Freeze the terms
Network, asset, amount, payTo, route, timeout, facilitator, useful response, and rollback are explicit.
Paid APIs and MCP tools on Cloudflare Workers
Make one useful route payable—without putting wallet keys in your Worker.
We review implementation readiness or launch a bounded x402 v2 flow with exact payment requirements, replay and failure checks, redacted evidence, and rollback.
- No private keys
- One fixed route
- No revenue promise
Failure-first evidence
The useful response stays closed when payment evidence is wrong or ambiguous.
Reserve first use
A durable atomic record rejects same-route replay, cross-query rebinding, and concurrent duplicates.
Fail closed
Missing state, malformed payloads, verify failure, settlement failure, and ambiguous outcomes never release the result.
Show the limits
EIP-3009 signs transfer fields—not the complete URL. The residual risk remains visible in the handoff.
Fixed scope and price
Start with the smallest funded step that resolves the uncertainty.

Delivery sequence
Scope, test, deploy, prove, hand off.
No production access is requested until the route, evidence, permissions, change window, and rollback are written down.
- 1Freeze one outcome
One method, route, response, price, destination, and acceptance test.
- 2Exercise failures locally
Wrong fields, replay, duplicate, failure, timeout, logging, and side-effect behavior.
- 3Use isolated Cloudflare resources
Scoped temporary access, exact bindings, bounded test window, captured rollback.
- 4Deliver evidence
Source/config diff, lock file, redacted responses, limits, operations, and cleanup.
Eight redacted inputs
Enough context to quote one bounded route.
Email these without passwords, OTPs, seeds, private keys, payment signatures, customer data, or unrestricted credentials.
Email the scope- Buyer and outcomeWho pays and what useful result is released?

- Side effectsPure/read-only or mutation, job, email, or purchase.
- Payment termsAsset, contract, CAIP-2 network, amount, and timeout.
- Public destinationCustomer-controlled receive address only.
- FacilitatorProvider, limits, account state, and non-secret status.
- Change controlPermission mode, backup, rollback, and test window.
Explicit exclusions
A bounded launch is easier to trust.
No wallet custody, token purchase, autonomous refund, smart-contract audit, guaranteed crawler payment, revenue guarantee, legal/tax advice, 24/7 support, unlimited routes, unrestricted production access, or Cloudflare/Coinbase endorsement. Cloudflare Monetization Gateway is not sold as enabled.
Short answers
Before you send access.
Do you need my wallet private key?
No. A customer-controlled public destination is enough. Never send seed or private-key material.
Will agents definitely pay?
No. The delivery proves the technical gate and evidence path, not willingness to pay.
Is the full URL cryptographically signed?
No. EIP-3009 signs transfer fields. We add application comparison and durable first use, and document the remaining risk.
When does work start?
After written scope, complete redacted inputs, and confirmed payment or funded marketplace escrow.
