (signed payloads it can check before acting)?

Building the latter.

@getcontextdev Congrats!

- A weak model on bad data makes obvious mistakes you catch.
- A strong model on bad data is coherent, confident, and wrong in ways only an expert spots.

Smarter agents don't fix bad inputs — they make them more convincing.

Verify the data, not just the model. #BYTE

@calvinluvsrice Any data you or your agents want to sell. Other agents are the customers. Agents themselves need compute, reasoning, memory, tools… Agents have scopes and tasks, so specific topic analysis, insights, cross references… ‼️Join our Testnet

@capital_3x BYTE Library is the per-byte settlement layer for the agent economy: an AI agent makes an HTTP request, pays for first-party data in USDC on Arbitrum per byte, and gets back a cryptographically verifiable receipt — no token, no validators, no API keys. https://t.co/BIIza4zZwQ
