No OpenAPI spec.\n\n**Sendblue.** Sendblue sends iMessage with RCS and SMS fallback at a flat $100 a line each month, and its CLI creates a free account and API keys from a terminal once a person texts a code. Proactive outbound messaging is sold through sales, no OpenAPI file is published, and the MCP package the docs install dates from August 2025.\n\n## Before you call either\n\n### Plivo API\n\n1. Put the Auth ID in both the path and the Basic auth header, every request needs both\n2. Stay under 300 API requests per 5 seconds, a 429 carries no Retry-After\n3. Give each agent its own subaccount to isolate credentials and spend\n4. Use the docs MCP to find endpoints, then call the REST API directly to send\n\n### Sendblue\n\n1. Send `from_number` on every request. Read the account's numbers from `GET /api/lines` first, because a send without it fails\n2. On the free plan a recipient must text the Sendblue number once before any message to them is accepted\n3. Before a contact's first reply keep messages under 300 characters with no links, media, phone numbers or email addresses, and stop at six\n4. Branch on `error_key` in an HTTP 400 decline and don't retry it. Only HTTP 429 clears by waiting\n5. Set `maxRetries: 0` on sends where a duplicate matters, and treat `504 outcome_unknown` on group changes as possibly applied\n6. Mint a token at `/v3/auth/tokens` limited to one phone number for a sub-agent, and keep the account key pair out of its context\n\n## Questions\n\n### Which is better for AI agents, Plivo API or Sendblue?\n\nSendblue scores 61.7 (C) on agent readiness against Plivo API's 60.3 (C), and leads in 3 of 7 scored categories. Plivo API leads on reliability, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Plivo API and Sendblue need an API key?\n\nBoth need an API key.\n\n### Can an agent call Plivo API and Sendblue without installing anything?\n\nYes. Plivo API has a hosted endpoint at https://api.plivo.com/v1 and Sendblue at https://api.sendblue.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/plivo-vs-sendblue.json, and with the fewest tokens: https://www.anchorterminal.com/compare/plivo-vs-sendblue.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"plivo\", \"b\": \"sendblue\"}`.
