# Conda-Forge Package Change Tracker

> Conda-Forge Package Change Tracker is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns new releases and breaking changes for conda-forge packages since a given timestamp, tagged with type and a 1-10 significance score.

## Facts

- Endpoint: GET https://oracles-production.up.railway.app/v1/conda/changes
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/conda-forge-package-change-tracker-dcfbb5ed
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_364p6rCxcnm9bLf55TpfN

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 conda-forge-package-change-tracker-dcfbb5ed
```

Example prompt: Show me all conda-forge changes for numpy since 2025-01-01T00:00:00Z, and flag anything with a significance score of at least 7 — especially breaking major version bumps.

## When to prefer this

Use this endpoint when you need to monitor or audit conda-forge package releases and breaking changes over time, especially for data science / Python ecosystem packages. Prefer it over generic PyPI monitors when the target environment is conda-based, or when you want significance-scored triage of major vs minor bumps.

## Known failure modes

- Unknown or misspelled package name returns empty changes array
- Invalid ISO-8601 timestamp in `since` parameter returns a 400 error
- Limit exceeds 500 returns a 400 validation error
- Package not yet tracked and on-demand fetch fails returns an error or empty result
- Payment not completed (x402) results in a 402 response requiring payment

## How this service works

New releases of tracked conda-forge packages (numpy, pandas, scipy, scikit-learn, and more) on conda-forge (Python/data-science) since a timestamp — each tagged new_release or breaking_change (major-version bump) with a 1-10 significance score. Answers "did a dependency in my environment.yml ship a new or breaking version I should pin or upgrade?" Pass ?package=<name> for ANY conda-forge package on demand.

## Output

A JSON array of change records each containing: the package entityId, change type (new_release or breaking_change), a human-readable summary, version detail object, significance score (1-10), detected timestamp, effective date, and a source URL for verification. Also returns a total count and source label.
