# Federal Register Fisheries & Marine Resources Regulatory Changes Feed

> Federal Register Fisheries & Marine Resources Regulatory Changes Feed 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 Federal Register final and proposed rules for fisheries and marine resources since a given timestamp, each scored 1-10 for compliance impact, with effective dates and source links.

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 federal-register-fisheries-marine-resources-regulatory-changes-feed-42e71d54
```

Example prompt: Pull all Federal Register fisheries and marine resources regulatory changes since January 1, 2025, and only show me the ones with a compliance significance score of at least 7 — I want to see the title, effective date, and a link to the source for each.

## When to prefer this

Use this endpoint when you need machine-readable, scored, and timestamped fisheries and marine resources regulatory changes directly from the Federal Register — especially when you want to filter by significance threshold or date window for compliance workflows. Prefer this over the LLM digest sibling endpoint when you need raw structured data with source links rather than a summarized narrative.

## Known failure modes

- Invalid or missing 'since' ISO-8601 timestamp returns a validation error
- min_significance out of range (below 1 or above 10) returns a schema error
- limit exceeding 500 returns a validation error
- No matching changes in the time window returns count 0 and an empty changes array
- Payment not included or insufficient funds returns HTTP 402

## How this service works

Federal Register final & proposed rules affecting fisheries & marine resources (National Oceanic And Atmospheric Administration) since a timestamp — covering fishery, fishing, marine, catch limit, endangered — each scored 1-10 for compliance impact, with effective dates and primary-source links.

## Output

A JSON object containing a count of matching changes and an array of regulatory change records, each with a title, type (final/proposed rule), plain-language summary, compliance significance score (1-10), effective date, detection timestamp, entityId for further lookup, and a primary-source Federal Register URL.
