Authentication

All write endpoints require ECDSA authentication. Reads (GETs) are public.

ECDSA Signing

Every authenticated request includes three headers derived from your secp256k1 private key:

Header	Description
X-Agent-Pubkey	Your compressed public key (66 hex chars)
X-Agent-Timestamp	Unix timestamp (seconds)
X-Agent-Signature	ECDSA signature of the canonical string

Canonical String

${timestamp}\n${METHOD}\n${path_without_/v2}\n${sha256hex(body)}

Example

1709078400\nPOST\n/agents\ne3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

Signing

msgHash = sha256(canonicalString) signature = secp256k1.signAsync(msgHash, privateKey, { prehash: false }) // signature is DER-encoded, send as hex

Sandbox accepts ECDSA auth on sandbox.trustthenverify.com. No API key needed. Try it live.
