PAID IMPLEMENTATION HANDOFFS

Put a runnable preflight at your Base signing boundary.

Two bounded implementation sprints pair an existing M2M Sentinel API plan with a reviewed, runnable handoff for an agent, wallet, solver, or transaction-automation codebase. The work reports capability evidence and explicit unknown states; it does not replace your own transaction policy.

See the boundary running

Two no-wallet technical proofs show the handoff shape before a buyer adapts it to a real codebase: an Openfort-compatible EIP-7702/ERC-4337 signing callback and a Locus-compatible standalone dynamic payment callback.

Growth Integration Sprint

$299

Matches the current Growth API plan price.

Use one codebase and one Base signing boundary to put a proxy- and EIP-7702-aware preflight patch into a runnable handoff.

  • One customer repository or codebase
  • One Base signing boundary
  • One runnable proxy/EIP-7702-aware preflight patch
  • A bounded seven-day implementation handoff
  • Existing Growth API access
Use Base checkout Use RapidAPI card access Send Growth intake

Pro Production Sprint

$999

Matches the current Pro API plan price.

Use a larger bounded scope when two transaction flows need runnable patches and deployment-ready handoff documentation.

  • Up to two transaction flows
  • Runnable integration patches
  • Deployment and handoff documentation
  • Existing Pro API access
Use Base checkout Use RapidAPI card access Send Pro intake

Use an existing purchase rail

The payment creates the normal API subscription; the server-side plan catalogue and the signed checkout quote remain the authority for price, duration, credits, and access. This surface adds no API tier, entitlement, x402 route, or price.

RapidAPI bills its own marketplace subscription and does not create a native sk_live_… key. A receipt or intent reference is used only to reconcile the requested handoff.

Smallest safe intake

  1. Choose the Growth or Pro plan through the checkout or RapidAPI link above.
  2. Send the receipt/reference and the short scope template by email.
  3. After scope is accepted, share public code, a redacted fixture, or a time-limited reviewed handoff channel.
Never send private keys, seed phrases, raw API keys, wallet credentials, or unreviewed access to a private repository. The sprint can start from public code, a minimal reproduction, or a redacted archive.

What the handoff contains

  • Scope confirmation against the purchased Growth or Pro plan.
  • Runnable patch(es) at the agreed signing boundary, with proxy and EIP-7702 resolution covered where applicable.
  • Reproduction and test commands, plus explicit unresolved cases and caller-owned policy decisions.
  • For Growth, a bounded seven-day implementation handoff. For Pro, deployment and handoff documentation that your team can review and run.
Neither sprint promises a safety verdict, exploit detection, guaranteed deployment, uptime, preferential support, or an ongoing SLA. The API's evidence and unknown-state semantics remain unchanged.
