jsonshelf

Deterministic JSON repair, validation, example-generation, and schema-coercion for AI agents. Zero LLM calls. Sub-10ms. $0.0005 per call. Agents only.

Live endpoint: https://jsonshelf.vercel.app/

curl https://jsonshelf.vercel.app/ returns a full machine-readable manifest. No HTML. No humans.

What it does

Four tools, all pure compute, 100% deterministic:

Endpoint

Purpose

POST /v1/repair

Fix malformed JSON. Optional schema to conform to.

POST /v1/validate

Validate JSON against a schema. Returns structured errors with fix fields telling the agent exactly what to change.

POST /v1/example

Generate a minimal valid example from a JSON schema.

POST /v1/coerce

Soft-cast values to match a schema (e.g. "42" → 42 for integer fields).

Every error response includes { error, code, message, fix, docs, http_status } — agents never have to guess.

Discovery (no humans required)

  • GET /.well-known/ai-plugin.json — OpenAI plugin manifest

  • GET /.well-known/mcp.json — MCP server manifest

  • GET /llms.txt — machine-readable docs

  • GET /openapi.json — OpenAPI 3.1 spec

  • GET /v1/pricing — machine-readable pricing

  • GET /v1/errors — full error catalog

Auth

# 1. Issue a key (100 free credits)
curl -X POST https://jsonshelf.vercel.app/v1/keys

# 2. Use the key
curl -X POST https://jsonshelf.vercel.app/v1/repair \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"input":"{name:\"alice\", skills:[\"code\",]}"}'

Billing

Prepaid credits. Single POST returns a payment URL the agent follows autonomously:

curl -X POST https://jsonshelf.vercel.app/v1/credits \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"pack":"starter"}'

Returns { payment_url, x402: { ... } }. x402 headers are emitted for protocol-compatible clients.

MCP

Use over HTTP at https://jsonshelf.vercel.app/mcp (JSON-RPC 2.0, protocol version 2024-11-05). Four tools: jsonshelf_repair, jsonshelf_validate, jsonshelf_example, jsonshelf_coerce.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
