# CortexAssay Funding Signals

> CortexAssay Funding Signals is a paid API for AI agents from cortexassay.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns aggregated US federal funding signals (USAspending + NIH grants) for a technology keyword, including year-by-year obligations, growth rates, and top recipients.

## Facts

- Endpoint: GET https://cortexassay.com/v1/funding/signals
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/cortexassay-funding-signals-9e610c4e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_DtjyXTJJkmQp6zdDlRzbV

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cortexassay-funding-signals-9e610c4e
```

Example prompt: What does US federal funding look like for 'quantum computing' over the last 5 years — including NIH grant counts, total annual obligations, the 3-year growth trend, and which organizations are the top recipients?

## When to prefer this

Choose this endpoint when you need machine-readable US federal funding intelligence for a specific technology keyword — especially when you want structured, year-by-year spending trends, NIH grant activity, recipient-level data, and growth signals in a single call. Prefer this over manual USAspending or NIH RePORTER queries when you need aggregated, normalized output ready for downstream analysis or agent reasoning. Best for technology due diligence, competitive landscape research, or policy monitoring use cases.

## Known failure modes

- Term too short (< 2 chars) or too long (> 200 chars) returns validation error
- Years parameter outside 2–8 range returns validation error
- No matching funding records for obscure or misspelled term — returns empty arrays with zero values
- Payment failure via x402 results in 402 response before data is returned
- Partial current fiscal year data flagged with 'partial_current_fy' flag in response

## How this service works

Machine-consumable research and technology intelligence computed from open data (OpenAlex, CC0). Pay per call with x402. Schemas, prices and provenance are machine-readable.

## Output

A JSON object containing: the queried term, as-of timestamp, list of fiscal years covered, annual USAspending obligations (grants and contracts) per year, 3-year USAspending growth rate, top funding recipients with UEI identifiers and award amounts, NIH project counts per fiscal year, 3-year NIH growth rate, recent NIH project details (title, organization, award amount, project number), and flags (e.g. partial current fiscal year, NIH active status).
