## 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 oix-spendmap-climate-federal-climate-infrastructure-spending-d525b7ed
```

Example prompt: Pull the latest OIX SpendMap Climate report — give me the top 10 highest-scored federal climate infrastructure spending signals from primary government sources.

## When to prefer this

Choose this endpoint when you need scored, evidence-backed federal climate infrastructure spending intelligence sourced directly from USASpending.gov, with cryptographic proof of data provenance. Prefer this over generic procurement search tools when you specifically need (a) climate infrastructure market signals, (b) OIX evidence scoring for signal quality ranking, and (c) verifiable source digests for auditability. Not suitable for non-climate procurement categories or real-time contract award lookups.

## Known failure modes

- Payment failure (402): x402 micropayment of 0.25 USDC on Base mainnet not completed
- No matching observations: query term 'q' matches zero records in current source data
- Score filter too restrictive: minScore set too high returns empty observations array
- Limit out of range: limit parameter outside 1–25 range causes validation error
- Source data unavailability: upstream USASpending.gov API unreachable, causing stale or empty results
- Invalid query string: 'q' exceeding 120 characters rejected

## How this service works

Package any earning logic as an autonomous asset. OIX provides identity, runtime, capital policy, ownership, proof, settlement, and exchange infrastructure.

## Output

A JSON object containing: asset metadata (name, slug, market description), cryptographic proof digests (report and source SHA-256 hashes), product offer details (price, settlement method), and a decision object with the target buyer profile, an array of scored observations (each with URL, title, score, and evidence), total monitored record count, and number of returned observations. Protocol version is oix.machine-report/v1.
