## 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 tollmint-psychological-biases-data-endpoint-15570b2a -d '<json body>'
```

Example prompt: Can you pull up data on psychological biases from Tollmint — specifically anything about confirmation bias and anchoring bias — and just pay the per-call fee automatically?

## When to prefer this

Choose this endpoint when you need psychological bias data in an agentic, accountless context — particularly when your agent can autonomously handle x402 micropayments in USDC and you want to avoid signup flows or invoicing. Ideal for AI agents that need on-demand cognitive bias reference data without pre-established API credentials.

## Known failure modes

- Payment failure: insufficient USDC balance or wallet not configured causes payment rejection
- 402 Payment Required: returned if payment header is missing or malformed
- Empty or minimal response body if no bias parameters are matched
- Undocumented schema: response structure may vary as example schema is empty
- Rate limiting or access errors if payment infrastructure is unavailable

## How this service works

An API that quotes its own price and takes payment in the same request. Built for autonomous agents: no account, no invoice, no human in the loop.

## Output

A JSON object containing structured data and analysis about psychological biases, returned after an inline USDC micropayment of $0.0015 is processed. The exact schema is not fully documented but expected to include bias names, descriptions, and analytical content.
