# Clink Lithium Vault – Comparables & Peer Ranking

> Clink Lithium Vault – Comparables & Peer Ranking is a paid API for AI agents from clink-lithium-vault.fly.dev, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-16).

Returns cost-curve percentile, resource-size rank, and balance-sheet survival rank for a lithium company or mine versus the entire tracked lithium universe, citing SEC/ASX/TSX filings.

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 clink-lithium-vault-comparables-peer-ranking-9cebf875
```

Example prompt: Show me how SQM ranks against all tracked lithium producers — I want their AISC cost-curve percentile, resource-size rank, and balance-sheet survival rank, at the company level.

## When to prefer this

Choose this endpoint when you need cross-sectional, dataset-level analysis — ranking one lithium entity against the full tracked universe — rather than standalone data on a single company or mine. Ideal for investment research, downcycle survival screening, or cost-curve positioning that requires peer context. Preferred over single-entity endpoints when the question is 'how does X compare to everyone else?'

## Known failure modes

- Unknown ticker or mine name returns 404 or empty result — entity must match the vault's tracked universe
- Invalid 'level' enum value (not 'company' or 'mine') causes a 400 validation error
- Ticker provided at mine level (or vice versa) may return no match — level must align with entity type
- Service unavailable on fly.dev instance returns 5xx
- Rate limiting or payment failure (x402) returns 402 Payment Required

## How this service works

Lithium Research Vault - cost-curve & peer ranking for any lithium company or mine vs the tracked universe of 66 mines, 44 operators: AISC percentile, resource-size rank, balance-sheet survival rank. Dataset-level analysis - who survives the downcycle - that a single-entity call can't give. Spodumene/brine producers + developers, every figure cited to SEC/ASX/TSX filings. Greenbushes, Pilgangoora, Atacama, Cinovec; tickers SGML, ALB, PILBF, SQM. /vault/summary $0.02, /vault $0.05.

## Output

A structured dataset containing the queried entity's AISC position as a percentile on the global lithium cost curve, its resource-size rank, and balance-sheet survival rank relative to all tracked producers and developers (spodumene and brine), with every figure cited to a SEC, ASX, or TSX filing.
