x402 resource designs — pricing and settlement pending verification

No successful production settlement receipt is claimed here. A future receipt is trustworthy only if its own Ed25519 signature verifies at /gspc-verify.

The x402 status endpoint may describe challenges and resource names; that does not prove a price is current or that settlement succeeds. Inspect the endpoint response before relying on either. No price is asserted by this page.

Issuance

Planned settlement unverified

Proposed scoped measurement request for a named model, agent, or asset. Output and signature state must be checked in the response.

Evidence bundle

Planned settlement unverified

Proposed assembly of existing scoped cards for a named obligation. No universal evidence pack is available.

Eunomia data feed

Planned settlement unverified

Proposed dated-delta feed. No continuous feed or automatically signed bundle is claimed.

Proof bundle

Planned settlement unverified

Proposed request for a card’s exact-root inclusion material, when that card is actually a leaf of that root.

Custom audit

Planned settlement unverified

Proposed scoped measurement workflow. No signed card, PDF, or legal determination is promised by this page.

Proposed flow

  1. A client inspects the resource and current x402 status.
  2. If a valid HTTP 402 challenge is returned, the client validates its network, asset, recipient and amount.
  3. A wallet authorization and facilitator submission must remain explicit user actions.
  4. Only a confirmed on-chain result and a separately verified artefact receipt establish settlement and output.

Do not fund or sign from this page. Pricing and end-to-end settlement remain pending until a published successful receipt and transaction can be independently checked.

Receipt requirements

A successful future flow must expose the transaction hash, resource, network, asset, amount, artefact digest and signature material. None is implied merely by an HTTP 402 challenge.

What stays free

The board (/api/gspc), root (/root.json), corrections ledger (/api/corrections), MCP door (/mcp), A2A card (/.well-known/agent-card.json) and verifier (/gspc-verify) are public routes. Check their current responses and terms; this page makes no perpetual availability promise. We do not sell a legal-compliance determination, certificate, or rank.

What we eat

The current repository root is 9b426735bc7c0e94d32ce64ccd87605880c531350ca957ecccde5046bde505cd (154 leaves; Merkle root 2fe2a76f310ea79268c73a94543c91125fa7acc3bbf11ed489afdfeb845ea745). Its Ed25519 signature verifies and its exact preimage is witnessed in Rekor at log index 2714574265. Its OpenTimestamps proof has SHA-256 91dae23c5e4d8c4914fbfca77e8274e1ddfd71b00baadd8f58e43f3633bdfc99 and state STAMPED_PENDING_BITCOIN: there is no Bitcoin block confirmation. This root covers only its 154 listed leaves, not every card or measurement. See the exact-root witness.
