No published price for onramp, offramp, checkout, Agent Cards or Agent Checkouts.\n\n**Paid.** Paid suits a builder who wants usage metering, credits and invoicing behind one API, with restricted and customer-bound keys, OAuth on the MCP server and a free plan that needs no card. No status page, SLA figure, API changelog or rate-limit numbers were found, both advertised OpenAPI links returned 404, and card payments need the builder's own Stripe account.\n\n## Before you call either\n\n### Crossmint API + Docs MCP\n\n1. Send an `x-idempotency-key` on every transaction or transfer create so a retry can't pay twice\n2. Use staging keys against testnets; production keys work on mainnets only, and Agent Checkouts has no staging at all\n3. On 429, wait and retry. No Retry-After header is documented, and writes are capped at 120 a minute per project\n4. Use Agent Wallets for x402 and MPP endpoints and Agent Cards for card merchants; they aren't interchangeable\n5. Append `.md` to any docs URL for a Markdown copy\n\n### Paid\n\n1. Call `https://api.agentpaid.io/api/v2` with `Authorization: Bearer \u003ckey\u003e`. A person creates the first key at app.paid.ai. No programmatic signup was found\n2. Give every signal a stable `idempotencyKey` and resend the same key on retry. Signals without one are not deduplicated\n3. Send at most 500 signals a request. A 429 rejects the whole batch, so wait for `Retry-After` and resend it all\n4. Read the `code` field on a 429. `CONCURRENCY_LIMIT_EXCEEDED` carries no `Retry-After` and clears when an analytics query finishes\n5. Install the Python SDK as `paid-python`, the name in its README and `pyproject.toml`. The quickstart's `pip install paid` names a package we could not check\n\n## Questions\n\n### Which is better for AI agents, Crossmint API + Docs MCP or Paid?\n\nCrossmint API + Docs MCP scores 67.1 (B) on agent readiness against Paid's 55.1 (C), and leads in every scored category.\n\n### Do Crossmint API + Docs MCP and Paid need an API key?\n\nCrossmint API + Docs MCP needs an API key. Paid takes an API key or an OAuth sign-in.\n\n### Can an agent call Crossmint API + Docs MCP and Paid without installing anything?\n\nYes. Crossmint API + Docs MCP has a hosted endpoint at https://www.crossmint.com/api and Paid at https://api.agentpaid.io/api/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/crossmint-vs-paid.json, and with the fewest tokens: https://www.anchorterminal.com/compare/crossmint-vs-paid.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"crossmint\", \"b\": \"paid\"}`.
