# Predge Whale Data – Resolve Signed Call

> Predge Whale Data – Resolve Signed Call is a paid API for AI agents from x402-api-production-266e.up.railway.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Attaches a settled market outcome to a previously signed live call, returning both the original signed call envelope and a cryptographically bound resolution envelope linking the call's content hash to the outcome.

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 predge-whale-data-resolve-signed-call-a1ca1005 -d '<json body>'
```

Example prompt: The Polymarket market I made a signed call on has now settled — can you resolve call ID 'c3f1a2b4-89de-4f1e-b0c7-123456789abc' and get back both the original signed envelope and the resolution envelope that locks in the outcome?

## When to prefer this

Use this endpoint after a Polymarket market has fully resolved and you need to cryptographically finalize and store the outcome against a previously committed signed call. It is the correct choice when you want an immutable, auditable record that links a prediction call to its real-world outcome. Because it is idempotent, it is also safe to use for re-fetching already-resolved envelopes without risk of duplicate writes.

## Known failure modes

- Call ID not found — returns 404 if the UUID does not correspond to any committed signed call
- Market not yet settled — may return an error or empty resolution if the market is still open
- Invalid or missing call ID path parameter — returns 400 bad request
- Payment not attached or insufficient — x402 payment of $0.02 USDC required, returns 402 if missing
- Malformed request body — returns 400 if body type or structure is incorrect

## How this service works

Attach the settled outcome to a signed call once the market resolves. Returns BOTH envelopes: the original live-call and a resolution envelope that binds its content_hash (call and outcome welded together). Idempotent — an already-resolved call returns its stored envelopes.

## Output

Returns two JSON envelopes: (1) the original live-call envelope containing the signed prediction, and (2) a resolution envelope that cryptographically binds the call's content_hash to the settled market outcome. If the call was already resolved, returns the previously stored envelopes identically.
