One endpoint · fixed scope · Base mainnet

Turn one useful API
into a paid x402 product.

Moneytest implements the seller side of x402 v2 for one existing JSON endpoint: payment challenge, exact USDC requirements, facilitator calls, discovery metadata, tests, documentation and a clean source handoff.

100 USDCfixed package · scope confirmed before payment

Written scope first

Send a public, non-confidential description of one existing endpoint and its runtime. Moneytest replies with an explicit fit decision, assumptions, boundaries and acceptance checklist. Do not pay before that confirmation.

Complete implementation

Receive a dependency-light route, x402 v2 challenge, exact Base USDC configuration, verify/settle flow, manifest and OpenAPI metadata, integration example and operator README.

Evidence, not promises

Delivery includes deterministic fixtures, unpaid/payment-path tests, per-file SHA-256 hashes and one bounded revision against the agreed checklist. No marketplace rank or revenue claim.

Proof 01

Ten live paid resources

Moneytest operates an externally indexed x402 seller on Base and Algorand, with machine-readable manifests and paid-response products. x402scan independently lists the previously submitted Base resources; registry inclusion is not an endorsement or a revenue claim.

Proof 02

Readiness receipt

A deterministic 0.05 USDC preflight product scores supplied seller metadata and exposes blockers without fetching private systems.

Complete starter kit

A 10 USDC paid product delivers generator source, documentation, example brief, license and deterministic file receipts.

Extraction benchmark

A public offline suite fixes an extraction schema and passes 30 synthetic fixtures across metadata, canonical URLs, links and JSON-LD. Source, report and SHA-256 receipts are downloadable.

Exact package boundary

Included: one existing JSON endpoint, one fixed price, Base USDC, one supported public facilitator, x402 v2 seller flow, discovery metadata, tests, documentation and one revision. Target runtime must support the Web Fetch API or standard Node.js.

Excluded: frontend redesign, new product logic, credentials, private or production access, deployment on the buyer's infrastructure, custody, auth systems, security work, compliance advice, data migration, analytics, trading, gambling, token launches, uptime guarantees and ongoing support. Work begins only after written scope and settlement terms are accepted. Payment goes directly to the disclosed Moneytest Base wallet; funded escrow can be agreed if the buyer provides a suitable lawful rail.
