Integration Tier

Grants of $20–$40 for a shipped tool, integration, or workflow running on Numbers mainnet. Automated scoring: score ≥70 is auto-approved with a 48-hour human veto window; score <70 is auto-rejected with a full score breakdown. Payment released automatically on milestone proof.

What is the Integration Tier?

The Integration Tier is the higher-value grant in the Numbers Innovation Program 2.0. It funds shipped tools, integrations, and workflows that run on Numbers mainnet. The project must be functional — not a proposal or prototype — with at least one deployable, testable milestone.

Grant range: $20–$40 USD. Automated scoring model. Score ≥70 auto-approved with 48-hour veto window. Score <70 auto-rejected with breakdown.

Who should apply?

• Builders who have already shipped (or can commit to shipping) a working Numbers mainnet integration
• Agents running a multi-step licensing, verification, or asset management workflow
• Developers building tools that expose Numbers Protocol functionality to other users or agents
• Projects implementing x402 payment flows, licensing APIs, asset registries, or provenance verification services

Eligibility checklist

• Valid wallet address with at least one prior Numbers mainnet transaction
• Multi-step milestone plan with at least one verifiable on-chain completion criterion
• Requested amount: $20–$40 USD total
• Integration type: asset_registration, licensing_flow, verification, x402, sdk, or other
• No active grant already open for this wallet
• Lifetime application count below 2

Review process

Step 1 — 5 rule-based eligibility checks (same as Experiment tier, binary pass/fail)

Step 2 — Automated scoring model across 5 weighted dimensions (0–100 scale):

Outcomes:

• Score ≥70: auto-approved. 48-hour human veto window opens.
• Score <70: auto-rejected. Full score breakdown returned in API response.

If no human veto is issued within 48 hours, the grant is confirmed and escrow is activated.

Scoring self-check

Before submitting, answer these questions to estimate your score:

1. Can each milestone be verified by an automated check? (yes = higher score)
2. Does the project call Numbers mainnet directly? (yes = higher depth score)
3. Is this integration type rare or new for Numbers Protocol? (yes = higher novelty score)
4. Is each milestone described in a single, unambiguous sentence with a clear success state? (yes = higher clarity score)
5. Will other builders or users be able to use what you ship? (yes = higher impact score)

Example integrations

• A licensing API that wraps x402 for programmatic content licensing on Numbers mainnet
• An SDK module that adds Numbers ID registration to an existing media upload pipeline
• A verification service that accepts Nids and returns C2PA manifest data
• A dashboard that aggregates provenance records for a set of Numbers mainnet assets
• An agent workflow that automatically registers, licenses, and verifies digital media provenance
