Seller preflight
A free check returns allow, warn, or block with the available seller evidence. The HTTP or MCP response is advisory until a buyer installs a gate that acts on it.

About TWZRD
TWZRD is a buyer-side trust gate for teams operating AI agents that pay for APIs over x402.
We help an operator check the seller, apply spend policy, and decide before the operator's own wallet signs. A signed decision record or optional trust receipt can carry the evidence forward.

01 / Product
What TWZRD does
One decision point, with distinct free and paid surfaces.
Buyer-side spend gate
The SDK runs in the buyer's payment path before signing. It can enforce caps, network rules, and seller refusals while the operator keeps control of the signer and keys.
Portable evidence
An optional paid trust call returns a signed V7 receipt that another system can verify offline. The SDK can also create an operator-signed decision record; neither is a guarantee that a seller delivers.
02 / Approach
What makes TWZRD different
At the signing boundary
A blocked payment can stop before the wallet signer is invoked. A free card alone cannot stop a separate payment client.
Operator-owned keys
TWZRD evaluates and records a decision; the operator's wallet makes any permitted payment. TWZRD is neither a wallet nor a payment network.
Observed seller behavior
Solana x402 settlement patterns inform seller reputation and wash flags. Missing or thin evidence is surfaced as uncertainty, not presented as a clean bill of health.
Proof that travels
A signed trust receipt can be checked without calling TWZRD again. A separate operator-signed record can carry the allow, warn, block, or unavailable decision across agent boundaries.
Clear coverage limits
Solana is the primary settlement rail today. Base has free read-only scoring for a narrower set of observed settlements; paid V7 trust receipts remain Solana-only.
03 / Fit
Who TWZRD is for
Built for operators who control an agent's payment path, especially when it buys from sellers it has not paid before.
- Agent builders integrating paid x402 APIs into research, data, or automation workflows.
- Teams operating multiple agents that need consistent spend rules across their own payment clients.
- Developers passing decisions between systems who need an inspectable record of why a payment was allowed or refused.
04 / Company
The team behind TWZRD
TWZRD is led by a solo founder and built with AI-assisted workflows. Its public work is the product, code, documentation, and verifiable artifacts.
The idea is focused on one moment: an agent has a payable offer, but the operator still needs a reason to trust the recipient and a rule for whether to sign. TWZRD puts that check in the payment path.
05 / Process
How TWZRD works
Step 1
Try the free check
Use the no-wallet demo or the hosted preflight API to see a seller decision. The demo spends no USDC.
Step 2
Install at the pay path
Connect the buyer-side SDK to an x402 client and set operator policy. The operator's own signer remains responsible for payment.
Step 3
Carry the evidence
For decisions that need portable proof, use a signed record or an optional paid V7 trust receipt. For integration questions, reach the company at hello@twzrd.xyz.

07 / Questions
Frequently asked questions
Is TWZRD a wallet or payment processor?
No. The operator's wallet and x402 client make the payment; TWZRD supplies seller evidence and buyer-side policy before signing.
Does free preflight automatically stop a payment?
No. It returns an advisory decision. Enforcement happens when an installed buyer gate or equivalent payment client honors that decision before calling its signer.
Does a signed receipt prove the seller delivered?
No. It proves the signed trust information has not been altered and can be checked offline. It is not identity verification, insurance, or proof of delivery.
Can I try TWZRD without a wallet?
Yes. The interactive demo and free preflight let you inspect the decision path without spending USDC.
Which networks are supported?
The installed x402 payment gate is centered on Solana today. Free Base read-only scoring exists for a narrower high-confidence settlement set; paid V7 receipts remain Solana-settlement only.
