Open an empty folder in VS Code. Pick one of the 20 packs below, copy its setup command, paste it into the terminal, and press Enter. Your project will be populated and ready to run.
Requires Node.js 20+ · no GitHub repo or wallet needed · testnet only · private keys stay on your computer
The setup command downloads your chosen pack, fills your empty folder, and installs everything. When it finishes, run npm run demo.
GET onlyA research agent buys ranked market, academic, and news sources, then stops when its mandate cannot fund a fourth source.
GET /source/:sourceIdThe fourth purchase is rejected on-chain because its exact amount exceeds the mandate's remaining authority.
GET onlyAn agent buys a normalized page snapshot containing metadata, links, word count, and a content hash.
GET /snapshots/:pageIdPayment for one page cannot unlock a different page because the proof is bound to the exact requested resource.
GET onlyDemonstrate an allowlisted fixture-gateway pattern for a read-only API boundary.
GET /gateway/:service/:resourceIdAn upstream route outside the explicit allowlist is rejected before a payment challenge is issued.
GET onlyPublish free schema-described tool discovery while charging for selected tool results through a bounded HTTP integration.
GET /tools/:toolId/results/:fixtureIdThe offline consumer-policy check rejects a quoted tool price above its declared ceiling before any payment attempt.
GET onlyThe shared live consumer verifies the fixed price, settles once, retries the paid request once, and verifies the returned patch hash; an offline hook vector rejects a repeated 402 in the settled state.
GET /artifacts/:issueId/patchThe offline hook transition rejects a repeated 402 in the settled state instead of initiating another payment.
GET onlyOffline vectors rank bundled service-listing fixtures; the live plan buys the fixed alpha merchant route.
GET /services/:serviceId/results/:fixtureIdA wrong-merchant listing is excluded even though its declared price, quality, and latency signals would otherwise rank first.
GET onlyBuy a time-bounded reputation snapshot derived from signed execution events without treating a score as payment authority.
GET /agents/:agentAddress/reputationEvents signed by an issuer outside the configured trust set are excluded from the reputation calculation.
GET onlyA planner purchases research, verification, and synthesis artifacts as an explicit dependency graph.
GET /workflow/:caseId/:stageA failed verification stage prevents synthesis from running.
GET onlyBuy a bounded cryptographic workload and verify the returned digest independently on the consumer side.
GET /compute/sha256-chain/:tier/:seedIdThe deterministic hash function rejects an iteration count above 512 before hashing begins.
GET onlyA coding agent buys a deterministic hidden-test-result fixture for a known patch identifier.
GET /checks/:patchId/reportA patch identifier containing traversal syntax is rejected before fixture lookup.
GET onlyBuy a signed fixture statement binding an artifact hash to declared dependency and build-command metadata.
GET /attestations/:artifactShaA statement carrying an artifact hash different from the requested artifact fails local verification.
GET onlyOffline vectors compare fixture quotes and select the lowest-cost eligible provider; the live plan buys that fixed selected provider result.
GET /providers/:providerId/results/:promptIdA provider quote older than the configured freshness window is rejected before provider selection or payment.
GET onlyPurchase an exact asset-license version and receive content plus a receipt containing content and terms hashes and the settlement transaction hash.
GET /licenses/:assetId/:licenseVersionPayment for another asset or license version cannot unlock the requested content.
GET onlyThe live fixture merchant serves one owner-alpha dataset endpoint and receives payment when the agent unlocks that dataset.
GET /datasets/:ownerId/:datasetIdA dataset mapped to another owner is rejected by the endpoint's owner mapping before a payment challenge.
GET onlyAn agent buys a signed review decision only after a case reaches a ready state and the mandate remains valid.
GET /reviews/:caseId/decisionA distinct short-lived mandate expires before settlement against the ready delayed-case fixture, and the contract rejects payment.
GET onlyBuy a shipment passport summarizing custody handoffs, temperature excursions, and sensor continuity.
GET /shipments/:shipmentId/passportA missing sensor interval produces an explicit incomplete passport rather than an unsupported compliance pass.
GET onlyBuy the lowest-emission execution window that still meets a workload deadline and capacity requirement.
GET /schedules/:jobId/windowA forecast older than the scheduling freshness limit is rejected before a run window is selected.
GET onlyA fleet agent buys two planned route clearances; then the mandate user revokes authority and the third planned settlement fails closed.
GET /corridors/:routeId/segments/:segmentIdAfter two accepted segments the user revokes authority and the third settlement is rejected by the contract.
GET onlyA reference merchant demonstrates persistent replay admission, exact request binding, and safe recovery after restart.
GET /vault/:resourceIdAfter restart the exact same proof returns the byte-identical stored response without repeating verification or paid fulfillment.
GET onlyA purchasing agent evaluates approved vendor quote fixtures offline and buys one explicitly selected allowlisted quote pack.
GET /vendors/:vendorId/quote-packs/:requestIdA cheaper vendor outside the configured allowlist remains ineligible and cannot be selected for purchase.
Use the browser companion only after you have picked a starter. It shows the live 402 → payment → 200 flow, three settlements, and the contract-blocked fourth purchase.
Run the happy path first, then change one input at a time and observe where the request fails closed.
