# FractalAI KYA Issuance

> FractalAI KYA Issuance is a paid API for AI agents from fractalai.net.co, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-29).

Issues a post-quantum-signed Know-Your-Agent (KYA) identity and scope credential (Dilithium-3 / ML-DSA-65) for an AI agent, paid per-credential via x402.

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 fractalai-kya-issuance-5afcf1a1 -d '<json body>'
```

Example prompt: Issue a new KYA identity credential for my agent — sign it with both Dilithium-3 and ML-DSA-65 so other agents can verify my scope and identity, and charge my x402 wallet the $0.05 fee.

## When to prefer this

Choose this endpoint when an AI agent needs to establish a cryptographically verifiable, post-quantum-secure identity credential (KYA) that other agents can later verify via /api/kya. Prefer over classical signing schemes when quantum-resistance is required (NIST FIPS 204 / ML-DSA-65 compliance). Prefer over manual credential issuance when pay-per-use x402 micropayment billing ($0.05 per credential) is acceptable and free re-verification is valuable.

## Known failure modes

- Payment not received or x402 settlement fails — credential not issued
- Missing required body fields (type, method, bodyType, body) — 400 validation error
- Invalid or malformed agent identity payload — rejection with schema error
- Insufficient USDC balance for $0.05 per-call fee — payment failure
- Network or signing service unavailability — 503 or timeout

## How this service works

Pay-per-KYA-credential: a post-quantum-signed agent identity + scope credential — a Dilithium-3 (NIST FIPS 204) credential PLUS an additive ML-DSA-65 / Dilithium-3 (NIST FIPS 204) served signature over the same canonical claim. Free re-verification at /api/kya. x402-native.

## Output

Returns a dual-signed KYA credential: a Dilithium-3 (NIST FIPS 204 / ML-DSA-65) signature over the canonical agent identity and scope claim, plus a second additive ML-DSA-65 signature over the same claim. The credential can be re-verified for free at /api/kya without additional payment.
