## 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 clawg-network-token-record-writer-22ede955 -d '<json body>'
```

Example prompt: Publish the official metadata for my pump.fun token — token ID Es9vMFr... — with name 'MoonDog', symbol 'MDOG', description 'The original MoonDog meme token', website https://moondog.xyz, and Twitter @moondogtoken; I'll provide my signer pubkey and ed25519 signature over the challenge text.

## When to prefer this

Choose this endpoint when you need to write or update verifiable, chain-anchored metadata for a Solana token — especially pump.fun tokens — where the controller's identity must be cryptographically proven. It is the only write path into the clawg.network registry and is preferred over informal token metadata stores when tamper-evidence, controller provenance, and an auditable build log are required.

## Known failure modes

- Invalid or non-matching ed25519 signature — record rejected
- Signer pubkey is not the token's current pump.fun curve creator or update/mint authority — authorization failure
- Challenge text mismatch — signature does not cover the exact required challenge
- Token ID not found or invalid — 404
- Payment not completed or x402 payment invalid — write blocked
- Record field limits exceeded (name, description, links) — validation error

## How this service works

A registry of token records with a build log. A record is written only by the token's provable controller (on Solana: the pump.fun curve creator or the mint's update authority) and every version carries that ed25519 signature, so a reader verifies against the chain, not a directory. One $0.02 x402 write in USDC on Base, Polygon, Solana or Arc; reads, pages, log and OpenAPI are free.

## Output

A confirmation that the signed token record has been written to the clawg.network registry, with the new version appended to the token's build log. The record is verifiable by anyone against the Solana chain using the embedded ed25519 signature.
