See what an agent can do with Increase before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 37 stories with headroom

What would move Increase’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Agenticness — how well agents can access and operate the productConnect an agent via an official MCP server

    nonemoves agent-readyimpact 45

    Increase is a banking-API platform, so publishing an official MCP server for agent connectivity is a fair question, but the evidence pack shows only REST API docs, an OpenAPI spec, a CLI, and webhooks—no mention of an MCP server or MCP integration anywhere.

  2. Banking agent access — stories about banking agent access in this arenaAn agent can operate an account within policy — scoped credentials that let it read balances and initiate transfers under amount caps and counterparty allowlists, a use the vendor documents by name

    nonemoves PA Scoreimpact 30

    Increase's docs show general transfer APIs, holds, and optional human approval for transfers, but there is no evidence of a named feature for AI-agent scoped credentials with amount caps and counterparty allowlists — the story's specific banking-agent-access capability is unevidenced.

  3. Sponsor model — stories about sponsor model in this arenaThe platform ledger reconciles to the bank core — documented daily reconciliation between what the API reports and what the bank holds, the failure that sank Synapse-era programs

    nonemoves PA Scoreimpact 30

    Missing: documented reconciliation cadence/process, bank-core balance verification API or report, any third-party audit or attestation of ledger accuracy.

  4. Openness — open source, data portability, and self-hosting storiesExport all of my data in open formats and leave

    nonemoves PA Scoreimpact 30

    The evidence shows Increase exposes account, transfer, and entity data via a REST/JSON API and webhooks, but there is no documented bulk data-export feature, open-format data dump, or migration/offboarding tooling that would let a customer pull all their data and leave.

  5. Agenticness — how well agents can access and operate the productOperate the product with natural-language commands

    nonemoves Built-in AIimpact 30

    Evidence shows Increase is a REST/JSON banking API with docs, OpenAPI spec, and a CLI, but nothing indicates a natural-language command interface, chat/agent layer, or NL-to-API translation capability.

  6. Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent

    nonemoves agent-readyimpact 30

    Missing: scoped API key creation, permission/role-based access controls, agent-specific credential issuance documentation.

  7. Agenticness — how well agents can access and operate the productBuild against official SDKs

    nonemoves agent-readyimpact 30

    Evidence shows an OpenAPI spec, a CLI, and llms.txt/docs, but nothing in the pack documents official client SDKs (e.g., Python, Ruby, Node libraries) that AI-native developers could build against beyond the CLI tool.

  8. Agenticness — how well agents can access and operate the productExplore an interactive API reference with runnable examples

    nonemoves API qualityimpact 30

    Evidence shows only static markdown documentation and a raw OpenAPI spec, with no mention of an interactive API reference or runnable/try-it-out examples anywhere in the pack.
