## 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 phmsa-pipeline-operator-search-a85f5bdc
```

Example prompt: Pull the PHMSA pipeline operator roster for all natural gas operators headquartered in Texas — show me up to 50 results sorted by operator name, including their HQ address and commodity.

## When to prefer this

Use this endpoint when you need to identify, enumerate, or look up pipeline operators from the official PHMSA federal registry — especially for market research, sales prospecting, environmental compliance checks, insurance underwriting, or regulatory due diligence in the oil-and-gas sector. Prefer this over general web search when you need structured, entity-resolved records with OPID linkage and HQ data.

## Known failure modes

- No results returned when operator name spelling differs significantly from PHMSA records — try partial names or OPID instead
- State filter must be a valid two-letter US state code; invalid codes return empty results
- Limit cap of 100 rows per call; larger datasets require multiple paginated requests
- Entity UUID may be null for operators not yet resolved in the business entity graph
- Stale records possible if PHMSA has not updated the underlying public dataset recently

## How this service works

Which pipeline operators are in a market, and who are they? Search the PHMSA pipeline operator roster by operator name, operator_id (OPID), HQ state, operator_type, or commodity. Returns the operator, HQ address, commodity, type, and entity-resolved company — the target universe for oil-and-gas services, pipeline-integrity & environmental consultants, energy insurers, and industrial real estate. PHMSA public-domain records.

## Output

Returns a list of matching pipeline operator records from the PHMSA registry, each including the operator name, PHMSA operator ID (OPID), HQ address, commodity type, operator/ownership type, and an entity-resolved company UUID that links to broader business data. Supports pagination and sorting.
