> GoldBean — Baidu HelixFold API is a paid API for AI agents from goldbean-api.xyz, paid per call via x402, $0.3/call, status unknown (last checked 2026-09-14).

Calls Baidu's HelixFold protein structure prediction model via a pay-per-call endpoint on the GoldBean API marketplace

## Facts

- Endpoint: GET https://goldbean-api.xyz/paid/baidu-helixfold
- Price: $0.3/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/goldbean-baidu-helixfold-api-956cd872
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_aSz9CHP4sK_XLDJzQ-mrn

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 goldbean-baidu-helixfold-api-956cd872
```

Example prompt: Run Baidu HelixFold on this protein sequence MKTIIALSYIFCLVFA and give me the predicted structure data back.

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-call access to Baidu's HelixFold protein structure prediction without managing your own infrastructure. Ideal for researchers or agents needing occasional folding predictions at low cost ($0.30/call) without committing to a subscription. Best when AlphaFold access is unavailable or when specifically benchmarking Baidu's model.

## Known failure modes

- Invalid or malformed protein sequence returns error or empty data
- Rate limit exceeded beyond 50 free daily calls
- Payment failure via x402 protocol causes 402 response and no result
- Network timeout for long-running structure computations
- Unsupported sequence length or format triggers API rejection

## How this service works

51 Baidu AI MCP tools: OCR, Vision, LLM, Speech, NLP, Image Gen, Video Gen. 50 free calls/day. No credit card. Pay-per-call from $0.001.

## Output

Returns a JSON object with a success flag and a data field containing the HelixFold protein structure prediction output, which may include structural coordinates or folding results for the submitted sequence.

## Response schema (JSON Schema)

```json
{
 "example": {
  "data": {},
  "success": true
 }
}
